Linus, I just watched all 7 of these video's, and subsequently wanted to express something: although your vision/idea didn't exactly work-out as planned, I still find it very admirable you had the will-power, dedication, and focus to finish this mammoth of a project. Honestly, I think this "failure" might have been one of your most impressive builds ever. Because, I KNOW I would have quit in video 2 or 3, and just would have decided to have each PC run on it's own closed-loop.

[@MrTwisted003]

Here's where you could've made it functional and worth it... 1) First, no copper pipe. Use PVC. Much easier to work with and less overall corrosion. Growth is another thing, see #3. 2) Second, it would've helped your pumps quite a bit to not have to push so much water up so high (the gravity force of the water going down the other side does not negate this). Bring the pipe down below the [electrical] plugs. Also the long pipe leads that connect to each station should've been much shorter, which would've been if the main pipes were lower. And don't forget, that the main pipe also should've been a size or two bigger than each terminal size, to optimize the flow rate throughout the system, preventing any one system from choking on a lack of flow. Then each system would only be responsible for pushing fluid a short distance with less restriction. 3) Third, I would've used a plastic tote/container (even a glass tank) instead of a metal reservoir. It's much easier to rinse, clean, replace, and/or top off (evaporation, cause not sealed). It's also easier to check on and add your additives when needed, not to mention easier to just refresh the system as a preventative measure. Make sure this IS placed at a higher elevation than rest of system if not sealed! 4) Fourth, I definitely would've removed both windows (they come out of the frame easily) and created a box for the radiators to fit within the window frame. Very easy to then connect a box fan to just push hot air out, or reverse it to warm air blown into the room during winter. Hell, I would've even opt'd for an automotive radiator for this job...cheaper and more volume and air flow. Final, yes I know this is an old video, but who knows if you guys will ever try this again, properly, for an effective cooling solution. :)

[@Coderjo.]

Additionally, the far end of the loop should have had the system on tees still and then the cold and hot lines of the main loop connected with a smaller size pipe. This would have allowed the main pump(s) to push the air through easier. at each system, the air would rise to the main loop pipes, and then that would be carried through the connection at the far end.

[@CreidDesmodus]

well said mrtwisted, the box fan in the winter is a really interesting idea to... i was thinking the entire time watching these videos about them just usin a vehicle rad and fan (or simple box fan)... probably wouldve been easier/cheaper/and just as, if not, more effective

[@stephanweinberger]

Yes, the reservoir should have been mounted higher than the computers and the distribution pipe at the bottom of the wall. That way the pumps would have had much less work to do (in terms of height as well as flow resistance, as the piping would have been a lot shorter overall). Plus: add a vent valve at the highest point in the loop. And good point to use a car radiator (and a proper fan).

[@RicardoSchaal]

They could also have done a mix: one copper pipe and one insulated copper (or C/PVC) pipe. By doing this: - In summer, it wouldn´t heat up the room; - In winter, they could invert the flow, so it would indeed heat up the room; - It would dismiss the extra radiators over the PCs. What I just didn´t get it is why are the pipes at so high level? Couldn´t they be near the ground or a little bit lower than a desk height? That would have saved: - Around 1/4 of pipes; - Pumping; - Water and additives; - And it would also heat up better the room in winter.

[@isaackarjala7916]

I think putting a liquid-liquid heat exchanger between the individual computers and the shared loop would of been good.

[@alanbrown397]

Whilst you might call it a fail, the noise win is probably worth it alone, especially in a room full of workstations. Yes to other commenters: Whole room AC works fine in a server room., but the average server room runs at 85-90dBA and is NOT a pleasant working environment. If you can put the noisy bits outside or in an acoustic cabinet without overheating them, then its always worthwhile. Comments: 1: Contamination/corrosion: This will always happen due to dissimilar metals in the blocks and suchlike. You _need_ to have sediment filters and cathodic protection in the loop from day one. Drinking water spindown filters are cheap and readily available.Massively oversize it to reduce flow resistance. Couple with something like a Lakos twistiiclean to take care of the big bits and you'll probably never need to change it. 2: Bus vs spur piping. Why are these the same diameter? You should be using larger diameter on the distribution piping to reduce flow resistance and turbulence effects at the pipe junctions. The higher temps you're seeing at the end of the run is because of that. 3: Definitely use PVC or some other kind of insulated piping. Butynol is easier to work with and more than adequate for the temperatures involved. There are pressfit and crimp connections for this kind of pipework. Pretty? No. But to be honest, nor is that copper piping. Put it in some trunking. 4: Get rid of the opaque dye. if anything goes wrong you want to be able to see what happened and inspecting for gunk is much easier if the medium is transparent. UV-reactive transparent dye works well for leak detection. 5: The outdoor unit will be more effective if you arrange a recirculating waterfall/mister on it (adiabatic cooling). This assumes you don't mind the water bill but it's still cheaper than active cooling systems. if you go for this, make sure you have a uv steriliser in the waterfall loop (legionella is nasty).

[@andrewhigginbottom6525]

The heat was taken out of the computers and radiated into the room through the wall of the copper pipes. So basically you took the pc radiator and fixed it to the wall, hence the room temperature didn't change. To get the heat out of the room, you needed to insulate the copper pipes so the heat would be shunted outside.

[@RenegadeenergyincHome]

Pro tip on using IR thermometers: Put black electrical tape on the section of copper piping where you want to take a measurement. Set emissivity setting to 0.95 if adjustable. Wait 15 minutes, and then take a reading with both laser dots and the space between them over the taped area. This will get you a much more accurate measurement. Or, use a contact thermometer.New copper is highly reflective of infrared energy, so the reading you took in the video is a temperature blend of the actual pipe, your IR tool, the wall, the ceiling, your hands, and your face.If you try this build again, use PEX pipe next time. Have to admire the effort though you put into a poor man's CRAC unit (Computer Room Air Conditioning).

You need to put insulation around the pipes to prevent the heat from getting into the room. I work where we have lasers that generate a ton of heat, and they have a massive watercooling system and they put insulation foam on all the pipes.

[@spokehedz]

They said this in the video, but you should use insulation on all pipes anyway, if you don't want to have the heat in the room. It's cheap, it works, and it really does help out a TON.

[@Ultrakillerism]

+Alexander Borsi Back then one of the guy's dad did the piping, first thing that popped into my mind when I saw the exposed copper was "yep, this will totally expel heat back in the room". He gets points for trying, but, like one guy said, he should have went to a data center to check the latest and greatest in cooling options.

[@emremutlu44]

+Alexander Borsi Yeah, was seeking the comments to find this answer :) Copper pipes may be good for a heating system to heat the whole room though, it only looks cool :)

[@bunnywarren]

+Alexander Borsi They probably have a mix of metals in the system which leads to corrosion, especially if they are using water. Water cooling kits use plastic pipes because they flex and don't corrode. They also use a glycol-based coolant with corrosion inhibitors to prevent fungal growth.

[@gamloeader]

+Alexander Borsi the insolation would keep the heat inside the pipes...water wouldnt cool anymore...CPU would stay warm room would stay cool...it would be the same as just turning it of XD

[@tosgem]

Should try wrapping all those copper pipes in insulation to stop them leaking heat into the room

[@danhealy79]

+tosgem You do realize that wrapping the pipes with insulation will heat up the water inside the pipes, thus negating any kind of cooling to be done.

[@josephjack254]

+Daniel Healy thats what the radiators are for...

[@Vincent_Beers]

+Daniel Healy You wrap the hot water out going only while it's in the room. That way it radiates outside instead of indoors. You wouldn't need to wrap the incoming "colder" pipes. But still, the easiest option (as he points out) is simply air conditioning. Individually water cooled systems can dissipate enough into the room (if their radiators are large enough) to do what they are trying to do and then you only need to move the warm air out which is far easier to do than moving the hot water around long distances.

[@danhealy79]

***** insulating the pipes keeps the heat in, heading up the water, lowering the amount of heat able to be transferred into the water and having a higher temperature at the CPU.

[@tosgem]

+Daniel Healy The objective is to keep the room cooler. This is done by placing the radiator outside of the room so that all heat transfers happen there. By having the pipes exposed, not insulated, the pipes transfer heat into the air in the room instead of transferring outside via the radiator. Yes, the pipes would be cooler if they are not insulated, but only because they are able to transfer their heat into the room. You want that heat trapped in the water and pipes until it gets out to the radiator.

[@vegardjohannessen3009]

[@jorgecosta95]

Only math can tell us that, don't forget that those are two powerful pumps and since pipes run no insolation, the heat gets trapped inside as well.

[@Smys3lf]

Pumps will never use as much electricity as an airconditioner. The airconditioner efficiency is about 350w/kw.... mean 1/3 of cold for 2/3 of warm. In fact the idea is not that bad, it surely need some improvements.... coupled with a small airconditionner (as the room is small) it should work just fine. Where a much more powerful a/c would be needed without this installation. Question is: do they really need to save power...???

[@davidcox2459]

So your intake "cold water" is 29.7°C (85.5°F)? Well there's your problem!

[@PHUSII]

David Cox the radiators cant cool the water lower than ambient temp so what is your point? that was the temp outside where the rads are...

[@chadkameda565]

+PHUSII - It's not the rad, it's the CFMs of the fans. He used computer fans for a job that required something with a much higher output. Believe it or not, but you can generate temperatures approaching 5 Celsius with the right fans, using water as a coolant. Build an inefficient system, and you get an inefficient result. All it takes is one thing to not do it's job correctly.

[@beanacomputer]

+Chad Kameda I'm curious what would happen if you included a compressor in the mix somehow (i.e. second cooling loop for the the rads.)

[@chadkameda565]

bflet12 a compressor is used for gas refrigerants, not liquid ones. Partly to house gas in a compressed form when not in use, but also due to the nature of how a gas refrigerant works in a cooling system. A gas cooling unit has 2 rads, one is called the evaporator, and the other is called a condenser. By using the condensing and evaporating functions of the gas refrigerant, it absorbs more temperature, as well as expels it. Remember that the rads for this are assisted by fans, which is actually where you need the fan on the cold side to Pull air through the Evaporator Rad, not Push, otherwise you just push the temperature back into the space you want to cool. The Condenser Rad then has fans that Push, and not Pull, the temperature out of the gas. The compressor then takes the cooled gas and condenses it closer to liquid form, so that it once again benefits the absorption rate of temperature when it re-injects it into the Evaporator. The size of your Rads can certainly make a difference, but the efficiency of your fans is also important. When the fans you use are for a system to remain at room temperature (or ambient), then that is what you shall receive. You would actually need to crunch the numbers for total line length, refrigerant, rad size, and fan CFMs. more fans is not always more efficient, the important thing is how much airflow there is over the looped lines in the rad. Less airflow, less temperature leaves the line by the time a full pass goes through the rad. Hopes this explains.

[@beanacomputer]

+Chad Kameda That's a nice explanation, but it has nothing to do with what I was talking about, which would be using a second system to cool the rad they already were using. I'm not under any sort of delusions as to the effectiveness of such a setup, but their whole-room system wasn't very well-planned in the first place, and it would be funny to see a refrigerator ripped apart and hooked up to their radiator.

Definitely a good learning experience. If they'd actually use the heat from the computers for heating the hot water used in the house - for washing clothes and shower and such it might actually have a payback, also heating other parts of the house during the winter - water could be diverted to reservoirs / heat exchangers in other rooms.

[@moonlightaffairs]

Linus, i admire your adventurous spirit on doing this project. like some guys said in the comments, insulation for the pipes will prevent water from heating up the room before it gets pump out of the room. another thing is the power of the pump, should get a stronger pump since beginning of the project. This actually involve calculating the pressure of the loop before getting the pump. lastly should get a proper radiator, hook the loop up to something like a window unit air con radiator and fan which probably more effective and suitable for outdoor work. well, all on hind side and lips service.

tubing and quick connectors. Keep the system as horizontal as possible, eliminating as many level changes as you can. Use a 5G bucket with a pond pump in it and put algaecide or bleach, etc. into the water or use pure coolant. Keep runs as direct as possible. Install radiator as close to room as you can, use a shade awning to keep the sun off. Tint the windows to block sun into the room. You can probably put the pond pump and bucket in the room in a corner, perhaps inside a rubbermaid tub for peace of mind. Keep it on the same level as the tower connectors and radiator. Free dump the hot water in the radiator, then into the bucket, but pump it back from the bucket to the computers. The height of your radiator should be your maximum rise in the system. Put the pump level with the bottom of the grid. Rent (or buy) a scaffold to do the work on the wall, it's worth it.

Came across this video series from a reddit comment and very glad I did. Very informative and seemed like a fun project. Unfortunate that it fell apart as I was right there with you in you enthusiasm for this project to be an alternative solution. Thank you for sharing.

[@haifishtime]

Why dont you just put your PC's in an other room. Sure a bit of cable management but no noise, no heat!

[@tokeeptrackofrandomsubs5899]

haifishtime It might be a bit troublesome to get long extension cords for high bandwidth data input (consider that it's an editing room), but yea that is probably more doable for sure. Assuming that data will go onto the fileserver and they'll be working from there that should not be a problem other than finding some convenient way to get the data onto the network. Then getting some setup with forced ventilation in the room with the hardware (or air conditioning, not too familiar with what is practical in the climate) would get the job done keeping both heat and noise out of the places where people are. The only thing I'm not entirely sure about is what the practical maximum length of USB 3.0, display cables etc are before data integrity starts to become an issue. This might need some fancy solutions ;)

[@quadrplax]

ToKeepTrackOfRandomSubs Um, are you thinking the 10gb ethernet would be the issue? That wouldn't be any different, and ethernet cords are designed to be long. All they would need is some 25ft HDMI cables and USB cables with repeaters

[@tokeeptrackofrandomsubs5899]

***** Well in that case it should work, I don't keep track of all the details on this channel lately. I wasn't sure about the network and fileserver capacity. In the case of high resolution footage that'd be edited on the PCs first and then the final product gets archived I could see issues happening with multiple people using a lot of bandwidth. But since you mentioned they are using 10 gigabit I'm assuming it should be technically viable for the network to handle the load. I expected potential issues if they had to first get the data onto the PC to process it and then store it on the fileserver. But with that kind of infrastructure you could easily put an "upload station" in the room that is fairly low power and just automatically grabs whatever you insert into it to a place on the fileserver for example to then work with it. That'd still leave a fair bit of heat being generated in the room though, computer monitors, 150-200W per person sitting on a chair (if I remember the guidelines I read up on ages ago perfectly). But Linus already stated their new office will have AC and I wouldn't be surprised if the editors each get some extra space compared to that setup. Many people in a small room without active cooling/ventilation will always warm things up, its what humans do by being alive and having a regulated body temperature. But in a larger room with some kind of ventilation or air conditioning its much less of an issue.

[@quadrplax]

ToKeepTrackOfRandomSubs It seems that the main advantage to this is noise though, and they could have a silent editing room, and also overclock their CPUs and GPUs more since noise isn't an issue

[@harzer99]

haifishtime The real question is, why they dont work via a remote desktop. With the server being in the same network latency is pretty low and you can use all of the computing power of the server on one machine.

[@thequalm9968]

Ok, some tips from a former plumber that runs water cooling on my computers. 1:st Hot pipe should ALWAYS be upper pipe and not under the cold pipe, otherwise the hot pipe heats up the cold pipe. 2:nd in order to get a cooler room you need to insulate the hot pipe to get the maximum amount of heat out of the room, otherwise the hot pipe will heat the room. What you also can do to maximize cooling is to run moisted radiators outside, moist makes cooling more efficient and since they are outside it won't matter to the environment. How you can fit it to your system is up to you to figure out.

[@theformulaguy3620]

This was sofar my favorite of all the LTT video series, although it was not deemed a success I feel with some improvements it can be a great system so this project has inspired me to move my office and studio to a single water cooled system from the PC's right down to the amplifiers ... I am major stoked to begin!! Thanks for the awesome video series I have gained so much valuable insight for my own build.

15 years ago in my old apartment, the kitchen and bedroom shared a wall. I pulled out an old ½ size freezer from the kitchen and uses that space for dual servers. I just put the motherboards on the opposite walls in there. Then I made it accessible from both rooms using doors to be able to service it. In the bedroom I had a desktop with just a keyboard, mouse and monitor + speakers. THAT was REALLY nice... I had upwards to 21 computers, with 18 as servers.

[@kridocaign5722]

Ok, so, skipping the problems you already realized yourself, here's some highlights of what you did wrong: First: You allowed fluids to mix between loops. Cooling loops inside a computer must be tightly controlled and managed by necessity. You need to control the materials and fluid additives you use to prevent problems from developing. Cooling loops in other systems don't require such tight control due to the fact that they simply don't have the same constraints. Instead of running the same fluid through each system and the main loop, you should have had a heat exchanger as a demarcation point so that fluids and problems were always kept isolated. Second: You ran the lines in parallel. If you had the systems connect to one side of a heat exchanger, that would allow for systems to connect and disconnect without any interruption of fluid flow through its segment of the main loop. That means that rather than needing hot side and a cold side you could have all systems connected in series and only have a single loop. This would greatly reduce the requirements for pressure and flow rate, and contrary to what you may expect it would mean no more than a couple of degrees difference between the first and last system in the loop. Third: You had the radiators disconnected from the systems in normal operation. You should have had them connected to the loop in parallel with the heat exchanger, and used a gang valve to cut off fluid flow when not in use. That would make it so that the ONLY time you would need to touch a system's quick disconnects would be when that specific system needed to be moved. As the radiator would be connected in parallel with the main loop, the only action people would have to take to prepare for maintenance of the main loop would be to turn the gang valve and allow fluid to flow through the radiator. Fourth: You used ethylene glycol. Do not use ethylene glycol. Just don't. There are so many better options out there that aren't nearly so hazardous for human health. Instead, use propylene glycol. It's safe enough that it's approved for use in food processing equipment. Further, ethylene glycol gradually dissolves materials like vinyl, which you used in your loop. Always match coolants with materials.

[@joebonsaipoland]

Having run data centers, I have to just say, WTF were you thinking? Why did you not visit a data center and at least look at some current designs? I mean if you were in a very cold climate, this would be a decent room heating system, but it is NOT a cooling system - by DESIGN!!! Save it - in the winter, you can just open the window and use this 'cooling' system to both heat your room and cool it from the outside air. BONUS - excellent learning video. Points for trying. But I wish you would have consulted with a data center cooling or facilities person first.

[@joebonsaipoland]

***** or cold - all i am saying is, if the goal was to remove heat from the room, make the cooper runs as short as possible. Now, you could insulate the pipes with the cheap foam, form fitting, pipe covers. That would prevent some of the heat from being released into the room. One other question? What intensive 'graphics' are these guys actually doing? Have you seen their videos? A GT120 could do this and the heat problem goes away!!!

[@NTDang]

+joebonsaipoland i think it was more hey we can do it why not? more then actually going after the goal of cooling

[@SianaGearz]

+Philip Danzinger Oh it'll cool great, but then you have a long column of air with a sound source at one end. You have probably created a sharp resonator with a propensity for standing waves. Would be curious to try, but to my understanding, it would be ROARING.

[@no_alias_for_me]

Siana Gearz True, good point. But what about an AC?

[@losttownstreet3409]

air flow management (cool air zone and hot air zone) is not as efficient as a water cooling system I once saw a smaller water cooled rig (from IBM running at 5Ghz; maybe a z196) and it make sense. More processing Power in smaller room, smaller rental fees. The hot water may be used for heating or in other ways. Full room water cooling is a professional cooling system with many difficulties; in professional environments they had a technician. They still use distilled water, but still have to deionize it regularly (they use heat exchangers too). It's not for home use. A 220MW radiator makes a cool winter day's to perfect place for outside party -- even if only 80MW was active ;)

[@BluTrollPro]

Hey. If you happen to read this I have a suggestion on how to increase the efficiency of your system. The copper piping will still radiate some heat into the room, have you not considered adding some form of insulation to that piping so that it carries heat more effectively. My recommendation would be motorcycle exhaust tape as it is cheap and easy to apply.

[@AGamingPand]

really cool I work in a factory were we use a lot of water cooling for molds and machines but it's definitely something more appropriate for much larger systems

[@snowcoalRC]

so many things things that could have been done better: the inlet (cold) copper piping should start with a larger diameter and move to a smaller diameter so all the computers get equal amounts of water. the outlet (hot) piping should go in the opposite way. all the expensive pc radiators, pc fans, pc tubing, and pc cooling fittings that make up the radiator, could have been replaced with a cheap car radiator and large fan which would save tons of money and probably be much more efficient since car radiators are designed to handle heat loads like that and there are less electronics the copper piping should be insulated so it does not dissipate all the heat into the room, defeating the purpose of building the system in the first place an air conditioner and a curtain would have been way cheaper and would work perfectly fine

aggressivli If I recall, the intention was not only water cool their computers but, to cool the entire room as well. With the cool pipes, the heat would be sucked from the air(Or the cold would radiate through the room: which ever way to think about it.), More piping, more surface area, more area for the cold from the pipes to radiate so to say.

[@JGrffn]

Riley P this would be incorrect. If anything, the copper pipes are dumping all the heat they're pulling from the computers into the room. Since the computers are what heat up the room, the pipes ideally should've been insulated while within the room in order to successfully carry all the heat outside and, thus, lower the room's temperature as well.

Back in the early 1990s, I worked at a bank. They had just installed a new IBM mainframe in the computer room. It was extremely quiet, and when they opened a cabinet, all I saw was a huge pump and large water pipes :-) The mainframe was was cooled, and the water was directly connected to the Liebert unit. So the machine got cold water in, and put out hot water (not just 1° tempoerature difference). If you have a room full of editors whose workstations each put out 1000watts of heat, it can make sense to take that head directly out of the machines instead of dumping it into the room and requiring more air conditioning power. (and in winter, you get free cooling if your water loop has radiator outside).

No you don't. Just buy thermal curtains. They're thick enough that they end up trapping the hot air against the window, which will just be conducted out when it cools down.
