The anti foaming agent might not suck. You haven’t seen it without the agent, the liquid might just be SUPER prone to foam, and the agent knocks it down to just what you saw
@@andrelascasas3156 There are many disciplines in engineering. Very much so like in medicine. You wouldn't expect a heart surgeon to have the same understanding of the brain compared to a neurosurgeon.
@Swim Fan Yeah you are right in every sense. Sure they could have done more research and set up more appropriate tests. But I guess they also have a valid point in representing the general consumer and pc enthusiasts who have no idea and would just use the product as marketed. Whether they intended it or not, this video shows that it would have little or no performance improvements to using the graphene fluid over standard coolants in generic use case scenarios.
3:55 Pro-Tip: When draining a closed liquid loop, open an air-intake near the top of the loop before opening the drain port. It'll drain faster, and flow more smoothly. By "more smoothly", I mean you will avoid the -glug glug glug- type of flow that causes the stream to alternate between gushing and dribbling as it allows air to enter through the same hole the liquid is trying to exit from.
Not just a PC tip, any closed liquid system that has more than one possible opening. Great tip when you're changing your car's oil for example, open up the fill cap up top, then the plug on bottom.
@@askmeaboutmyscrotum3527 That was only removed after the cut, and at that point the pc was almost dry. We never actually see it drain with that cap off and a sizeable amount of liquid in it. I cant believe I had to point that out.
Yeah it turns out that thermal conductivity doesn't matter for a transfer fluid that much. The thermal conductivity mainly comes from the metal waterblock, which can be enlarged or shrunk quite easily to have better heat exchange with water. What is needed is thermal capacity in the water to soak up more heat, or a bigger pump. If you'd want any reasonable increase in performance and have thesame tubing and waterblock setup, you'd need to swap the liquid out to ammonia.
Why ammonia? I mean, yea, if you turn the whole thing into a refrigeration cycle that would do, but as a liquid ammonia has about half of water's heat capacity. Actually, water is just about the best medium for heat transfer between 280 and 400-ish K you can find. Nothing (I know) beats its heat capacity. You're right in that a larger pump would likely help out more just because it helps with the temperature gradient in the block. However, I suspect the bottleneck in this particular system is the water/air transfer, mostly because it always is. In fact, the higher conductivity liquid would probably show the largest improvement in settings where the pump is severely undersized. Any flowing liquid will form what's referred to as a "boundary layer" on solid surfaces, which is essentially a stationary film that heat must pass through by conduction rather than convection. This boundary layer is thicker when the flow velocity is lower.
@@misterjonas6991 About the heat capcity of water being higher? Depending on the temperature, ammonia has a higher heat capacity per litre. It defenately has higher heat capacity, but it's less dense. Point is, you don't really have to care about heat transfer that much if you're cooling to such extreme colds.
A 1% graphene addition to cooling fluid increases thermal conductivity by 61% and reduces viscosity by 31%. Note: is really only useful at high flow rates to give benefits over other coolants as it absorbs/dissipates heat quicker, but has identical heat capacity. What we would have needed to see in this test, is a high-flow pump setup, as you don't get the max benefits until you hit around 6L/m flowrate to take advantage of the increased thermal conductivity of the fluid. In addition, you could probably use a single pass high flow radiator for increased performance with this fluid with its higher heat transfer rate, instead of the 2 pass rad installed.
I love how everyone on this channel is supremely gifted in their knowledge of how computers work, but are some of the clumsiest human being on the planet.
@Tyler Perhaps ‘gifted’ wasn’t the most correct term to use. I simply mean that they are very knowledgeable about computers and tech in general. Far beyond that of the average person, at least. But that wasn’t even really the point of my post. I just find it amusing that people extremely skilled in one area can be lacking in another, seemingly simpler area. It does make for more entertaining videos though.
I regularly work with a variety of chemicals, including anti-foam. And the problem with anti-foam is it leaves behind a residue if you use too much of it, or when it dries, which would insulate the inner surface of your loop, preventing, or at least impeding thermal transfer. Your best bet is to simply design a loop that can be vented, and is properly configured to minimize foaming, which mainly just means there’s as little air as possible in the system.
Der8auer already did thermal testing, about 2K less temperature, so quite within the margin of error. I assume you would need much more graphene particles to get a decent effect, but then you would probably have to change the naming from water cooling to syrup cooling or something like that.
The only way to improve on water is with a fluid that has more thermal capacity not thermal conductivity. Thermal conductivity is how air coolers work.
@@Mrx1080 water already has an enormous heat capacity. But it's all meaningless if you don't get rid of it fast enough (unless you have a massive reservoir, then maybe)

@@michaelholland4317 Do you work for the company? Would love to see a video project that looks at potential buildup after for instance one year. I’d gladly volunteer for my YT channel, us VR guys always could use a degree or two cooler 😎
@@michaelholland4317 That's what everyone says about a year before everyone's loops start solidifying... I can't even count the number of coolants that were supposed to cause no buildup or degrade, and were later found to be horrible.
What did they say about the resistance across a little distance of coolant ? I would have thought graphene would act as wires if it really changed the water? I think its such a tiny amount added to make it go black,that the electrical conducivy didn't change much. The fluid will just be glycerine or something, which will just boost specific heat a bit... Or its the antifoaming agent only making a change?
I think you would find a larger temp change with short burst loads rather than sustained load. As with most water loops once the fluid has reached equilibrium you are limited by how much heat can be removed by the rad/fans.

"We recommend flushing the system of your previous coolant with de-ionised water before adding Go Chiller for maximum performance." Theirs a notice to flush the system, idk if that was done, or would alter the testing, Im bigggg interested in this coolant for 3 loops based off the color profile.
It would make sense, if the liquid were ionized I suppose you would expect the nano particles to align in direction, and preventing an optimal randomized directionality in the particles.
I agree, I enjoy Linus and other staff too, but Alex has a calm light-hearted demeanor about him that makes his videos feel like a breath of fresh air!
not really, this isnt the type of foaming they are meant to prevent, i made a post apart, the liquid is meant to prevent cavitation bubbles, these are bubbles that generate due to the drop in pressure in certain parts of the pump, they are an issue because when the pressure rises back up they will implode, and the incoming pressure of the liquid will be like the tiniest pistol shot ever, ohh so slightly eroding the surface in which the cavitation bubble had happened.
@@revdarian That's a good point, but i think those would form from shaking a bottle aswell. Though I'm not sure about that. Maybe for the cavitation bubbles to form you would have to hit the top of the bottle (lightly) with a hammer. Like when you hit a glass bottle on the top and the bottom pops off due to cavitation. Imho still slightly easier than Alex's drill method.
this one time i mixed two different mouth washes one was green one was purple. it made this very strange reaction where it was iridescent and constantly flowing all throughout it even days later. i've never replicated that but i'd love to see something like that in a coolant. seeing the turbulence in the water looks so sweet
That is actually interesting, the water must somehow get less conductive (unless its just clogged but im ignoring that) I cant remember off the top of my head what it could be, but it has to be something
@@defiantgg1831 I think it’s just impurities that it collects overtime. Or having it heat up & cool down over & over. Somehow changes the water, everything is clean. Fans & rad. No dust ect but my water always goes up 5-6c noticeably over time. I just put it down to impurities within the water that’s it’s gathered from the loop. Could just be micro impurities but enough to change the temps. Wouldn’t know without a microscope & comparing. The used water with new liquid.
@@Near2Future might be some of the particles of whatever is in the water, since there is still some even in distilled water that gathers, and blocks/slows down the flow or something im not at all sure, but its possible
“Graphene has been discovered in 2004 and been theorized to do… everything… well except leaving the lab” That was gold Edit: thanks for all of your likes I didnt expect it🤣
Guys next time when ever you try to fill up the coolant, open both ends, attach hose both the sides and hold them at equal vertical level above the system, this way you will never have to worry of air gap as filling up from above will simply push the air out from the lower side and holding them above will prevent your coolant from over flowing too. Good work on the video.
Okay, so I've worked with graphene liquids before and the reason why it foams is due to the dispersant and the stuff that keeps it in suspension. I doubt they have an anti foam agent in there as it would probably cause clumping and it to fall out of suspension. When we used it it would foam at even the slightest movement. Also you REALLY don't want this stuff on your skin, it's known to accumulate in the mitochondria of your cells, they don't currently know if that's bad, but everyone who takes an educated guess says it's bad.
"Bring in the engineers!" Two guys show up; one is exactly what you'd expect an engineer to look like, the other looks like he's there to take the first guy's lunch money, girlfriend, and job
I can assure you that at least 1 engineer I personally know looks like he probably only wash his hair once every 2 month. So the representation here isn't that far off.
@@falxonPSN I can also assure you one IT support guy in the company I used to work in looks like Dennis but dress like Linus and always "patrol" around the female engineer's cubicles.
I would expect a greater effect if smaller radiators were used. The pump speed also plays a role, why didn't you try to test low, medium and high speeds?
the speed of the coolant negligibly effects heat transfer unless you slow it way, way down. you're the first person to make the correct assumption that a smaller radiator would have shown a greater effect though.
I prefer the stock Noctua paste. Insanely good for paste (almost as good as liquid metal), and nearly impossible to fuck up. And it's free with your cooler!
The anti-foamer may be doing something, we don't know what their solution did without it, could be much worse. Also, I'd be afraid of the graphine buildup in the block and radiator.
I mean, technically speaking as long as the graphene doesn't completely block the flow it is conductive, so its not like it'd be a problem even if it coated it up since it would still transmit heat through itself.
@@Adierit Im starting to think thats exactly what needs to happen in order for it to work even better. A graphene tunnel where the water pushes the thermal load
also suspended particles will stick to the boundaries between the liquid and gas phase and reinforce the bubble boundary so therefore ensure the bubbles stay around for much longer, but if you overdose the suspended particles it can have opposite effect and just shred bubble formation
@@Adierit Theoretically a very small amount of buildup along the radiators would probably increase performance. Better thermal transfer rate material touching a larger amount of liquid to dissipate heat.
@@ImOnyxRS I don't buy it. Normally your heat flow would go from copper cold plate to water directly. You're saying adding another (imperfect) thermal interface would improve it? So the heat would go from copper to coated graphene particles to water. There's no way that's better, especially since the coating will be nonmetallic.
Graphite also makes a good lubricant so idk if it will be good or bad for your system long term. It's staying in that EK machine so we'll see how it holds up in a couple months. -Alex

@@christopherjc54 As a Chemist, I'd say you'd have to re-engineer not only the fluid, but also the cooling setup. A more volatile fluid is better at taking heat away, but it comes with a whole lot of problems itself. A denser fluid can also improve thermal conductivity with the same nanoparticles, but I wouldn't be sure if that could make the trick.
As an automotive engineer; I'd say if you re-engineer the cooling system you can get pretty much any cooling power you'd want with regular old tap water. No need for any carbon dirt.
@@Nevir202 And you would be absolutely right about that my good sir. There are several other properties that will impact the overall heat transfer, but the material properties of the particles and fluid impact it the most.
This video was amazing. Typical LTT shenanigans, making an absolute mess. Also really appreciate that you got the engineers in, and re-ran the test as you weren't happy. (Glad you did the complex system too though, as it looked sick!) Also "I have my highly technical, little agitator here. Normally Linus is good but he's on vacation unfortunately." - May be the best LTT joke ever.
Would have been cool to see with a temperature probe in the loop to measure fluid temperature. My guess is the average fluid temperature in the loop is lower by about 3-4 degrees with the graphine solution for a given setup/loop and might give a better delta for comparison. Also be interesting to measure temp in and out of radiator to see how they compare across that
I have that drill. The agitator fell out of the chuck because the brake on the drill stops and the heavy chuck spins itself free after a few hard stops. A fix is don't let the drill come to an immediate stop, or tighten the chuck after every time you do let it hard stop
Indeed, made that mistake myself too :D But seriously, i thought about draining and have a seperate drain pipeline in the system (on EK front panels 2nd lowest access point) with a close down ball valve+cap. I can drain everything other than the lower rad in 30 seconds, np. So like maintenance of CPU/GPU block is super easy.
Maybe 3 degrees cooler today, but when the particles start settling and jamming up microfins a month later you'll probably find that the performance tanks super hard.
graphite is technically a lubricant, so I would guess that there shouldn't be any issues with additional mechanical wear... settling is a legitimate concern, but graphite building up in the cooling fins could hypothetically improve thermal transmission, however depending on the size of the microfins blockages might be an issue over time... if instead of graphite, you had nanotubes and older generation fins in the loop, there could be a benefit to nanotubes getting caught in larger fins and increasing their surface area. If they're feeling insane, a water loop filled with gallium would be a lot of fun to see. especially if some "accidentally" uses an aluminium part...
@@davidpretorius2984 No, obviously graphene settling in microfins wouldn't improve heat conductivity, because you're reducing surface area AND/OR increasing flow resistance, and you're also adding material between the copper and the water, and thus reducing overall conductivity even if the thermal conductivity of the material is pretty good. Imagine for a moment coating the exterior surface of the fins on a standard air cooler in graphene. Even if that increased surface area, would that help heat conductivity? Obviously not. At the micro-level it's much worse, roughly analogous to filling most of the gaps between the air cooler fins with graphene and choking flow.
@@SovietGrazz the thickness is literally one molecule, however. And the thermal conductivity isn't "pretty good" it's off the charts and better than anything it's coating. IDK, it seems to me that if you look up graphene coolants for other applications (because they are out there) a coating of graphene on the interior surface is the point. In fact, several applications go so far to say that after being internally coated by graphene coolant the performance of the radiator increases and will eventually lead to much more efficient radiator technology in the future.
Let's not forget that the effectiveness of water cooling is not simply a factor of it's ability to conduct heat, but it's ability to store enormous amounts of energy to buffer heat transfer to the heat sink. Graphene coolant is trading it's ability to conduct for it's ability to store energy. So in order for it to perform exceptionally well, you need a bigger radiator on which the graphene can displace even more energy quickly. The gains in this case were probably only due to the radiator being oversized for the application. You overcame the limitations of the original coolant and it's ability to transmit energy and essentially discovered there was more capacity to transmit heat through the radiator than there was to store the energy in the coolant under load
When he said "you don't want bubbles forming on the microfins", well for that, where would the air come from? On the contrary you actually want surfactants (tensides) in your liquid that would break the surface tension and allow it to flow around the microfins better; but tensides are literally dish soap, so at the surface, they can tend to form air bubbles. I also think a small amount of surfactant can help remove the air better wherever it can be in the loop. Maybe the resulting foaming can be disconcerting, so maybe they added tensides to improve performance, and added anti foaming agents to then make it... not foam over in the reservoir and not look so scary.
Air conditioning doesn't run at a constant rate. It runs when the temperature is about 3-5 degrees warmer than the set temp then cools till it hits that temp again.
The question is, how well does it stay in solution over time. Is it going to be like most other liquids with particles suspended in it that drop out of solution after a while? You guys at LTT should setup a test system that you can run over a long period of time to test out it's long term stability.
Also fill up a few test tubes. Leave one at room temperature, one in the fridge and one in a hotbox or somewhere that's continuously warm and leave them there untouched for a month or twelve. That would show if the graphene stays in suspension or separates from the liquids. Also what about the liquid? How stable is it? What's the evaporation rate and so on.
@@blahorgaslisk7763 Evaporation rate shouldn't be an issue since it's inside a closed fluid system. Actually, even the suspension questions end up being not an issue since the fluid is constantly flowing and mixing around. Even if any settles, it would likely get resuspended as the fluid washes over the deposits. Though I suppose you could have a problem with micro deposits getting stuck in the tiny radiator fins. I would like to see them pour that fluid through some cloth filters and see how likely it is to get deposits getting caught in the tiny channels.
@@trapical I'm mostly interested in the evaporation rate because it's a new kind of cooling fluid and we don't really know much about how it reacts or what's in it at the moment. Besides even AIO's have a problem with evaporation, so I wouldn't say it's a none issue even though the reservoir should mean it would take a long time for it to become an issue in an open loop. As for suspension I don't think just having the fluid circulating is any guarantee that there wont be deposits. Just look at all the opaque liquids available. It seems most of these has a problem with deposits building up over time. Now this is one thing that might be less of a problem with this new fluid as the graphene should be extremely light and the particles very small. That should mean thy will stay suspended for longer, but until it's tested we really don't know for sure.
Tried this stuff in my water cooled laptop build because it looks SICK. Within a week my dry break quick disconnects started to become less and less dry break. They never leaked but they went from next to no fluid coming out to needing to keep a paper towel on hand when moving the laptop because about .5ml would be coming out. Looked great but with how quickly it was gunking up the connectors I flushed it.
@@Skylancer727 I dont know.. i ran mayhams nano fluid for 2½ years and there was no build up in the blocks.. it had a little in the pump but not that bad.. if its anything like PRIMO CHILL VUE then its bad.. How ever Graphite is a lubricant. so it might work out OK
agreed. Would somebody need to build a system designed to keep the fluid agitated by keeping it moving quickly and not having many horizontal lengths of tubing? What happens if it does settle, can it be re emulsified?
I'm super curius if the distilled water or the other coolant impacts the black liquid. It almost seems to be separating. A nice clean and dry to start with test bench would be cool. Also hope the liquid used in the machines isn't the same in both tests to prevent contamination. Nice video thanks for making it!
my son is using a product used in drag racing to cool his water cooling system. its called water wetter. on drag strips you' re not allowed to run antifreeze due to safety reasons. water does not cool as well as antifreeze/water mix, so water wetter was invented. it works very well in his system and prevents any "life" from forming
Distrust ANYTHING that says "graphene" or "diamond" on the label... :) The main ingredients in that snake oil is most probably pulverized graphite and a suspension/dispersion agent. No "graphene" has ever been near that bottle :) Also, like with all dyes and additives - the real test is letting the system run for a year. My guess is that you can just as well throw that system in the bin after a year, one bad thing about highly conductive additives is that they bond like superglue to metals after long exposure :/
I'd love to see the long term results with using this for a few months and if any issues come up. I can't shake the feeling that it'll gunk up components over extended periods of time. Hopefully I'm wrong. Because it DOES look cool in a custom loop.
Graphene's hardness is pretty low so optimistically it won't grind up components, while graphene is electrically conductive it seems the suspension limits that to something similar to salty water or comparable cooling solutions. My only worry is it clogging up the impeller in the pump or the micro-fins in the cooling element since it seems to only barely be in suspension. A longer-term test would be great to see because it does look amazing even if you ignore the marginal cooling efficiency improvements.
I didn't watch the vid, but there is a product called Water Wetter, for automobile cooling systems that actually does enhance cooling. A magazine test said 2 bottles, instead of the 1 recommend on the label, actually increased cooling. So, I bought a couple bottles and tried it. Sure enough my coolant temp dropped about 5C. During the summer, I ran mostly purified water with a couple bottles and it worked with typical coolant or plain water. I'm not sure how compatible it would be with pc liquid cooling parts and you'd have to refigure the rate of 2 bottles to 1 gallon of water for your reservoir, but the product did actually work.
i love the channel now being variety in hosts nowadays, ik the boss is on a vacation but seeing this kind of direction of the channel is going is wholesome, being more like a team.
I wonder how the graphene particles affect the inside of the tubes and pump over time... Like does it scratch up/cut the inside of soft, hard plastic or rubber tubing?
@@honeybadger6275 yeah i don’t even give a damn about its „superior performance“ either. Just call it fancy coolant and people would still buy it all I’m concerned about is that stuff coming out of suspension literally everywhere constantly and forcing me to clean out every single component of my loop regularly cause that’d just be much more of a pain than fancy looking coolant is really worth to me
You should do a long term (6months or so) of constant use with a heavy load put on for like 3-4 hours a day to see if the heat causes the graphine to solidify to cooling fins in a cpu/gpu water block and since its more viscous and heavier per millilitre than distilled water and see what wear/flow it does on the pump
the issue is the temperature delta. In a car the coolant is around 100c (212f), and ambient air is going to be, let's say 25c (or 77f). That's a 75c (165f) difference between the coolant and the air you are trying to dissipate heat into. In a watercooled rig what's the delta between coolant temp and ambient? 10, may 15c (50-59f)? There's just not all that much improvement to be had from the coolant itself. Even differences in the radiator itself are going to be minimal with those kinds of delta numbers. I'm sure water wetter would help, but the difference it will make is going to be very minimal. If we want to see significantly lower core temps, we need to either improve the thermal conductance of the die itself, or go sub ambient.
Iirc, the water-wetter helps by preventing localized boiling at hot spots in the engine block. If your die never gets near the boiling point of the coolant that's probably not benefit to you.
As the other comments say, I don't it will really do anything or something significant, but, "this is LTT!" (Read as in "this is Sparta!") So yeah! They should do that video Ltt style.
Water wetter will not make you engine run cooler, it raises the boiling point significantly so you can be safe at the high temps you see at the drag strip. IIRC it was meant to be added to engines running straight water. If you have antifreeze/coolant already it will do nothing they aren't already doing.
Seems like a very cool fluid! But im also very interested in a long term test vs. a „normal“ coolant to see if there is more or less abrasion on the coolers and if there is more or less residue from the particles falling out of solution. Evaporation-rate shouldn’t be significantly changed vs. normal coolant or distilled water and Evaporation-rate is also dependent on how airtight your loop is.
For the next edition of Sketchy Heatsinks, they should try to make this with graphite powder and water, and see if it does anything. Or, make a heatsink out of graphene sheets
Curious if the graphene in this liquid could also offer a potential lubricating effect on the pump or other parts of the system, judging from the lubricating properties of graphene and graphite.
WAIT A MINUTE. If the previous coolants had that "layer developing" property, it's possible that the protective layers those formed were degrading the potential performance of the suspended graphene particles. Just a thought.
@@joshuaford4460 The second test was the one that showed actual improvement. There might have been something in the first tests other coolant that interfered slightly.

Place a small, spirally bent wire into the drain, facing downwards (with a parabolic curve if you have the pipe sideways) and it should do the trick, just make sure the wire is somewhat same size as the drainage pipe. The draining stream should follow it.
When comparing keep in mind your cryofuel was used. It would have picked up ions over it's life in the loop. Fresh fluid might be less conductive. Same goes with water, after a while of running in a loop it will pick up ions from the loop components.
The bigger your radiators are, the less temp-difference you'll see... It is better to invest in a bigger radiator. This kind of fluid is only useful if you have small radiators en high temps!

3:55 Pro-Tip: When draining a closed liquid loop, open an air-intake near the top of the loop before opening the drain port. It'll drain faster, and flow more smoothly.
By "more smoothly", I mean you will avoid the -glug glug glug- type of flow that causes the stream to alternate between gushing and dribbling as it allows air to enter through the same hole the liquid is trying to exit from.
I was very surprised he didn't do that in the video.
Not just a PC tip, any closed liquid system that has more than one possible opening. Great tip when you're changing your car's oil for example, open up the fill cap up top, then the plug on bottom.
You would think this is common sense but 🤷🏻♂️
I literally can't believe I have to point this out. But YOU CAN SEE THE OPEN PORT AT THE TOP OF THE SYSTEM. He literally did this you guys
@@askmeaboutmyscrotum3527 That was only removed after the cut, and at that point the pc was almost dry. We never actually see it drain with that cap off and a sizeable amount of liquid in it. I cant believe I had to point that out.
Yeah it turns out that thermal conductivity doesn't matter for a transfer fluid that much. The thermal conductivity mainly comes from the metal waterblock, which can be enlarged or shrunk quite easily to have better heat exchange with water. What is needed is thermal capacity in the water to soak up more heat, or a bigger pump. If you'd want any reasonable increase in performance and have thesame tubing and waterblock setup, you'd need to swap the liquid out to ammonia.
And then your PC would smell GREAT
That's why I use my own piss as coolant
Why ammonia? I mean, yea, if you turn the whole thing into a refrigeration cycle that would do, but as a liquid ammonia has about half of water's heat capacity. Actually, water is just about the best medium for heat transfer between 280 and 400-ish K you can find. Nothing (I know) beats its heat capacity.
You're right in that a larger pump would likely help out more just because it helps with the temperature gradient in the block. However, I suspect the bottleneck in this particular system is the water/air transfer, mostly because it always is. In fact, the higher conductivity liquid would probably show the largest improvement in settings where the pump is severely undersized. Any flowing liquid will form what's referred to as a "boundary layer" on solid surfaces, which is essentially a stationary film that heat must pass through by conduction rather than convection. This boundary layer is thicker when the flow velocity is lower.
@@misterjonas6991 About the heat capcity of water being higher? Depending on the temperature, ammonia has a higher heat capacity per litre. It defenately has higher heat capacity, but it's less dense.
Point is, you don't really have to care about heat transfer that much if you're cooling to such extreme colds.
A 1% graphene addition to cooling fluid increases thermal conductivity by 61% and reduces viscosity by 31%. Note: is really only useful at high flow rates to give benefits over other coolants as it absorbs/dissipates heat quicker, but has identical heat capacity. What we would have needed to see in this test, is a high-flow pump setup, as you don't get the max benefits until you hit around 6L/m flowrate to take advantage of the increased thermal conductivity of the fluid. In addition, you could probably use a single pass high flow radiator for increased performance with this fluid with its higher heat transfer rate, instead of the 2 pass rad installed.
Open the fill port before you open the drain port. This way air can replace the water and the drain will flow better.

But that wasn’t even really the point of my post. I just find it amusing that people extremely skilled in one area can be lacking in another, seemingly simpler area. It does make for more entertaining videos though.
I regularly work with a variety of chemicals, including anti-foam. And the problem with anti-foam is it leaves behind a residue if you use too much of it, or when it dries, which would insulate the inner surface of your loop, preventing, or at least impeding thermal transfer. Your best bet is to simply design a loop that can be vented, and is properly configured to minimize foaming, which mainly just means there’s as little air as possible in the system.
Der8auer already did thermal testing, about 2K less temperature, so quite within the margin of error. I assume you would need much more graphene particles to get a decent effect, but then you would probably have to change the naming from water cooling to syrup cooling or something like that.
I wonder what the optimal ratio is.

What did they say about the resistance across a little distance of coolant ? I would have thought graphene would act as wires if it really changed the water? I think its such a tiny amount added to make it go black,that the electrical conducivy didn't change much. The fluid will just be glycerine or something, which will just boost specific heat a bit... Or its the antifoaming agent only making a change?
I think you would find a larger temp change with short burst loads rather than sustained load. As with most water loops once the fluid has reached equilibrium you are limited by how much heat can be removed by the rad/fans.

Here's a tech tip for your foaming test:
1) put liquid in a bottle
2) close the lid of the bottle
3) shake the bottle
4) observe the foamage
He also used the same cloth thing for all liquids. So there’s some contamination.
@@salluna1957 not significant contamination, but yes
👏👏👏 you did it.
not really, this isnt the type of foaming they are meant to prevent, i made a post apart, the liquid is meant to prevent cavitation bubbles, these are bubbles that generate due to the drop in pressure in certain parts of the pump, they are an issue because when the pressure rises back up they will implode, and the incoming pressure of the liquid will be like the tiniest pistol shot ever, ohh so slightly eroding the surface in which the cavitation bubble had happened.
@@revdarian That's a good point, but i think those would form from shaking a bottle aswell. Though I'm not sure about that. Maybe for the cavitation bubbles to form you would have to hit the top of the bottle (lightly) with a hammer. Like when you hit a glass bottle on the top and the bottom pops off due to cavitation. Imho still slightly easier than Alex's drill method.
this one time i mixed two different mouth washes one was green one was purple. it made this very strange reaction where it was iridescent and constantly flowing all throughout it even days later. i've never replicated that but i'd love to see something like that in a coolant. seeing the turbulence in the water looks so sweet

Guys next time when ever you try to fill up the coolant, open both ends, attach hose both the sides and hold them at equal vertical level above the system, this way you will never have to worry of air gap as filling up from above will simply push the air out from the lower side and holding them above will prevent your coolant from over flowing too. Good work on the video.
Okay, so I've worked with graphene liquids before and the reason why it foams is due to the dispersant and the stuff that keeps it in suspension. I doubt they have an anti foam agent in there as it would probably cause clumping and it to fall out of suspension. When we used it it would foam at even the slightest movement. Also you REALLY don't want this stuff on your skin, it's known to accumulate in the mitochondria of your cells, they don't currently know if that's bad, but everyone who takes an educated guess says it's bad.
I don't know, that sounds like an origin story to me...

I would expect a greater effect if smaller radiators were used. The pump speed also plays a role, why didn't you try to test low, medium and high speeds?
the speed of the coolant negligibly effects heat transfer unless you slow it way, way down. you're the first person to make the correct assumption that a smaller radiator would have shown a greater effect though.
That's why I stick to noctua air coolers and kryonaut paste in a tight pentadot configuration.
I prefer the stock Noctua paste. Insanely good for paste (almost as good as liquid metal), and nearly impossible to fuck up. And it's free with your cooler!
The anti-foamer may be doing something, we don't know what their solution did without it, could be much worse. Also, I'd be afraid of the graphine buildup in the block and radiator.
I mean, technically speaking as long as the graphene doesn't completely block the flow it is conductive, so its not like it'd be a problem even if it coated it up since it would still transmit heat through itself.
@@Adierit Im starting to think thats exactly what needs to happen in order for it to work even better. A graphene tunnel where the water pushes the thermal load
also suspended particles will stick to the boundaries between the liquid and gas phase and reinforce the bubble boundary so therefore ensure the bubbles stay around for much longer, but if you overdose the suspended particles it can have opposite effect and just shred bubble formation
@@Adierit Theoretically a very small amount of buildup along the radiators would probably increase performance. Better thermal transfer rate material touching a larger amount of liquid to dissipate heat.
@@ImOnyxRS I don't buy it. Normally your heat flow would go from copper cold plate to water directly. You're saying adding another (imperfect) thermal interface would improve it? So the heat would go from copper to coated graphene particles to water.
There's no way that's better, especially since the coating will be nonmetallic.

Did my master thesis on this and yes depending on the ratio and the material suspend in the nanofluid this is entirely plausible.
How do you think one might get close to 7 degrees with this fluid? (or does the fluid need to be re-engineered for that kind of a result?)
@@christopherjc54 As a Chemist, I'd say you'd have to re-engineer not only the fluid, but also the cooling setup. A more volatile fluid is better at taking heat away, but it comes with a whole lot of problems itself. A denser fluid can also improve thermal conductivity with the same nanoparticles, but I wouldn't be sure if that could make the trick.
As an automotive engineer; I'd say if you re-engineer the cooling system you can get pretty much any cooling power you'd want with regular old tap water. No need for any carbon dirt.
I would think though, that the compounds used to maintain suspension of the particles would be a bigger factor than the particles themselves, eh?

Would have been cool to see with a temperature probe in the loop to measure fluid temperature. My guess is the average fluid temperature in the loop is lower by about 3-4 degrees with the graphine solution for a given setup/loop and might give a better delta for comparison. Also be interesting to measure temp in and out of radiator to see how they compare across that
I have that drill. The agitator fell out of the chuck because the brake on the drill stops and the heavy chuck spins itself free after a few hard stops. A fix is don't let the drill come to an immediate stop, or tighten the chuck after every time you do let it hard stop

"This system is really not easy to drain guys"
...
Indeed, made that mistake myself too :D But seriously, i thought about draining and have a seperate drain pipeline in the system (on EK front panels 2nd lowest access point) with a close down ball valve+cap. I can drain everything other than the lower rad in 30 seconds, np. So like maintenance of CPU/GPU block is super easy.
You know when you open the drain before the fill port.
Maybe 3 degrees cooler today, but when the particles start settling and jamming up microfins a month later you'll probably find that the performance tanks super hard.
Also that is graphene dust so in the long term gonna mechanically corrode you loop, the pump gonna die in one year if things goes good
The settling that happened in that cup just while they were filming didn't leave me with a lot of confidence.
graphite is technically a lubricant, so I would guess that there shouldn't be any issues with additional mechanical wear... settling is a legitimate concern, but graphite building up in the cooling fins could hypothetically improve thermal transmission, however depending on the size of the microfins blockages might be an issue over time... if instead of graphite, you had nanotubes and older generation fins in the loop, there could be a benefit to nanotubes getting caught in larger fins and increasing their surface area.
If they're feeling insane, a water loop filled with gallium would be a lot of fun to see. especially if some "accidentally" uses an aluminium part...
@@davidpretorius2984 No, obviously graphene settling in microfins wouldn't improve heat conductivity, because you're reducing surface area AND/OR increasing flow resistance, and you're also adding material between the copper and the water, and thus reducing overall conductivity even if the thermal conductivity of the material is pretty good.
Imagine for a moment coating the exterior surface of the fins on a standard air cooler in graphene. Even if that increased surface area, would that help heat conductivity? Obviously not. At the micro-level it's much worse, roughly analogous to filling most of the gaps between the air cooler fins with graphene and choking flow.
@@SovietGrazz the thickness is literally one molecule, however. And the thermal conductivity isn't "pretty good" it's off the charts and better than anything it's coating. IDK, it seems to me that if you look up graphene coolants for other applications (because they are out there) a coating of graphene on the interior surface is the point. In fact, several applications go so far to say that after being internally coated by graphene coolant the performance of the radiator increases and will eventually lead to much more efficient radiator technology in the future.
Let's not forget that the effectiveness of water cooling is not simply a factor of it's ability to conduct heat, but it's ability to store enormous amounts of energy to buffer heat transfer to the heat sink.
Graphene coolant is trading it's ability to conduct for it's ability to store energy. So in order for it to perform exceptionally well, you need a bigger radiator on which the graphene can displace even more energy quickly.
The gains in this case were probably only due to the radiator being oversized for the application. You overcame the limitations of the original coolant and it's ability to transmit energy and essentially discovered there was more capacity to transmit heat through the radiator than there was to store the energy in the coolant under load
12:31 Maybe the "anti-foaming agent" is more of a film that traps bubbles on the surface and prevents more air from getting in?
When he said "you don't want bubbles forming on the microfins", well for that, where would the air come from? On the contrary you actually want surfactants (tensides) in your liquid that would break the surface tension and allow it to flow around the microfins better; but tensides are literally dish soap, so at the surface, they can tend to form air bubbles. I also think a small amount of surfactant can help remove the air better wherever it can be in the loop.
Maybe the resulting foaming can be disconcerting, so maybe they added tensides to improve performance, and added anti foaming agents to then make it... not foam over in the reservoir and not look so scary.

i don't even know what they have used to flush the system and how many times they've flushed it
Air conditioning doesn't run at a constant rate. It runs when the temperature is about 3-5 degrees warmer than the set temp then cools till it hits that temp again.
The question is, how well does it stay in solution over time. Is it going to be like most other liquids with particles suspended in it that drop out of solution after a while? You guys at LTT should setup a test system that you can run over a long period of time to test out it's long term stability.
Also fill up a few test tubes. Leave one at room temperature, one in the fridge and one in a hotbox or somewhere that's continuously warm and leave them there untouched for a month or twelve. That would show if the graphene stays in suspension or separates from the liquids. Also what about the liquid? How stable is it? What's the evaporation rate and so on.
@@blahorgaslisk7763 Evaporation rate shouldn't be an issue since it's inside a closed fluid system.
Actually, even the suspension questions end up being not an issue since the fluid is constantly flowing and mixing around. Even if any settles, it would likely get resuspended as the fluid washes over the deposits.
Though I suppose you could have a problem with micro deposits getting stuck in the tiny radiator fins. I would like to see them pour that fluid through some cloth filters and see how likely it is to get deposits getting caught in the tiny channels.
Didn't he fill that PC up with just straight premix though? Pretty sure he was supposed to add like distilled water to that no?
@@trapical I'm mostly interested in the evaporation rate because it's a new kind of cooling fluid and we don't really know much about how it reacts or what's in it at the moment. Besides even AIO's have a problem with evaporation, so I wouldn't say it's a none issue even though the reservoir should mean it would take a long time for it to become an issue in an open loop.
As for suspension I don't think just having the fluid circulating is any guarantee that there wont be deposits. Just look at all the opaque liquids available. It seems most of these has a problem with deposits building up over time. Now this is one thing that might be less of a problem with this new fluid as the graphene should be extremely light and the particles very small. That should mean thy will stay suspended for longer, but until it's tested we really don't know for sure.

@@sushimshah2896 Dude, of course it's not a real person.
This is like watching a kid in his dads shed, all the expensive toys and no idea how to use them.
Distrust ANYTHING that says "graphene" or "diamond" on the label... :) The main ingredients in that snake oil is most probably pulverized graphite and a suspension/dispersion agent. No "graphene" has ever been near that bottle :)
Also, like with all dyes and additives - the real test is letting the system run for a year. My guess is that you can just as well throw that system in the bin after a year, one bad thing about highly conductive additives is that they bond like superglue to metals after long exposure :/
I'd love to see the long term results with using this for a few months and if any issues come up.
I can't shake the feeling that it'll gunk up components over extended periods of time.
Hopefully I'm wrong. Because it DOES look cool in a custom loop.
Yep will be pleasantly surprised if there isnt a major downside, from the universe's pain in the ass rules n laws.
It does look like the graphine comes out of the suspension pretty easily. Noticed it when he was pouring out of the glass into the fill port.
It may not sand down oxidized material the same way vue does. Depends on graphenes hardness I suppose.
of course!!!!!
Graphene's hardness is pretty low so optimistically it won't grind up components, while graphene is electrically conductive it seems the suspension limits that to something similar to salty water or comparable cooling solutions. My only worry is it clogging up the impeller in the pump or the micro-fins in the cooling element since it seems to only barely be in suspension. A longer-term test would be great to see because it does look amazing even if you ignore the marginal cooling efficiency improvements.

I didn't watch the vid, but there is a product called Water Wetter, for automobile cooling systems that actually does enhance cooling. A magazine test said 2 bottles, instead of the 1 recommend on the label, actually increased cooling.
So, I bought a couple bottles and tried it. Sure enough my coolant temp dropped about 5C. During the summer, I ran mostly purified water with a couple bottles and it worked with typical coolant or plain water. I'm not sure how compatible it would be with pc liquid cooling parts and you'd have to refigure the rate of 2 bottles to 1 gallon of water for your reservoir, but the product did actually work.
3:55 open the fill port before the drain port so it doesn't come out so slowly
i love the channel now being variety in hosts nowadays, ik the boss is on a vacation but seeing this kind of direction of the channel is going is wholesome, being more like a team.
I wonder how the graphene particles affect the inside of the tubes and pump over time... Like does it scratch up/cut the inside of soft, hard plastic or rubber tubing?
Was wondering the same thing.
I imagine it doesn't. Graphite is used as a lubricant and graphene coatings are used for abrasion resistance.
I'd be more interested to see if it gunks up the microfins over time or if it foams up in the pump and kills that prematurely.
@@honeybadger6275 Exactly, 30 minute tests for a new type of liquid are almost useless.
@@honeybadger6275 yeah i don’t even give a damn about its „superior performance“ either. Just call it fancy coolant and people would still buy it all I’m concerned about is that stuff coming out of suspension literally everywhere constantly and forcing me to clean out every single component of my loop regularly cause that’d just be much more of a pain than fancy looking coolant is really worth to me
You should do a long term (6months or so) of constant use with a heavy load put on for like 3-4 hours a day to see if the heat causes the graphine to solidify to cooling fins in a cpu/gpu water block and since its more viscous and heavier per millilitre than distilled water and see what wear/flow it does on the pump

Can we see a long term test? I want to know how the particles would drop out of suspension.
been using my stuff for over a year and is still working normally, leaves less residue than some dyes and all opaques.
@MrPruske My guy coming back to answer!
Id like to see them try the automotive coolant additive called "water wetter", they claim up to 20°F cooler temps when used in a car.
the issue is the temperature delta. In a car the coolant is around 100c (212f), and ambient air is going to be, let's say 25c (or 77f). That's a 75c (165f) difference between the coolant and the air you are trying to dissipate heat into. In a watercooled rig what's the delta between coolant temp and ambient? 10, may 15c (50-59f)? There's just not all that much improvement to be had from the coolant itself. Even differences in the radiator itself are going to be minimal with those kinds of delta numbers.
I'm sure water wetter would help, but the difference it will make is going to be very minimal. If we want to see significantly lower core temps, we need to either improve the thermal conductance of the die itself, or go sub ambient.
Iirc, the water-wetter helps by preventing localized boiling at hot spots in the engine block. If your die never gets near the boiling point of the coolant that's probably not benefit to you.
As the other comments say, I don't it will really do anything or something significant, but, "this is LTT!" (Read as in "this is Sparta!") So yeah! They should do that video Ltt style.
Or Engine Ice
Water wetter will not make you engine run cooler, it raises the boiling point significantly so you can be safe at the high temps you see at the drag strip. IIRC it was meant to be added to engines running straight water. If you have antifreeze/coolant already it will do nothing they aren't already doing.
Seems like a very cool fluid!
But im also very interested in a long term test vs. a „normal“ coolant to see if there is more or less abrasion on the coolers and if there is more or less residue from the particles falling out of solution.
Evaporation-rate shouldn’t be significantly changed vs. normal coolant or distilled water
and Evaporation-rate is also dependent on how airtight your loop is.
For the next edition of Sketchy Heatsinks, they should try to make this with graphite powder and water, and see if it does anything. Or, make a heatsink out of graphene sheets
Curious if the graphene in this liquid could also offer a potential lubricating effect on the pump or other parts of the system, judging from the lubricating properties of graphene and graphite.
Electrically conductive doesn't sound optimal for PC cooling. Even if you clean a spill/leak you may leave some electrically conductive residue.
A non conductive fluid will pick up contaminants from the loop and become conductive fairly quickly anyway.
Even without leaks, imagine leaving this liquid in there for couple of months, the cleanup afterward would be a nightmare i imagine.
yeah that and the eventual clogging and gunk that will for sure accumulate no thanks staying with clear liquids
@@rb30e perhaps, but can't be as conductive as the most conductive material discovered so far (graphene) according to the video.
try watching the video
WAIT A MINUTE.
If the previous coolants had that "layer developing" property, it's possible that the protective layers those formed were degrading the potential performance of the suspended graphene particles.
Just a thought.
That wouldnt be the case for the 2nd test, where there was just water in the loop beforehand.
@@joshuaford4460 The second test was the one that showed actual improvement. There might have been something in the first tests other coolant that interfered slightly.
“Layer developing” because a multimeter have voltage across the probes when measuring resistance, essentially electroplating the probes.

Place a small, spirally bent wire into the drain, facing downwards (with a parabolic curve if you have the pipe sideways) and it should do the trick, just make sure the wire is somewhat same size as the drainage pipe. The draining stream should follow it.
I thought after you said "We're gonna test it out" you were going to drink that 😂
When comparing keep in mind your cryofuel was used. It would have picked up ions over it's life in the loop. Fresh fluid might be less conductive. Same goes with water, after a while of running in a loop it will pick up ions from the loop components.

Not everyone on youtube is 14 years old.
The bigger your radiators are, the less temp-difference you'll see... It is better to invest in a bigger radiator.
This kind of fluid is only useful if you have small radiators en high temps!
That might have been the most engineers-i-need-your-help thing i've ever seen.
That is the complete situation that it needs to be, but instead we're having a meeting with 12 people (of whom 8 are completely unnecessary or even remotely close to the problem)
6:03 - 6:25 This is what it could be like, this is my heaven
I wonder what happens to the fins on the pump after a few years of running what's effectively nano-scale blades of carbon?
Also I would highly recommend against touching this stuff, being 1 atom thick, it could slice through anything from cell walls to DNA.
it isn't really just 1 atom think, it's multiple layers of 1 atom thickness. do you believe you'd be able to hold any sheet of 1 atom thick material in your hand like that without tearing it apart?
@@moos5221 It's a liquid. You can't hold it in your hand at all. Stop pretending the sheet he used for demonstration purposes is the fluid going through the pump.
"slice into it like butter"
>literally folds on itself
._ . yes anyway here's a segue
it wasn't, that is just an optical illusion
To be fair butter doesn’t cut very well. It’s just not sharp enough.

Alex: foam is bad for ur computer
Also Alex: *proceeds to pour foam into computer *
So u guys need to do this one. Why don't we try vehicle antifreeze as the coolant in the loop after all it is a substance chemically engineered to transfer heat well. Among also a bunch of great properties low freezing temperature. ...
a large heat capacity and thermal conductivity;
low viscosity and density;
chemical neutrality to construction materials;
chemical resistance and harmless;
low cost and availability. Final point it's literally made to run through radiators. If you guys don't do it I eventually will one day myself and probably just leave it as my coolant unless things seem like they are negative. But I have high hopes. Hit me back with a shout out cred if you guys try this one.
