It's been a long time coming, but after being moved into Linus' new house we are finally making his ridiculous dream come true. We are watercooling a PC using his pool. That's right, even the hottest components like the Intel Core i9-13900K or the RTX 4090 will be easily cooled by the sheer amount of water. But can we cool Linus' hubris? Also, is this actually going to work?

@192347001 9 месяцев назад

As a boiler guy I am happy about this project. For the final install you may want to incorporate a couple things. 1-Get the heat exchanger. For an application like this you almost require it for permanent operation. 2- You will need a expansion tank for the pool/glycol loop. your server loop can be open loop and not need glycol or any real pressure. 3- install a axiom (or equivalent) tank for the pool/glycol side to maintain your glycol/pressure without needing to add back flow prevention. (add a vacuum breaker to that hose connection in the basement) 4- size the pump correctly, unsure of what you have at the moment but a grundfos 15-58 is a good pump for single loop applications without going overboard a 26/99 has better head pressure but has way to much flow for a single 3/4' loop and will kill it's self way to early. 5- I use glycol as a generic term. Recommend getting rid of that automotive glycol and picking up a polypropylene based glycol (with inhibitor) from the same supplier you got your fittings. with ethylene/ automotive coolant leaks pets and animals can die if they drink it. side note you need at least a 20% glycol mix to prevent algae growth but more that 30% you will have to up size pumps to overcome the extra viscosity.

@scottgardiner7418 9 месяцев назад

@@crowman6330 The Loop from the Pool (the one with the Stinky Water) will NEVER be clean (even if you use Chemicals against Bacteria/microorganisms) and you need AntiFreeze (Glycol) for it to not freeze in the Winter. Dirty Water and AntiFreeze are NOT what you supposed to use in your PC Loop. It will block all the MicroFins over time.. Slow at first but the Longer it runs the Muddy Water, the more Muddy it will get and the faster it will block them. The Exchanger is a 2 Path system to split the Loop in 2 Loops, one with muddy Water for the Pool Loop and the one with clean water and without antifreeze for the PC. So it dissapates the Heat from the PC Loop into the Pool Loop and takes the Cooling from the Pool Loop into the PC Loop, thats why its called "Exchanger" ;)

This is awesome! Glad your going to use a plumbing Manifold when you hook up more systems. I would look at your temperature delta for your pool and what you want your server room temps at, for the radiator. A comfortable swimming pool is 80-87 degrees F. Unless your server room is already warmer than that, i wouldn't bother with a radiator. Your water cooling is going to be wicked good in the winter, be careful with the above ground pipes freezing if you have extended cold snap below freezing.

@starbuckqbb2287 9 месяцев назад

Process water engineer here. Whatever filter you’re using needs to have tighter tolerances than the water blocks. A typical 20 mesh strainer won’t cut it. Highly recommend using that heat exchanger with a DI loop for your rack. If you really want the massive thermal reservoir then get a small buffer tank. It’ll be just as effective and much easier to maintain.

Question: It looks like the loops are going directly through the water, but rather embedded in the concrete itself. Doesn't this mean that the heat is transferred into the concrete and then cooled by the water? In which case is there an upper limit on concrete thickness for a project like this? The reason I ask is because I was considering doing something like this, but with an artificial pond instead of a pool. The key difference being that the concrete would only really be used to hold the pipes. The sides would not have concrete walls so above the concrete bottom there would be layers of sand, then a pond sealant, then aquarium sand for plants to be able to grow into. The general idea is that the aquatic plants keep it clean while fish keep it free of mosquitoes. A boxed in area at the center and one edge gives access to it for swimming. So, in my use case, there would basically be about a foot of Earth between the pipes and the water and although the water would be circulating and the sand would be wet I'm wondering if a sufficient heat exchange could occur. I was also wondering if the small amount of heat could be of some marginal benetif to life in the pond in winter when the ice freezes over since the ice would be sealing in warmth. And, on that point, if that could result in a decreased benefit using in winter.

Why not use a heat exchanger to isolate the loops from each other? You could also use 3 way valves to turn off the connection to the pool and switch to another water source in the winter. It would also allow you to regulate the pressure on both sides of the loop; lower pressure in the PCs, and higher pressure in the pool loop.

What you want is a water to air heat exchanger, which is what they do in some actual datacenters. Requires zero modification of server hardware (which is very important) as you're cooling the air itself, not the servers directly. Big reason being, you can't just cool a server's CPU, you have storage, VRM's, power supplies, and various other motherboard components and addin cards that require air cooling, none of which have water blocks. The added bonus is, with an water to air heat exchanger, you gain the benefit of cooling the entire room too, so, no HVAC needed really. Combine that with a very basic PIC and a DC inverter pump, and you have a system that only demands exactly as much cooling as your room requires, so it'll never go sub-ambient and create condensation issues. So, you know, as per usual, Linus had an idea that sounded cool in his head, but in reality isn't well thought out, and will lead to problems down he road (and more clickbaity videos of course). I do hope that he eventually realizes how irresponsible he's being bringing this sort of misinformed content to the masses.

You guys should really do the heat exchanger like Jake suggests. You would have to heavily treat such a huge loop for even a slim chance of not gunking up the micro fins on the water blocks. There is just too many points for potential contamination imo Edit: not to mention, youd also be trusting the integrity of the work from the pool contractors that you were fed up with

@numberyellow 9 месяцев назад

i'll bet money the system ends up as bad off (contamination-wise) as that whole-house cooling loop he built years ago. I really had high hopes that he was gonna do this up right, but it looks like a repeat of the aforementioned large-scale water cooling system.

@NavinF 9 месяцев назад

Sounds like he's using ethylene glycol antifreeze. As long as it's mixed per manufacturer's instructions (unlike in the "whole room watercooling" video where it was heavily diluted), it's impossible for this loop to gunk up. EG is a biocide at large concentrations but feeds microorganisms at low concentrations which is why the old video was a fail.

I really think the heat exchanger is a good idea, in terms of maintenance it would be a lot easier to drain the loop if required, and would also require less pressure load on the components because you wont have to pump such a large body of water

They just pumped in water from the T (or something) in their water main, which is part of their hydronic house heating system. Besides that, how do you think they could accurately measure the volume of the fluid in the loop to mix to required spec? I dont have Floatplane so I cant speak on how long it actually took to purge the whole loop, but ill bet it took a long ass time. If youre thinking about using premixed antifreeze then, I dont think bulk premix suppliers exist.

Linus 1. do a heat exchanger -this will allow you to keep high pressure (pool) and low pressure (PC) systems separate -if done right you can flush the pool and pc sides only when needed 2. do a filter on the pool side only -this will keep garbage from damaging the pump -and filters can release particles into the cooling fluid thus clogging the fine fins of water blocks

PEX manifold behind the rack so you can individually isolate different components and make changes without losing all cooling is definitely the way to go. You also should have gotten a ratcheting crimp tool. Supports more sizes and is cheaper with the ratchet clamps being more expensive, but for how many you are using it would have been better for you.

@fader52 9 месяцев назад

Loved this video. As an HVAC it checks all my boxes. One thing to consider that you may not have thought of though is that in the winter the water coming from the pool will almost certainly be colder than the dewpoint of the server room(~10°C). Those pipes coming in from the outside will be sweating and will get water in the server rack if you run it like this in the winter. If you add a heat exchange put a drain pan under it to collect the water that condenses and insulate the pipes coming from the outside so they don't sweat as well. Make sure that the pump on the PC side of the heat exchanger has enough flow that the heat exchanger doesn't cool the water on the PC side below the dewpoint as well.

@GorgotMM 9 месяцев назад

It shouldn't be that cool. Maybe below the dewpoint, but not -10C. The winters don't get super cold in this area and there will also be a ton of heat pumped into the fluid. I do agree however that in all cases, this needs a low point with a drain pan.

During winter you should create a system that dumps the heat from the CPU/GPUs into your home heating system.

Perhaps the suggestions that you need an actual heat exchanger would be the best implementation to create a simpler closed loop.

I would mount multiple heat exchangers and electrical valves in the lines. Heat exchangers will keep the crap out of the loops and keep the water amount down in each pc loop, making service a bit easier. Heat exchangers and valves would make it possible to shut off pool heating and heat the house in winter and opposite in the summer. If the house has AC you could even dump that heat in the pool too. Preheating the incoming cold water in a heat exchanger before it gets heated in the boiler will also provide 5-10 degrees water temperature to the loop.

Both the AN/UYK7 x 2 and AN/UYK-44 x 2 onboard a fast attack submarine that I served on (in my youth) were both water cooled. However, the water chemistry was tightly controlled to limit corrosion (EAFW system). I would avoid pool water, given it's recommended pH and chlorine levels. Seems to me that an outside heat exchanger would be necessary, to avoid issues with the IT equipment and to limit water damage, in the event of a leak.
