That switch blowing up was a bit concerning, especially since it's a quite high-end Unifi Switch. If possible, please show what happened to that switch and maybe you can find out why it happened
This needs more likes. I'm burning with curiosity
Probably got messed up from the water... wouldn't surprise me
@@c.s.7474you might just be right from the spraying of the loose fitting
Well, it's Unify, not really a Cisco.
Who knows what things still had residual water in them and just connecting fittings was a enough to move it around then fry it.
I like how the water knew not to mess with Yvonne's computer
LMAO
The pool water had Linus' DNA when his Airpods dropped into the pool.
@@patrickjeromeobaldo2450ofcourse he never used the pool since he got it
XD
Wouldn't have been worth it for the water.
???? is she abusive or something?
At this point I'm convinced Linus makes the most scuffed setups on purpose so he can make more content out of the inevitable catastrophic repair video
Bingo!
Yep, the life of a content creator of his size and style
we don't mind LOL
@@BleepBlop-rh9lm No, some of us do mind actually ...
I'm not convinced.
Alex commented on the Floatplane video:-
_Fuses blew due to bad Sata adapters. As for the switch we have no idea what happened, checked the power cable with a multimeter and it was all good. Just replaced the switch and it has been fine_
Most likely the entire cabinet has water damage? During the fist incident I would not be surprised if the water heated enough to be steam, steam rises...
might have something to do with linus unplugging cables
The new video with broken power supply concerns me
It seems he might have problems with return voltage from pumps or something
@@prophoenix212 broken power supply actually happened before this video. They were released out of order due to some important footage being on linus's phone that went for a swim.
@@Spudmechanic yeah I wonder if maybe the power source is cursed?
Who could have seen this coming? Absolutely not me!! As a plumber, he did everything right and didn’t mess anything up. Absolutely no corners were cut.
😂😂😂
I don't know if this is the case but I feel like this was a little sarcastic 😂
@@Rayneswordwell, I am a boiler/chiller installer, and even watching this one I’m still cringing but less so…. I’m all for jank in the workshop. But this is $30k worth of computers and servers…. Why cut corners?
@@Raynesword im not a plumber but i know enough to know that it is very sarcastic 😆
wow, that is some tasty sarcasm! nicely served! haha
I'm actually genuinely surprised it lasted this long
yeah i'd have given it like 3 days
Honestly, i gave it like 6 hours until some rocks got lodged in it, blocked the flow and made it explode.@@ghomerhust
New system looks a lot better. But the manifold looks jank and I don't think he has any sensors checking loop temperatures, pressures and flow rate. Also he would need to slow the pool pump down once it gets cold outside, to avoid condensation inside. Check the temperature of the heat exchanger and set a minimum temperature for it and shut the pool pump down once it is reached. It's very well possible he has done this, but its not covered in the video.
It only took this long because he also soaked his phone in the pool and lost relevant footage.
No "Brian the Electrician-Handyman-HVAC-do-everything-guy" this time I guess.
@@handlemoniumHe moved years ago. This was all caused by Alex and Linus’s reluctance to pay people for their expertise.
At this point, the server setup is sophisticated enough to merit a clearly laid out circuit diagram indicating the currents, loads and fuses. Similarly, a coolant diagram, and a fire safety plan should be clearly visible along with an emergency shutdown switch.
And water leak sensors everywhere
Yes! They need you on staff or something xD
@@walkinmn Yaaaasssssssssssss!
crazy not to have these with his smart home setup. There's like 50 varieties lol@@walkinmn
this guy OSHA's
OUT and IN is definitely prone to confusion. I'd use arrows, and a label next to the arrow to what's on the other side.
It can be interpreted either way. Like if you want to move a meeting "forward" on a calendar: is it happening earlier or later?
Or use flow and return, like you would in a heating system.
Or just use arrows
I like
source - device in - device out - return. Arrows are very important because some pipes can see reverse flow in some conditions so specifically calling that out is an important marker.
From his home automation, to AV setup, to pool water cooling, the next owner of his house is going to have one giant mystery to figure out how it all works.
Will probably be easier to reformat completely
It's the real life version of that Geico commercial with the DIYer putting in a murphy tub.
They won't have to figure out how it all works because none of it be working.
Homeowners should keep a living manual for the next owner. Write down all the workings of the house as you change it
@@shellderpmost do. All the houses I build come with the drawings of EVERYTHING, all of the user manuals that came with all the products, surveys, and any other information. My company builds high end custom homes from about $1M-8M. And there's always a ton of stuff. It's usually transferred to the owner in a large storage box.
The junction section being in the rack is terrifying, pls point it outwards at least HAHA
The legend himself! I would love to see you getting a custom PC from Linus some day. 😅
@@M1tZk1 Would be awesome, but he already has a rather killer setup
It would be cool if you could do some pc based content in the future
Loool I just came here straight up from your BMW M3 GTR update video and the least thing I expected was to find the pants man 🤣
Greetings from Mexico 🇲🇽, love your videos sooo much
I was thinking the same, Linus is just begging for another computer failure because of a leak, especially when the junction was leaking on a couple occasions already...
I don't remember, does he at least have a drain in this room if shit hits the fan and they're not there to handle it immediately?
it's funny because the pool cooling crept into my thoughts a couple days ago and I ended up thinking to myself "you know, if I did this, I'd probably use a heat exchanger closer to the server", but for very different(convenience/maintenance) reasons
Some people must learn the hard way. Others demonstrate what happens the "hard way" so the rest of us can learn without experiencing that pain. Thanks Linus et al!
That silicone isn't going to hold it for ever, i give it max of 2 years.
And you are being very generous
@@rallinrallen8040 i know, i always try to be XD, i think with the rate he is using it, it will take 3 to 6 months max.
In my experience, *et al* is rarely used outside of research papers, so I get a chuckle the rare times someone uses it.
IMPORTANT NOTE: At 5:30 when Alex says they are using “Red PEX” instead of “White PEX” what he meant to say is they are using “Oxygen Barrier/Closed Loop/Radiant Heating” PEX or “PEX-AL-PEX” instead of regular PEX. The color of PEX DOES NOT indicate it’s official capabilities, but is just meant to helpfully color code to keep track of things like which line is hot or cold.
So regular PEX can come in white, red or any variety of colors, but that doesn’t mean it has an “Oxygen Barrier/Closed Loop/Radiant Heating” PEX.
“Oxygen Barrier/Closed Loop/Radiant Heating” PEX and “PEX-AL-PEX”, while typically found in red, can also come in other colors.

This bothered me also! And I'm glad somebody said something. Rather I'm glad somebody that knew what they were talking about said something. I knew what he said didn't make sense, I just didn't know the details so I'm glad you shared that.
Idk who needs this info thx any way
@@Abdurrahman24251 Arguably this info is far less useless than your comment there eh bud?
Every single video on watercooling convinces me that it is not remotely worth the hassles.
Noctua NH-D15 ftw!.
AIOs are as close to that as I'm willing to get. And even then, I picked it over air cooling for RAM clearance rather than cooling effectiveness. All the air coolers I was looking at had terrible RAM clearance.
Ehhhh, if I have a weekend off and the $5000/$10000 to make it worth while that sounds like a fun weekend
i mean, i feel like linus's setup is a bit of an extreme example that no one else is going to come even close to doing lmao
correction:
Every single video on watercooling, done by LMG
Probably already been suggested but perhaps you should fit a few water leak sensors in a few places, at least you might have a chance to save some equipment should something start to leak and get a early warning about it.
If he's using an APC UPS it probably already has the connections for leak detection, not sure how it works but I'd guess it can kill power when it detects water
@@charlesturner897does that not relate to current leakage rather than water?
@@BrooklynRaaage Most of the higher end UPS' have multiple environmental sensor attachment points. So if he can find a 12v generic leak detector then the UPS can power it and relay it to the system, as well as perform emergency power off.
@@MsSgent Oh cool. TIL!
Before the house floods
I admire your perseverance with this project!! It’s been a long time in the making.
For labeling, instead of "in" or "out", HVAC systems label them as "supply" "return" with arrows. Supply means the water is cold. So you label both end of the tube chilled water supply if the water hasn't been warmed by the computers.
yes, in and out needs a reference point. however both ways of supply/return and arrows are absolute and can be understood by anyone
You might want to put a water sensor by those fittings so if there is a leak you will have a kind of warning and a notification
And a way to shut off the pump and put the computers to sleep.
Yeah I feel like sensors and a shut off can pretty easily be hooked into his z-wave smarthome setup
@@___Vortex___they already sell stuff like that for zwave so yeah its a no brainer when the leak can literally fill the room lol
Also should have a sensor to make sure that sensor is working properly.
@TriMMA343 well yeah. At a professional setting. Safe kinda goes out the window for home projects.
I love that you have My Little Pony on the white board paper showing the abstract of the work. LOL
Clearly the problem with the first plan was insufficient ponies. I'm glad to see that this issue was resolved in the second attempt.
Usually when watercoolers leak it’s a small issue, but with Linus, no issue is small
To compensate for his height, his problems are much larger than they should be
I guess he's overcompensating
Yeah HES small 😂
the issue is always twice his size
Except his hight
That fire and the instantly blowing fuses were a bit concerning. Hopefully you get that sorted out before something much worse happens.
Yeah.
I'm thinking he might have a grounding issue somewhere.
Yeah, it will not funny to have video about linus burnt house.
my first thought was if thats PoE and does not have diode isolation - that power cord he unplugged could have been live and grounded to the rack@@The_Keeper
nah, a lot of janky installments and a plastic water manifold in the inside of a rack, full of computer and ups equipment. what could possibly go wrong?
I wish they would have expanded on that. They mentioned finding excess motherboard standoffs under the boards and that seems like a potential cause of short circuits
Two thumbs up for the My Little Pony Friendship is Magic whiteboard
17:32 LMFAO. It's how my family looks at me when I tell my friends "go die" or "kill yourself" for purely strategic reasons.
Linus’s house was just trying to emulate Linus’s ability to break things by breaking his computers
No, this is just a Linus's ability to break things. He supervised and planned the whole plumbing setup
@@kreuner11 fr
For a "expensive high tech house" build series, there is a ton of jank and bad decisions. Can't wait to see more!
These videos are really just a grift. He's getting advertisers to give him free stuff that he wants in his house so that he personally benefits (himself and his family... not the company) without having to actually pay for things, he agrees to make videos to promote the products. Then he double-dips by monetizing the videos.
@@scrazzle you say that like its a bad thing?
@@scrazzleYou forgot the part where the entire house is a production expense. Free stuff plus free house. Gotta love tax loopholes.
Most professional installs are full of jank and bad decisions lol
@@Bob_Smith19 that's not how taxes work
The smart home series and new house series in general is some of my favorite LTT content ever
Sad there's no floatplane extended exclusive on this. Linus's house upgrades are the only reason i would think about subbing. I want to see all the fails and solutions to maybe do something similar one day, or just dream about it...
Leak sensors might be a smart investment... They make rope ones that detect leaks on the whole length of rope, so you can wrap it around a hose or surround a component
A negative pressure system combine with a failure to hold negative pressure may be easier to install and more safe.
@17:57 that's not a leak sensor rope is it? confusing
Now we just has to wait until Linus shows us exactly how his basement has a sudden and unplanned conversion into an indoor pool.
One of those odd Japanese pools that run a slight current through the water, even

@@michael.petraeus that's wat bothering me to, how can you sleep at night with this jank water cooling setup that has an entire pool behind it. This thing has the potential to ruin his whole basement xD
You just need either a button connected to P+ and P-, so it will power it on when the button is pressed, or hook it up to a wireless receiver with a switch in it.
You've got conduits, quick connect cables exist for electronics. Unless I am missing some key information, it seems fairly simple.
I love how people are so used to Linus that no one noticed the MLP whiteboards they were using 😂
I miss the haters.
I was looking for this comment and fount them hilarious xD

I'm a little sad we missed the troubleshooting bits. I really wanted to see what happened to that switch, and same for the fuse that was shorting out.
Me too!
I'm gonna guess it was a ShortCircuit! 😜
... due to water ingress, I mean.
Probably a FP exclusive
I'm sure it had nothing to do with water spraying everywhere.
I agree, I would have loved to see it!
finally the roof radiator from back in the day at the editing room is finally realized....with a pool whoooooo. this is seriously amazeballz. awesome vid but what made that switch give up the ghost? coming soon?
That’s awesome. Been waiting for this end result for so long to see how you did it, I’m in Australia and had a similar idea years ago when I got annoyed with gaming in the summer!
so this pool has killed linus's phone and now his pc and server. The next victim is most definitely linus
Next the pool guy 😉
Linus, you should get a few leak sensors, toss them around the server rack (probably below the manifold) and add them to home assistant. Set it up to text you when it detects water. Just an idea and a little bit of peace of mind :)
>text on water detection
Connect your pump to a smart plug/relay and have it shut down automatically along with power to the pcs?
@pawepiat6170 Great idea!
Don't. "My server room burned down" videos do fantastic in the algorithm
They should also design so they dont need them so much - all leads and hoses should be setup so the bottom of the run is away form the system so drips dont go in. Why arent the systems upside down? Why is there no consideration to leak paths?
This is really basic stuff for even outdoor systems, let alone this.
too bad it's already too late by the time you get the notification
After so many years watching this channel I finally got what's the real scope of life: solving problems you create yourself for fun. When you're there means you're ahead of external problems, unconditioned. And that should be good to feel
Alex is rocking the Edison Motors hat!! Love to see you supporting a great company and a great person!!
I like how this issue wouldn't have happened had Jake's proposal for a heat exchanger last video wasn't shot down 🤣
Why anyone would listen to Alex over Jake is baffling.
why anyone would think it is a good idea to pump that dirty water directly through the waterblock is baffling @@cbob213
Even by Linus standards, not using a heat exchanger before is wild. Especially after whole house water cooling lol.
but more content
It wasn't shot down. If you listened to the podcast you'd know that's what they're doing anyways. Linus is not dumb, he knows that's how it's supposed to be done. That said, he said he chose otherwsie for entertainment purposes.
As someone who watches a lot and always feels kinda dumb with how versed everyone is with computers on the channel, these types of videos make me feel way better. Watching them try to figure out basic plumbing is always funny.
We all have our blind spots
Even with all these the current system looks like a recipe for disaster.
I would setup a smaller tank and move water from pool there and connect all CPUs to that smaller tank(it'll be in the same room as CPUs - with filter & everything). Along with that have sensors and other alert systems set up for that smaller tank.
Even with their current system many things could get wrong depending on the pool status and the weather status.
Using silicone sealant on fittings is a terrible idea. Can’t wait to see how it’ll leak.
@@catriona_drummond I doubt thats the case, If I were a betting person I would bet that even without the cameras rolling Linus would do a temp setup just to get it working, hes talked about having ADD/ADHD a lot, and as someone who also has ADHD, I can tell you that it makes you just go for it when your excited about something, even if you are not fully prepared you just want to get it done in some way, it can always be made better, but just the excitement of going for it is well worth the jank temp setup
@@mighty-roman That is exactly what they did... they have a closed loop inside and a closed loop outside running through a heat exchange. No water from the pool goes to the copmuters at all. Hence the antifreeze in the outside loop, and the bio-cide in the inside loop.
"Basic" plumbing, sure
I love Jake's moment of "oh thank god the computer works" one of those moments you try something thinking "I'm pretty sure it wont hurt it and maybe it'll fix my problem" and then immediately it behaves weirdly and you think "oh god i broke it" and then 5 minutes later its fine lmao. This has happened to me more times than I can count
That‘s actually why I switched from PETG to acrylic tubing.
I had a fan controller failure and my system got hot enough to deform my tubing causing a massive leak during a gaming session.
The melting temperature of PETG is just way too low in case of a failure of some sort.
I love how his goal for automating his house only creates more problems the further he progresses towards his goal.
its the 80 20 rule
@@TheTechhXNo, it isn't.
If i had to explain to you why, I'd start with: the Pareto principle (80-20 rule) means that for many outcomes, around 80% of the consequences come from 20% of causes. From the popular understanding of this principle, this would only mean that as Linus continued his efforts farther past this 20% that achieved the 80%, his efforts would become less effective; it doesn't, however, mean that his efforts would reverse his progress.
Perhaps you could read some of the search results for the "Pareto principle," even if it's just the Wikipedia page. Not that I know much about it: I just know that this definitely didn't fit my understanding of the 80-20 rule.
@@FaZekiller-qe3ufI think they were thinking of the 90 10 rule, not the 80 20 rule. Easy mistake to make.
Proof to why Linus may need a person 100% outside of family , friends and coworkers to tell him what tech he wasting his time on and was never needed for the house
This is the first time one of these videos had a conclusion that was satisfying lol
Alex learning how to properly apply Teflon tape is the most engineer thing ever.
IIRC you only need like a single layer of the tape on the threads. Seems like he might have used a bit much and made it harder to screw in.
Because engineers never know how to apply anything to real world it goes to the tradesmen to be able to do anything.
@@orangerider2827 Yes. That was the implication of the comment. Great job parsing that out!
@alanleuthard7619 thanks for parsing my comment out, which was the entire point.
Anything more than two layers…
The most instructable(and reasonable) part is the teflon how to 😂
What a cool home LAN center. The water cooled server room setup is kinda neat, too, I guess.
Every single one of these videos is "our last set of choices led to a predictable disaster, but we figured it out this time!" Looking forward to learning how this all went wrong (and how obviously, too) in the next one.
Yes, this isn't so much got in a professional as, got some advice from a professional (/got them to do a tiny bit) and then janked up everything else slightly less. Although putting tap water and salts (potassium iodide) in the PC loop? There's most definitely going to be follow-up videos.
Also, they didnt seem to have properly fixed or tested the cause of the leak, namely one system overheating and not shutting down, but rather melting/weakening the tubing. Any pump failure (or other flow inhibition) can lead to the exact same failure mode again
I really want to know why the fuse was tripping and why that caught on fire.
right like how could these things be left unanswered. that was wild.
Yea wtf happened with that ubiquity switch thats crazy
I’m pretty sure the room was hot so the water maybe could have ended up in the switch corroding a connection which led to the fuse popping
same here was so annoying they just glossed by those things
I was combing comments looking for this one. I too want to know why the Ubiquiti switch died and what was causing a 25 amp fuse to pop immediately upon closing the circuit.
Amazin work and a great example of how to use all that heat for something productive. It might be beneifical in the long run though to put some cut off valves into the loops and branches to allow for swap outs and maintenance without having to shut down the house side loop, stick pressure gauges in the loops so you can monitor for leaks more easiliy, and perhaps not mount the distribution manifolds directly to the server rack, just in case and so that when it comes to maintenance and swap out you dont get dribbles near the server systems
They use quick disconnects to enable them to do so without valves :)
the in and out is definitely confusing, since youll be confused weather it is refering to the tube itself or the the block, id suggest just labeling the tubes with the the direction the water flow is going with an arrow
I've never seen a computer produce that much smoke that fast, and I've personally seen our lighting struck PC tower explode in the mid 90s. But there was way more smoke from that 2 seconds of being plugged in.
I've seen a computer literally on fire and it produced less smoke. I half suspect that "smoke" was added in post production for dramatic effect although I can't be sure. I'm sure there absolutely was smoke, I just question if they "enhanced" it for dramatic effect.
Blowing up a large electrolytic capacitor can produce that amount of smoke and given that it died the instant power was applied it wouldn't surprise me if the power supply blew.
it was the switch that died
@@oliverer3especially if it was the switch psu and was getting loaded
Back when CRT monitors were the only thing you could get. I had a new monitor bellow out thick black smoke first time it was turned on.
Just a heads up on the pex being outside you need to cover it, pex degrades with UV.
From what I understand that's much less of a problem with modern pex vs. the older stuff, so it's not as vital. Still probably a good idea just for maximum longevity.
Vancouver gets like 5 days of sun, he's good 😂
Edit: yes, there's still uv on cloudy days, yes, Vancouver gets more than five days of sun, glhf.
I'm pretty sure that the outside stuff is in what was labelled "Pool Shed" in the diagram. I assume they remove the "shed" part to work on it.
@@thentilThere still is UV light even when it's cloudy or overcast.
Edit: and there's like 3 months in the summer where it's sunny in the Pacific Northwest. He definitely should be concerned about it.
@@thentilthats not how uv works
Insurance company:- how did this happen
Linus:- my pool leaked
In reference to the switch blowing up and what most likely happened. You need to have your rack directly grounded with a strap and grounding rod (best practice is 2 rods 16ft deep). Rack power strips and equipment have high leakage current and in turn high ground potential and basically stray power can then discharge to the nearest most receptive equipment causing exactly what happened to your switch. So when you unplug something in the rack any residual power in capacitance gets discharged thru ground and because you yanked from your c13 end and the grounding pin is barely longer than the power pins it allowed the current to discharge into an already charged grounding system it was enough to blow up a power sensitive piece of equipment. Also you should bond the rack from top of rack to bottom of rack with a cable large enough for it to be the path of least resistance usually with a big beefy copper braid cable. Also all the rails (Rails meaning your verticals of the rack and not your slides) should be grounded and bonded with a large strap as well because everything is powder coated with only screws bonding grounds to all the pieces of the rack. Also I know you dont want to hear this but your manifolds should be at a minimum be bottom of the rack and optimally externally mounted. Datacenters spec 12 to 18U bottom rack mounting for "leakables".
With your reservoirs, you should have placed the bulkheads at the top with internal tubes that reach the bottom of the tank. This leaves you without needing to worry about leaking. Plumbing 101. Something else I would do with the distribution blocks is place them outside of the server rack and below your servers (or at least just below if you do keep them in the rack) that way if they do begin to leak in the future you have much less, if zero chance of the water flowing down the tubes directly into the backs of your servers.
With the dist blocks below the servers you'd need to worry about air bubbles resting near the quick connects. But I do agree outside the rack would have been smarter.
Yeah, that just looks like a disaster waiting to happen. I don’t get their design decisions. He spent so much on that house and all that setup and cheaper out on things like the manifolds and mounting them. Better to mount them in their own storage with a reservoir and leak detector rather than waiting them to spray water all over the inside of the server cabinet.
@@michaelkr1 I don't think they are going to have much issue with air bubbles with the pressure that pump was doing, wew
Unless the pump being used is self priming the outlets needed to be at the bottom of the tanks with the pumps bellow to get water into the impellers.
Edit: I guess the pump is somewhat self priming so maybe that would have worked.

With higher temps here in Trinidad ( 35degrees Celsius almost every day for majority of the year) i'm always expecting all those fittings and hoses in water cooled stuff to dry rot. It's happening in vehicles as well. Sigh...just got my first ever Liquid cooling setup and I'm still suspicious.
Be sure to check the PEX piping outside has UV protection.
It definitely doesn't.
I came here to say this. It needs to have some kind of covering over it or it will crack in pretty short order.
Learn from my mistakes this time instead of Linus': I forgot to do this on a porch sink, and had to redo it less than three years later.
The outdoor lines should really be copper. Even UV stable plastic stops being UV stable eventually.

I appreciate the way Alex and Linus are like "I bet a pool would be able to cool this rack" and then spend way too much money to make it work. Reminds me of a friend of mine who always had crazy involved ideas that would theoretically work and would be cool to show people. Im a fan.
The video makes way more than the investment, obviously, ltt has ran using this business model since early youtube and unboxings
@@dscarmo I agree with that. Having CZcams is what makes this viable, I just mean for anyone who does t do CZcams to do this. It would be crazy
I read somewhere about the fact that water in a pc cooling system needs to travel in tubes that are bend and not in a 90 degree angle. Somewhere along the line of flow restriction and even wearing off on the inner tubes. you might want to look into this, if you did not already.
So happy to see alex is still wearing the edison motors hat.

Linus' daughter saying, "I'm killing myself" was gold in that scene
Kids saying macabre things due to gaming is a tradition. When I was a kid in the 8-bit days my mom and aunt found it amusing when they called us to dinner and the reply was "Yeah I'm just gonna die first!"
Props for the Minecraft Dungeons gameplay at the end of the video I love that game
As a plumber and electrician, I have a lot of gripes with the jank BUT, Linus is 100% living his best life. I love it.
Get some leak sensors in there and tie them into home assistant for notification, and maybe add a controllable valve on the lines too. One of those tubes starting to leak out and nobody noticing (or being home) is a disaster waiting to happen.
"In the past, I have just used way to much compute trying to figure out which way you have to put the stuff around." -- Yep, that hit home.
I have no idea what's going on in this house/PC room anymore but I'm here for it
16:55 The cable you pulled fresh out of the wall like that banged against the metal of the rack with at least one of the leads, which still had a charge behind it (capacitor), and put a large current on the ground of the switch.
Had to scroll way too far to find a comment even just talking about this. Thanks for your service
I was wondering if the plug banging against the rack had something to do with it but I know next to nothing about electronics so it was interesting to read this explanation.
Nothing in the video showed that, it only showed him pulling one plug out and right after he had plugged the smoking device in.
@@alexatkin you're right, I definitely missed the cut in the editing the first time. It's even a different unit that goes up in smoke than the one that it showed him pulling out
More like the new cable had the internal wires connected wrong on one of the ends. Linus did mention 'Custom' and we all know what that means.
Should have used PEX-A instead of PEX-B. The expansion connections for PEX-A have almost no flow restriction because the fitting inside diameter is the same as the tubing. An expansion tool is used to stretch the tube and a compression ring. Since it takes a few seconds to return to original size, it's easy to pop the fitting in or slip the tube on then wait a bit. Next to impossible to get it wrong. The tube and ring is constantly trying to return to its original size so it's always exerting pressure on the fittings. If an angled fitting isn't pointing the right way, it can be carefully twisted around inside the tube without causing a leak.
PEX-B fittings have an inside diameter that's smaller than the tubing. The metal crimp rings can be crimped poorly in many ways. The tubing is always trying to return to its original size so it's *pushing outwards* against the crimp ring, the same way water pressure is pushing on the tubing. All that's keeping it in place is the metal ring. If the fittings will be exposed to conditions where metal can corrode you must use stainless steel crimp rings. Otherwise the rings can corrode though then there will be leaks.
If PEX-A gets kinked, simply heat it up with a heat gun and manipulate the kinked area to help it restore to shape.
If PEX-B gets kinked the kink has to be cut out. Installing a coupler* to fix it adds another flow restriction so it's best to pull the whole length of tube and replace it (use the pieces for shorter runs) or cut it off and pull more from the roll, being careful to not kink it again.
*Or decide that the kinked spot is where you were planning all along to install a T.
For redoing connections on PEX-A you use a sharp utility knife and a heat gun. Carefully slice across the ring and heat. Slice deeper until the ring splits - without cutting into the tube. Heat up the tube and it can be pulled off the fitting.
It is not recommended to re-crimp PEX-B. A bit of the tube should be cut off after cutting off the crimp ring.
With either type, if the tube gets cut or nicked when taking it off a fitting, cut the end off to get a fresh end. If the sealing surface of the fitting gets scratched (especially across one of the ridges) it's safest to discard the fitting because it could leak.
So easy to find people who criticize what you did.....So rare to find people who teach you the right way, explaining and pointing out what (and why) you did wrong. Thank you for that !
So why does PEX-B even exist, given how inferior it is to A?
@@sivansharma5027 cost, probably
@@sivansharma5027 slightly higher burst pressure, which is unlikely to happen with properly functioning plumbing, and the crimping tools are low cost. Electric expander tools for PEX-A start at around $400. Manual expander tools cost less but have long levers and can be cumbersome to use and difficult to impossible to use in tight spaces.
arrows on all the hoses... process control uses this as a standard. May want to add flow meters as a way to protect pumps and create an alarm for someone to check system. You could go down a rabbit hole to have this system fully monitored and controlled.
Linus was like "everything's working too well, let me destroy something"
I would have added a pressure valve for the bypass loop that opens if the pressure rises above a set point. This way, if he takes machines out of the loop and the pressure rises, it opens as needed to bleed off pressure.
I'd also love to know what caused that switch to lose it's magic smoke. I'm thinking maybe a spritz of water made it's way up there?
Maybe one of those custom cables was buggered? It only happened when he plugged it in with the new cable, but I'll be buggered if I know what about it could do that
@@mattymerr701Maybe one of the cables had live and neutral reversed or something. That could definitely cause some magic smoke to be released.
It’s hard to tell what happened because after he yanks the cord out like a child would, it cuts to all the new cables connected so who knows. The amount of smoke makes me think the cable worked for a short time and something got super hot. If wires were crossed it would have tripped the breaker instantly with no time to heat up. I’m thinking the active and neutral wires were touching somewhere in the cable and there isn’t any overload protection on that circuit.
@@mitchellwilson12354 could be although being A/C usually it wont matter as much, but if maybe live and ground where swapped i could see that dumping 120v all over the ground plane, i guess it all depends on the PSU that ubiquity switch uses. if hes lucky its just a dead psu, and maybe wont need the whole switch replaced
@@mitchellwilson12354reversing live and neutral doesn’t matter for AC, only DC. But if one of those was swapped with the earth wire it would be an issue.
Love the Edison Motors hat, would be sick to see an LTT collab
Arrows would be the right way to do the tube labels. Still need to figure what happened to the switch that popped too.
They tested it afterwards, and the cable was fine, so they don't know, it died, and they replaced it.
Love the cutting edge PonyCAD software, a must have in every engineer's toolchain
PonyCAD ftw
Around 11:49 they talk about labelling the flow-direction. This comment is soley based on my experience as a Marine-/Operations & Maintenance-engineer, in Denmark, working with district heating, sea water heatpumps and what not, within those categories. Practices vary based on location.
The flow direction is best labelled (example ANSI A13.1) with arrows, description and color coding (hot, cold, in, out etc.). Even on smaller projects like this it makes a huge difference doing the proper groundwork before commissioning, if it ever goes south (probably will, them manifolds sketchy). AND for the love of god, get those manifolds out of the cabinet and put a drip tray under them! Also saw another comment suggesting putting leak-detection on the system, also a very good idea.
Other than that, I dig this project. Its cool, and a very cool way of cooling the rack :P
Just trying to push this to the top
NGL these are my absolute fave types of videos
We need more chaotic Alex!
I would highly recommend moisture sensors that kill the power if they are tripped
The moment itll detect anything, damage will already be done
but contained@@alittlebitintellectual7361 otherwise the limit would be the fuse itself
@@alittlebitintellectual7361 true, but then you can stop any water damage to the house's foundations. If he gets a flood there, it's going to be an expensive job
@@user-op8fg3ny3j there isnt enough water in the loop for extensive damage to the house.
I'd be really concerned about that iodine btw. That's potassium iodide + iodine, it's pretty much taking table salt and going a step down on the periodic table. IE it'd basically be like adding table salt to the loop. Massive potential for dissimilar metal corrosion. Also Iodine itself is a relatively reactive element it may straight up attack your cooling blocks/plating's etc. You don't need anti-freeze but there's other types of algicide and corrosion inhibitor type stuff you might really want to look at instead. On the other hand, yay in 4 months we get new videos lol
water weter would be good its meant for cars when you run strait water but is not an antifreeze its meant for race aplactions where they don't want glycol on the track encase of an incident
Yes those blocks are going to corrode like mad.
I would say that he would be better off with copper sulphate, but that is only if He has copper-based water blocks and fittings. He would be better off however using an all-in-one additive for liquid cooling applications anyway, given that he's got a titanium heat exchanger. This means that he has already got a dissimilar metal scenario in his loop no matter what, so it will have the correct bio sides and corrosion inhibitors already in the solution.
Calcification in his pipes pump and block where the water gets hot or even just slightly warm is going to be a HUGE issue within 3-4 months as well because of potassium added, actually to further expand to this, this entire project failed the moment they didn't even realize they borked it up immensely. That was the moment they filled the loop with tap water and THEN added potassium on TOP of that. What on earth was the idea there, accelerate calcification?
@@grasstreefarmerbut isnt the anti-freeze in the other loop. So that water never comes in contact with the water block
Alex rocking the Edison Motors merch is awesome!!!! They need more love
Side note, I LOVE Alex’s Edison Motors hat!
I will be so surprised if I don't see a video in a month with Linus telling us its broken again
I will unsub when I see that
@@StaticVapour590 ill unsub then resub! with out turning on notifications!!!
im looking forward to it tbh :p
Let us hope
Since when
The results are absolutely insane! Not sure why the skimping on the distribution manifolds though. Would also move as much of the water outside the rack as possible. If you must have it in the rack, put it at the very bottom!
But doing things smart and safely doesn't make it's own content... I mean, how many 'fixed' version vids has Linus milked out of this? If your goose is laying golden eggs, you don't go to the vet and ask them for a 'cure'.
@@twiz66 That is the perfect saying for this.
Coming from a woodworking background, I wonder if a cyclone separator for bigger pieces then some layered mesh for finer pieces could've work... Would it even work for water? It'd look cool at least
Colored arrows. Color for hot or cold, arrow for flow direction.
Personally, I would have liked to see the Water distribution blocks near the bottom of the rack. A leak would just pool to the floor instead of running down the hoses into the computers. In other industries we provide a drip loop and a diversion trough to shed water to where we can tolerate it.
That would be too smart and failsafe. Imagine this was indeed the last time they needed to touch the piol watercooling loop, now where's the fun in that? 🙃
I was thinking the same thing - zero consideration was given to drip paths or having the bottom of catenaries away form the system
I just wonder how much is deliberately jank and how much is actual ignorance, not that they arent smart, just that they always seem to gloss over, or not even think about a lot of shit, again, i dont know how much is like that in order to get content, and how much is them being them
Having said that, i wish i could see one of these videos go exactly as planed and handled professionally for once, because i can see it right now, in fact, im.gonna call it, those distribution blocks/manifolds ARE going to leak and fuck something up, because the hoses are literally guiding the water into the systems lol and ffs, how do you crossthread that one? If you know for a fact those are delicate, like, cmon, did he just jam it in there, tighten it until it feels soft again and then be done with it?
They just replace one kind of janky solution with another 🙃 it's research, except not at all necessary.
But then we wouldn't get another video in 6 months when it fails again
Its nice to be able to live vicariously through Linus and Jake.
Such an iconic power couple
@@guska5523 Just add Alex for the most jank throuple you could ever want.

I'm in love with Alex's hat! Where did he get it from? "Edison, stealing Tesla's ideas"
I remember that someone suggested using a heat exchange and linux was like "Nah we don't need it"
I REMEMBER THAT TOO, I think it was jake
They don't need it. If they had someone who knows what they're doing, this would have been flawless. Instead, he relied on Dumdum Alex, and he ended up with a botched mess.
I've been suggesting it to him for over a year too!
Alex is the epitome of why Engineers suck. He has no clue what he’s doing when it comes to everything he touches.
@@Bob_Smith19 Not sure why Alex is getting all the hate. Linus is the one basically have electricians do plumbing and plumbers do electrical. Alex is doing exactly what engineers do, provide exactly what the client asks for with no regards for maintenance, repair, or longevity.
The hoses from the manifolds should have had a drip loop.... as in the hoses should have gone down below where they were connected to the computer and then come back up again. What will happen with the current setup is if there is a leak at the manifolds, the water will trickle down the hoses straight to the outside of the computers. The water will likely then have a good chance of finding a way into the computer cases.
Linus, there is a local company in my country, that cools of their servers in similar way, tho they use mineral oil, and pump it straight into city´s public swiming pool for heating it up. Would consider somethin like this.. it may leak.. but the mineral oil will not short it
The correct amount of teflon tape is the minimum amount you can get away with. But in a closed look system like this, the correct amount is NONE. Use the goop!
Good to know! I'll bear that in mind for my systems in the future, thanks ❤

Well, it was Luke's dad who ran all the pipes for whole room watercooling. There is precedent.
