I love that I'm seeing this right after Intel released their first consumer Thermoelectric cooler. The results are amazing, I can't even lie. Watched one on a 5950x all core 4.8ghz to 5ghz boost clock at 45 degrees C which is bloody insane.
It's discontinued now.
I had an idea a few years ago, but have lacked the motivation to try it out. You keep the traditional water loop setup including rad, but insert a peltier device into the loop after the radiator. You have a thermocouple on the water block that is connected to the peltier and a humidity and temperature sensor measuring the ambient air hooked up to a micro-controller which controls the voltage applied across the peltier device. The micro-controller ensures that the temperature of your coolant never goes below dew-point, so you don't have to worry about condensation, and the peltier does not draw as much current. There is definitely some risk here of your radiator actually working in reverse and heating the coolant, depending on the thermal output of the system, but if you had a loop that cools not only your CPU, but also GPU and potentially MOBO chip-set (and maybe even RAM - because after all this is a crazy idea in from the get-go), I think there is little chance of the coolant reaching the rad at sub-ambient temperature.

That was not fair, the traditional watercooling solution had RBG fans while the peltier on had non-RGB. Everybody knows that RGB boosts cooling up to 50%
It also increases framerates and improves hand-eye coordination, reaction time, and basic pattern recognition skills.
RGB also enables the ability to download free ram and drive storage

Best troll reply of the day. Well done, sir. Thank you for the giggles.
I don't get your jokes. It's just more load.
I had a friend in high school in 2001 who built a TEC for his Athlon XP system and made a water cooling system using a motorcycle radiator. This is old news to me and people keep trying it. I can't imagine trying to cool off a Pentium 4 system during that era with a TEC without breaking a kilowatt of energy.
I had a CoolIt! cooler (whatever their higher end one was called) back in the day. The design was quite different from this; it was effectively an AiO cooler that had TECs between the loop and the radiator. Worked quite well for several years, up to the point that I ultimately had a pump failure.
The pumps always fail on these units. Im still using a modified FreezeOne that works on modern cpus. Replace the pump, the fan ( 120mm mod ) and the block and you have a great cooler. I ended up replacing the lines with Tygon chemical grade tubing for longevity. For even safer cooling, cover the resevoirs with closed-cell padding to avoid condensation.
Edit: LMG, please read and try this
Try running them as a supplement to the radiator! Connect them after the radiator to see if you can get an extra boost in cooling compared to a standard water cooling set up!!!
Stick one in a reservoir
@@TheVillainOfTheYear one of the flat sides of the peltier needs to be not in contact with the reservoir for it to work. simply putting it in, keep all the heat in the liquid and adding some because the wattage of the peltier itself.
Yes PLZ Firts a radiator and than a Peltier element wound be awsome! and might even be the first "good" Bad cooling idear.
@@testjeaapiel9707 have in flow on that water block go into the Peltier and the out flow for into the res.
I think just running one of those aquarium coolers after the radiator would suffice. Putting a peltier into the reservoir would add complications. It may be better for space. But it's not necessary for a proof of concept. Something custom would have to be designed and possibly 3D printed in order for that to work. For a commercial product, (assuming a peltier helps) it would sound like a good idea though.
32 amps... lmfao...
"Ok alex, fire it up!"
(kerchunk)
(sudden random shouting throughout the offices as power breakers are tripped)
I thought the same, talk about energy efficient that's almost 10x the draw of the rest of the computer! And it probably still won't be enough, it's like launching a rocket; you need more energy to dissipate the energy it uses, then you need more energy to dissipate that energy.
32 amps... at 12 volts, so... 3.2 wall amps. A typical home outlet can handle 15, some 20.
@@jetjazz05 That's still a significant 384 watts consumed regardless of voltage. I can't imagine my fans using ~380 Watts to cool my computer.
@@UltraNoobian Sure, no doubt, it's a ridiculous amount. Really nothing uses that much power besides like a fully operating entertainment system, a computer, some power tools. I've got a fan that uses 384 watts, it can pull all the air out of a 12x14 room in a matter of seconds, so for that to be just a very poor quality cooler... nah. Would probably be more energy efficient to use an ACTUAL FRIDGE with a huge spool of tubing in it lol.
Watts = Volts × Amps
Anyway the reason it needs to draw so much is because it is actually working as a heat pump. Basically all refrigeration are heat pumps where heat is being pulled out of a low energy state (your cold food or room) and being "pumped" up and out into a higher energy state (ambient external air). But in order to do that the pump needs to be powered with equal the amout of energy being moved plus efficiency losses. So if the CPU is consuming 100W a perfect refrigeration system that's 100% efficient would have to consume 100W to bring the CPU back to ambient temperature and even more to get it below ambient.
people will see the decibels and think "wow its half as loud as a jet"
Isn't it a logarithmic scale
@@KatieTheDev
technically Bels are the log 10 scale, and deciBels are 1/10 units of that scale.
For anyone curious, Bell used these units because sound and other forces move through a 3 dimension space with power equal to the inverse square of the distance from origin, so doubling the distance would be 1/4 the power. The logarithmic scale also better represents our sensory perception of sound

Hey can you test the cooling performance of the radiator by itself, against the radiator PLUS one of the chiller elements in the same loop? I think thermoelectric cooling may be a better assistant than the sole cooling power
When your PC cooling requires it's own miniature power plant just to keep the CPU at sub ambient temps.

I have to wonder if splitting the hot, out-loop, and sending equal amounts of water to both coolers wouldn't have worked much better. It would slow the water down while inside the cooler, allowing more heat rejection. Then combine the Peltier water outlets to send a single loop back to the CPU.
Yes indeed. Having the TEC and water block positioned after a radiator would offer some much better results.
Cooler Master V10 Air CPU Cooler had a peltier supporting the otherwise MASSIVE cooler

Bad Cooling Ideas : Using a sterling engine hooked up to a motor to pump the heat out of the CPU.
Andrew Vanderschaaf lindybeige turn you on to the sterling engine?
Stirling engine*
Use the heat differential generated by the CPU to run the Sterling Engine to pump the water to cool the CPU. It's perpetual genius!
@@reeceguisse17 If you can engineer that, that might just work, too. Because it's not "perpetual". There's a definite energy in/out, of the power into the CPU, and the heat out of the heat exchanger.
If you're going to use a sterling engine, you'd have to thank God for it.
Hey,
So I have been messing around with TECs for the last 2 months in my spare time and I have found that "overclocking" (overvolting) the Laird Thermal Systems ET15,24,F2,5252,TA,RT,W6 which is purchasable on digikey for about 60 CAD to around 46v which I found was best for directly cooling a cpu. The power consumption was nearing 900w but with 2 360mm radiators and the water temperature around 30C, I was able to cool i7 940 (yeah I not gonna use this on anything too new) at 4.4ghz at 1.43v while remaining sub ambient. I have already built a few peltier prototypes and I live in Coquitlam, BC so if you would like I can bring them if you would like to explore TECs further because its actually pretty fun for a silent subzero fun time.
Electricity Bill:
*Allow us to introduce ourself*
I built, and still have, my TEC Swiftech waterblock like what was mentioned in the video that I paired up to my Core 2 Duo E6600. It was backed by a 3 120mm fan radiator and definitely got the job done under load never getting to above 80F/26C. The problem was when the CPU idled, the temperatures would drop to about -16C(!!) and I could never insulate my board well enough to prevent condensation from forming.
I don't have it hooked up to anything anymore, but it's a pretty cool trick to show people how fast it'll freeze a wet paper towel.
@@eddiemuller3157 Just add a thermal controller to turn on and off the peltier and keep it at 26C
@hardware fanboi When you care about CPU temperatures but not electricity costs.
Linus has to see this, it would be a great video
The Peltiers becoming an insulator is absolutely true. I bought 2 of them as a kid to cool a CPU and if the CPU gets too warm, they basically become heaters and the more power you dump into them, the more heat comes from both sides…
Soy, it does not work for reduce the heat of a Cpu., why?
@@marioj6330 well a peltier module has a ratio of what maximum heat it can dissipate. lets say if your hot side is on 50 C then the cold side will be 5 C. but attach an radiator at the hot side to reduce the tempt to 25 C then the cold side will be lower than 0 C. now back to your question. it cannot reduce the heat of a cpu because the cpy destroys the hot and cold ratio on the 2 sides of the peltier module. the radiators or lets say heat dissipation system is not instantaneous and not 100% efficient as it can only draw such heat from the source. Thats why when the cpu is running and getting hotter, the peltier follows that hot and cold side ratio but with the cpu running the cold side is 30 C warmer(still increasing) and the hot side is already burning hot 70 to 100 C. the figures i said is just for representation and not its true value if applied in its formulas. but you can get the point of why it does not reduce the heat of a cpu
so, it actually starts cooking your cpu?
With a good insulated heat sink shouldn't it do no harm?

The most badass CPU cooling system I ever saw was a copper pipe welded to a copper plate, insulated with foam, and filled with liquid nitrogen, for the ultimate ridiculawesome evaporative cooler of all time.
People use those things to set overclocking records. It really is nuts. However liquid nitrogen, without some way of returning it to liquid form continuously, isn't a long term solution
crazy stuff.
I also love the immersion cooling solutions by 3m that have come out recently... i think it's called novec. basically looks like a pc submerged in a liquid that's boiling. By following all the bubbles, you can see all the hot spots on the cpu/gpu and memory.
Don't ignore those who immerse the entire motherboard in oil.
@@jackhemsworth7515 At that point you should just stick the whole rig into an oil filled industrial freezer
@@jackhemsworth7515 It is also used for quantum systems and magnets. Generally, you simply feed liquid nitrogen into the system and exchange Dewers as they empty. Liquid Nitrogen is actually cheaper than milk per liter, but is a terrible idea for cooling as it is an expensive hazard to the computers.
I remember seeing my first (and last) Peltier CPU cooler in the Pentium Pro days, which would be late 1995 to 1996... There was concerns and issues with condensation back then, as there was no regulation of the Peltier cooler, so it always ran at full blast, potentially getting cold enough to condense water from the air...right on top your CPU.
The Peltier needs to be PID controlled to maintain a constant CPU temp. There's not really a need to keep the CPU so cold. A proper PID will be able to regulate the peltier to keep the CPU from getting too cold. The PID also needs to be limited so that the Peltier doesn't operate at currents much higher than the COP maximum. That way when the CPU outpaces the Peltier the PID doesn't go past I_max and cook everything.
And that boys and girls, is why we have thermostats!
I love this section of LTT! Alex should do more weird cooling ideas ! :D Amazing! keep it up Alex!
How about; multiple fridges, how much fridge do you need to cool a CPU on full load? :D
....jesus. That Peltier you ordered draws more power than my entire machine. And, I run an overclocked Vega64. Thefuck.
*Laughs in r9 295x2*
I had a machine where i measured well over 500W consumption at one time - overclocked Phenom II x6, GTX295, somewhat inefficient power supply.
I should actually measure my current machine, which is still the same Phenom II X6, still the same Bronze class power supply, but the GPU is now GTX970 with a good bit of an overclock, which shouldn't actually be THAT bad. A coarse estimate told me i can expect 175W out of the CPU package on my current overclock. I think i can do more than 300W at least.
@@SianaGearz Some brave people out there still running Phenom II's
@@technologyanimals Yeah well certainly not brave, broke and indecisive. Phenom II is no longer fully usable. While the performance is still borderline tolerable (but it's been 9 years since it used to be a high-end CPU), the compatibility plain isn't, newer software frequently demands SSE4.2 or SSE3S and those are left missing from the CPU.
But i paid mere 110€ for the CPU new from a store, and it served a fair good while. There was a time a few months ago when all the stores were dumping their FX-series stock and i could get something like an FX-8350 for 70€, but those are gone now, now you'd have to pay silly prices on the used market, completely indefensible. Will be considering a full system rebuild with an older-gen Ryzen. Alternatively i could snatch up a cheap FX-6300 or something - while the performance is likely to be a wash, at least the compatibility would be better and i can probably limit the power draw quite a bit.
I am awaiting delivery of Shenmue 3 and i'll probably be interested in CP2077 and probably Watch_Dogs Legion. Then again i won't pay full price for Legion so that'll have to wait a year anyway. Legion won't run on the Phenom, if all the last year's Ubi releases are anything to go by, and a severe suspicion that Shenmue 3 and CP2077 won't either.

@@mohamedkhan5207 This comment chain describes Apple well
I would love to see a project where you have an array of Tec coolers cooled on both sides by two large water blocks, where the cooling capacity is greater than the max power consumption of the cpu & gpu.
You have the hot side a water loop to dump heat to probably 3 rads each with 3 120mm fans.
Then the chilled side, a water loop to your cpu & gpu.
It seems key to me to have the TEC coolers controlled by an arduino, that is monitoring the discharge cold water temp from the TEC, and comparing it to the local dew point inside the case, cutting power to the TECs when you’re within 2 degrees of the dew point.
It would probably be a good idea to have thermal mass in the cold water loop, for when cpu and gpu ramp up and down. Maybe an insulated LTT tech bottle? Probs wouldn’t hurt on the hot side, but not entirely necessary.
Little things I would then geek out on are the cpu and gpu being piped in parallel on the chilled water loop, with balance valve so you could divert flow for optimum temps between the two.
I’d prob have all the hot flow go through 1 rad first (as it would be at high temp and thus dump heat quickly with the air), and then the second rads in parallel, running at lower temps but having a lot of air to approach ambient. Maybe experimenting with arrangements here would be fun.
But the key part of it all is that arduino monitoring chilled water temps, as to not have condensation on the cpu or gpu. Which I think is one of the main faults with the coolers shown in this video, second only to their cooling capacity being much lower than the max power consumption (thus heating capacity) of the cpu.

@@nmotschidontwannagivemyrea8932 I'd say a TEC is quite reliable as it lacks any moving parts, except the water cooling part of course. It'll probably hurt the PSU like any other component if the peltier module does fail. It has contact with the CPU lid, but not the CPU itself as it's insulated unless you use a conducting TIM.
Next, try a TEC and a radiator in series, because science.
First the radiator hopefully (to bring temps down to nearly ambient, then sub-ambient, so that the CPU is just a bit higher than ambient).
Yea, Please do that :)
doooo iìiiiiiittttt Linus! Alex must put this together! who cares if it consumes 32 amps or 3000 watts, we need to see this!
Yeah . Too many tech channels set things up to fail. Id like to see what it would take to make TEC viable on modern CPUs . Well i know how id do it, i just want to see others use their brains
Something I figured out when I built a pretty decent custom loop with 2 GPUs, a CPU, 2 rads, and 4 inline thermometers in different places: Loop order doesn't matter. At all. No matter how I loaded the system or ran the fans, all 4 thermometers were always within ~.1C of each other. Sure, the whole loop temperature would move up and down with system load and fan speed, but all of them would move together.
So yeah, loop order doesn't matter.
Jeez I remember peltier coolers back pre 2000 to allow CPU overclocking to 200MHz+ :)

Stock up those Peltier resistors, use about 5 one on to of each other, parallel connect them, such set up of dozens is used to create true cryo temperatures
The first Peltier CPU cooler for the PC market came up in the 486 era (i.e. before Pentium). The issue was that the extreme cold could lead to condensation, icing, and even embrittlement severe enough to snap the mainboard in half with vibrations if mounted vertically.
The 1990s were wild; many chips could be clocked 50% above design specs back then.

2 questions. Does anyone know what type of laptop Alex is using, and does anyone know the specs of the rig they are testing the cooler on?
if you were to use a standard radiator setup but use a peltier in series on the return to the cpu would it work better. like passing the pipe through a fridge after cooling

Ok, Linus and ElectroBoom both have a thermoelectric cooling video out within 24 hours of each other. Strange...
But Mehdi is a bit "nerder" therefore no use for 99% of Linus's subscribers aka schoolbois, aka have you finished your homework? aka it's summer mom
Both Canadian?
Linus’s videos are always in queue and filmed WAY before they come out... look at for example...when one of them gets a haircut and comes on WAN and then look wt the most recent video 😅😅 you’ll see the new haircut after 2-3 weeks 😅
You know what else is strange?

My first from-scratch build in 2000 used dual celerons cooled by peltiers. But of course, a celeron 366 didn't put out that much heat, even when overclocked to 600. It worked well, but I did kill a few power supplies over a few years.
peltier chips are good for one things: using a joule thief circuit along with it you can make diy flashlights that are powered by your body warmth. power input creates temperature output and vice versa.
Long ago, a company sold a vest that would supposedly power your laptop with body heat. The vest was just a SHIT TON of tec plates.
@casey360360 I should've mentioned the flashlight it'd be powering up p is not a very bright one, still useful though.
Are you serious about the vest? I gotta look this up lol. I got a feeling It's probably gonna end up with me going down a rabbit hole.

In a sound studio, you can't use either traditional watercooling or fans because of the noise they make. So if you don't have the option of doing your cooling in a different room, then using peltier modules can be a good idea. You could put lots of peltier modules on the outside of the chassis to silently pump heat out of the system and in that way improve the efficiency of the CPU cooler. Come to think of it, I think that could also be used to bring the system down to very low temperatures, since the condensation would gather on the outside of your chassis and away from any electronics.
what if you make a mixed setup?
the regular radiator is mounted first and cools the water so the peltier devices arent overwelmed and the thermoelectric cooling is used to get sub ambient water temps
At least you can use this to get free water from air.
Oh wait...

Where can I buy a compressor cooling kit for my PC? Or a PC cabinet like old good Thermaltake Xpressar with a build in solution?
I used to work at a lab where we used Peltier coolers to chill the CCDs. We did get the condensation problem once, which resulted in some confusion looking at images till someone worked it out XD (they're supposed to be sealed units so water really shouldn't be able to get in there, but of course, it still happens sometimes :P)
Cooler Master V10 had one too! i had a q6600 cranked to the max with one of them and it ran SWEET
Very informative video. I had no idea what a TEC was until today. Thanks for the great video as always! 👍
most car 12V "fridges" use TECs. But they can only do 20C below ambient. Cheapest compressor based fridge I found for a car, was at similar price as my home fridge.
Thanks for making a video of this. I've been wondering about it for more than a year.
Just curious, in keeping with the theme of bad cooling ideas, what would happen if you added the radiator to the loop after the CPU to bleed off some extra heat energy before the coolant circulates back to the TECs. This way you are reducing the pre-cooler fluid to as close to ambient temps as possible before the coolers do their work. I realize it costs twice as much and negates the comparison between the two, but it would be interesting to see just how cool you can get it by using TEC. It would be more like boosting an already capable system than trying to replace it altogether. Also curious what affect you would get from using the TECs in series vs parallel configurations, i.e., running the coolant through one, then the other vs splitting it into two parallel cooling paths then merging them back before they enter the CPU cooling block... you never know, maybe the slower coolant flow through the cooling blocks will allow for more heat energy to be removed from the coolant. Other tweaks, like insulating the cooling blocks and cold lines and having the coolers as short a distance from the CPU as possible might add a little efficiency as well.

"My air conditioner doesn't have [a bluetooth speaker]..."
MY air conditioner doesn't have an AIR CONDITIONER.

@@therealpbristow ahahhaa
for the TEC cooler is important which side you put the fan... because if you put the fan blowing hot air from radiator from TEC into radiator for cooling CPU then we got a problem...
At my previous job we built a railway inspection system with two high-end pcs in a box with water cooling, where the water was running through an industrial chiller. (The chiller was cooling multiple water streams, pcs, cameras, and LED lights) Try that! :D
The logic of this sounds like...
"Let's cool all them watts, by adding MORE watts!"
That's pretty much how TEC works.
I don't want to see that electricity bill which will arrive afterwards...
@@SimonWoodburyForget I guess, but isn't the whole point of an air conditioner is that the reactions that occur outweigh the added heat of its power consumption, if that makes sense? Well, certainly in that it pumps the heat away, so I guess it doesn't outweigh per se. Or does it..? That's interesting and a whole other question I guess.
This almost sounds like you're pumping electricity directly INTO the device that needs cooling. But I guess that's not quite what's happening either the way Alex explained i. It just seems like this whole thing is a waste and that if it ain't broke, don't fix it, you know?
I remember to have done the calculations for Peltier cooling on the late 90's or early 2000's and the numbers get really fastly big. When you use a peltier, you want:
1°) deltaT (hot temp - cold temp) as big as possible.
2°) hot side (and so cold side) as cold as possible.
Then comes the problems: A peltier element can achieve his maximum deltaT when the heat input in 0w. When the eat input match the peltier maximum power, the deltaT become 0°C. It means that a peltier has to be much powerfull than a CPU if we want it to be well-cooled.
So for example a 25W AMD K6-2 from this old times, to be quite well cooled, you need a 80W+ peltier. A 80W peltier means 80W power absorption capacity. And so 80W+ power consumption and eat generation. So the cooling system have to be big enough to evacuate 25 + 80+ = 105+W heat instead of the 25W from the CPU alone.
Also sometimes, a peltier fries. So he become a powerful heat generator, leading to to the CPU to follow it in his death.
Alex's facial expressions at the start were hilarious.

And add it started, I skipped ahead. I'm heare to learn from others mistakes so I don't have to waste my time and money on things that don't work. I actually pay for CZcams to avoid the 2-ad-per-minute nuisance. I'm not here to buy things I don't need.
The TECs can stacked. The TECs give approximately a 30°F difference. So when you run water across 1 and then another, you give it more time to lower the water temp but can never get below the limit of ~30° before ambient temp. However, if you put 1 TEC directly on top of the other, then you can get ~60° drop in ambient temp.
Now try putting the TECs directly onto the CPU (using thermal paste). You can then put a water block on the hot side to send the fan cooling to another location.
You can also use antifreeze in the water which absorbs heat better than plain water alone. There are other chemicals that absorb heat even better but some of those are expensive or they are poisonous to breath (ammonia) and so not good for residential use.
@@SI-GOD this is great info! Do you have a demo? Video? Or web page and pics?
I remember seeing TEC coolers in computer magazines and catalogs back in 1998. They didn’t catch on due to condensation on the cold side. Given the control modern boards have, it would make more sense now though by the time it could have made sense CPUs started making so much heat that TECs couldn’t keep up.
"They didn’t catch on due to condensation on the cold side"
I remember this being an issue, too, and also the reason these coolers fell off the market.
The real issue with these coolers is brainless idiots like these not understanding why they weren't more widely distributed before; that the technology specifically for CPU cooling has been around for over twenty years; that the science is real, and named after a real scientist; that the shit works, but perhaps not with this specific illustration.
Another person who posted a comment to this video, Kyle Quinn, remarked:
"I love that I'm seeing this right after Intel released their first consumer Thermoelectric cooler. The results are amazing, I can't even lie. Watched one on a 5950x all core 4.8ghz to 5ghz boost clock at 45 degrees C which is bloody insane."
Another big issue with this cooling solution is that there are no moving parts, which means the service life is dramatically increased AND it is substantially quieter than a fan! Literally no noise! It'll use more juice than a fan, but you're also not technically losing a considerable amount of that electrical power to friction from the fan blades spinning.
The only thing that matters in a sustained workload is the surface area of the fin stack. It doesn't matter whether you move the heat with heat pipes, water or TECs.
Also the temperature Delta (Fins/Ambient) matters, so if you could have a magic TEC, which could move the heat for free (and brakes thermodynamics), your fins would be more effective and you could use less area.

Is there any benefit of cooling a cpu and gpu below ambient say maybe 10 degrees celsius under overclocked load instead of 30 to 80 or whatever above ambient degrees celsius?
Maybe longer life or better efficiency? I also don’t see the tec’s as stand alone coolers, they are more inefficient than radiators above room temperature, yes, but because radiators cannot cool to or below room temperature, tec’s are therefore more efficient there.
Just not sure if there is a benefit. Also not sure if a better build with tec’s is to use the water cooling blocks on top of the tec’s and cpu to water cool the peltier, keep the size and noise down, as well as get the cpu below room temperature or to put the tec at the end of a radiator loop with some 6 heat pipe tower heat sinks where the tec chills room temp water from the radiator below ambient before it passes through the cpu and gpu and even to cram a peltier and water block inbetween the gpu and cpu to flash chill the water between the systems and to make use of the small size of the modules. Another system is to carry a double stack radiator with one water loop for cooling peltiers and another loop for bringing water to room temp with maybe an electric valve switch to either go below ambient or turn off the peltier and route water from the peltier cooling loop to the central loop when overclocking. Long story short, anyone investing in water cooling isn’t exactly a budget builder and will pay a few extra buckaroos for space saving, lower noise, and looking for whatever air cooling cannot deliver
Also, get yourself a krimping kit, like cheap dupont 2.54mm connectors if soldering is not your thing :p
TECs can be great, when done properly....
Like with my 400w TEC getting an athlon Xp Barton to sub zero temps with a liquid system chilling the hot side. And a second psu dedicated to the tec.
....as you said "in the old days"
Diavuno similar here, K6-2 450 @ 540 MHZ at -20 C using peltier and custom watercooling loop in 1999.
"TECs can be great"
like the one keeping my food cool on my road trips :)
Put a tec inbetween a refrigerant phase change system block and the cpu. It doesnt really work, but thats sort of the point of these videos.
I had a Titan Amanda TEC cooler back in the Core 2 Duo days and it worked pretty well, was just quite power hungry.
Does anyone know any good places to buy water cooling parts for PC in Canada? Seems the cheapest solution I can find is around $650 CAD for whole setup (minus gpu block)

Cool fact: some dehumidifiers use peltier modules to dehumidify rooms as the warm humid air is drawn pass the cool fins the water is condensed and drips into a collecting tray in the bottom of the dehumidifier.
I'd like to see you try this test. In cars which of course use liquid cooling, they apply an additive to the water. The coolant added to engines, not only stop the water from freezing but also make the water more efficient at heat conduction. Would adding a coolant additive to the water in a PC system help cooling?
12:58 _Linus always has a simple solution to complete the loop in half the time. You only get that after years of experience, kids._
Maybe put the radiator on the warm output side of the CPU so the water going into peltiars is a little cooler?
The only thing I have every found them useful for is that when I was a truck driver in the '90s, I had an Igloo cooler that had one built into it that was designed to fit in a specific space in Freightliner sleepers. It worked great. Never found a useful application again. They have a COP of about 2 max if you can find a place to dump the heat away from what you are cooling.
I was researching peltier chips on CPUs and stumbled across an interesting comment (not sure if it was this video or another). Someone suggested using a peltier chip in conjunction with a water cooling system. Instead of applying the peltier to the CPU, you put it on the water reservoir to keep that cool. However, hearing about how peltiers use a lot of energy, I decided to look up ways to control the voltage to a peltier. Apparently, you can't regulate the voltage. But, you could turn it on and off with a PID controller. The PID would monitor the water in the reservoir to make sure it maintained a constant degree. If it went too high, the peltier would kick in and cool the water back down to the optimum temperature before getting turned off again.
Used to TEC cool my Celeton 300A @ 600mhz, wayyy before 2007.
I still have a 300a @ 450
I remember first seeing the name Peltier back in '99 in reference to OCing Slot 1 CPUs
