Building a Cool Box for multi-GPU-PC's [in function]

[sikotik13]

While far from an expert, I would presume that if you are enclosing the cases themselves inside a larger cooled space, you may be better off to leave the sides of said cases open. This should allow the cool air freer access to the components in general, which would keep your temperatures more even all around, and reduce the risk of condensation. It would be similar to a workbench set up, and probably the closest thing to air-cooling like you're water-cooling (where the real benefit is spreading out the heat so you can cool over a larger surface, if I'm gathering how it all functions correctly).

Just my two cents. Seems like a neat idea

Still figuring things out... and know I am wondering how much air m3/hr would be good to get rid of the heat coming from the gpu's.
I am thinking of 120 m3/hr which is one of the highest standard (for poison gas)...
Which would result in a fancapacity of appr 1000m3/hr for a small cool box (2x2x2m) of 8m3
I have seen smaller server boxes (like a frdige size) with 1700m3/hr though, which makes me wonder if I should aim higher and go for 2000 or even 4000m3/hr?
What do you think guys.
I am not talking about aircooling (with airco system) but just exhaust hot air out of the soace with a fan..

Greetz,

Why not try hooking up a fan, and long enough pipe (high temp laundry exhaust) directly to the PC GPU exhaust? Just see if you can move the waste heat before moving onto the next step.

Right now, you're having a hard time deciding how to get rid of it, and not sure what do do with it. On top of it, you're not so sure which method would work. Right?

If your PC fans themselves could drive this themselves, then many of your questions are pretty much moot since they'd scale their exhaust by GPU usage. Can you double up your GPU cooling fans (on the radiator) in a push pull configuration? Has that already been done?

I big honking fan at the exhaust side could offer sufficient pull if the PC fans aren't strong enough.

I'm saying experiment. See what you can do with what you've got.

won't condensation be a problem?

you cool down the metal parts (cabinet), but there is a lot of hot air inside the case, so there might be a condensation problem i guess, but i'm not an expert.

That's where I'd use humidifiers to capture the condemnation as water and put that water to some use such as storage for non-rainy day(s), watering plants, washing my car, etc.

Today I talked to a wise guy (no, not that Italian kind of wise guy ) with a lot of experience in technical, installations, cooling and as well also with big server rooms.
My solution will be a simply a 3,5KW split airco; not less, not more.
No ventilation to other inner spaces or other installation.
In basic the CoolBox will be closed when full rendering and the airco will easily be able to keep the small space cool.
In Summer I can even open the CoolBox to get aircooling in my working space when it is too hot by sun shining through window.

Condensation will be no problem when having the incoming air not too cold, like minimum 15C or just normal room temperature as 20C. The concept is not letting the GPU make the room temperature (or temperature in small space of CoolBox) go higher then normal, which is appr 20C.

Next plan is timing the build of the CoolBox...
Probably somewhere around summer, but I thnink I won't manage before summer, unfortunately...
So this will be my last summer of working behind the PC with only short trousers and keep on drinking to compensate my sweating.

I will update here when there is something to update for those who are interested

It is really time to build that CoolBox.. degrees of the cou is getting pretty high and another PC has 64C temp on the mobo! And it is not even summer
It is all coming form the GPU heat... building the Coolbox is no garantuee ofcourse, but future will tell if temps will be reasonable then... Nayway... Good reason for watercooling!

Watercooling with external radiators, that you put outside

[Hydra]

Get rid of your cases man! All they do is trap heat. Oh and do look into those temperatures. Most CPUs have an upper temp of about 72C. Intel Extreme processors can go to 100C.

Chip sets though can go really hot. Like 100C or more.

Hi,

I'd say it's a bit of a headache, considering constructions, work etc.

If I were in Your place & would think how to cool something like this..
then I'd probably take slightly different solution:

put waterblocks in every machine, get a simple loop, but then a radiator (&/or water chiller) outside Your main room - You can have one powerful loop to dump all the heat outside. Having quick disconnects & at least basic (one movable set) rads would be ideal if You want to get one of Your machines out =)

It might be just me, so sorry if I wreck Your idea, but building dedicated "box" is a one step back - & it waste too much space..- simple pipe, external rad, chiller & more powerful pump would be the best option in my eyes.

If you're thinking of an air conditioner... listen to Glimpse here. Run a long liquid tube outside the room, and put the fans/radiators there.

I get you point of having the radiator in another room, that would be very efficient ofcourse, related to the watercooled computer.
I do not want to have the radiator outdoors, and I need the airconditioning also for my other two aircooled builds, so the radiator of the watercooling will be in the same space as the computers (Coolbox)
but high to the ceiling close to airco. That is the idea.
The Coolbox does not waste any space, because I need the same space for just having the computers placed. Yes it has a vertcial boxed space and the room 'looks' smaller,
but I rather have the computers close to each other in boxed space then in the open workspace.
The concept is for a total approach of three computers boxed, and not just an idea for one watercooled computer.
I think this might work pretty fine... cooling the small space with airco keeping the ambient temp around the aircooled and watercooled computers low.
Ofcourse practise will tell.

greetz, and thanx for thinking with me
