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

[Seekerfinder]

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!

Hey Rappet,
What mobo you got?

Hi Seeker,
The one that had this temp on the mobo is MSI X99S Gaming 9 AC,
with gpu spaced with one slot open between them.
Why do you ask? Thinking of something?

greetz,

Thanks Rappet,
Just wondering because we got that issue on an Asus board in the office recently with only a Titan, a 780Ti and a Quadro in. We did not get it before with 4 cards on the same mobo. The location of the heat sensor on the mobo would be important in this regard I guess - and they probably vary between manufacturer's & board models. The warning does not report actual temps.

Anyhow, that is why we're creating the GPU Turbine...

Best,
Seeker

Rappet, if You go watercooling, simply drop a ful cover block for this mobo on it (if You can find one for Your model =) might be worth to invest a little bit jsut for the peace of mind (wouldn't do on anything less than X99 mobo, but this system has years of lifetime ahead..& 100-150$ to the total watercooling costs might be reasonable).

Hi glimpse,

The watercooling will be with another PC with mobo MSI X58 Pro-E, but I will take that idea. Thanx.

Now, with aircooling the heat inside the case warms the mobo, right?
But when getting the heat out with watercooling, does the mobo not get less hot?
Or does the power draw heat the mobo anyway, regardless aircooling or watercooling.
When using the triple Z as a slave, not for gaming.. then the mobo should not get heated up when do rendering?
What is the reason that youa re thinking of watercooling the mobo as well?

greetz,

it's hard to tell what is happening, but if You'are worried it's always a way to drop temps down..especially if You thinking' bout loop.

I'm more or less against cooling anything else than CPU & GPU. Watercooling RAM is total waste & then VRAM is waste too (IMHO) if You don't put some insane OC, & last but not least, the mobo..

I'd say TitanZ dumbs some heat inside You case & other parts radiate a bit too..- that's probably the cause, I'd be surprised to see that heat comes from the mobo itself, maybe jsut partly.. (You can always try to google up some issues of specific motherboard to know weak points - that's recomended)

Even if You watercool all cards it's still advisable to have enough airflow through Your case to cool other parts..as not all the heat is transfered out with water..some of it do get acumulated inside the case.

Yeah, I dig everything you say here.

The main reason I will put triple Titan Z on watercooling is to get them all three in one case and have an (imo) optimum build for this case/mobo.
(and this way I can add another Titan Black to the arsenal and reach the 12 gpu limit
(you know.. the '780T one').. I will maintain the airflow of that case, which is pretty well, and I do not think that the heat will be too much to heat up the mobo then.
PS
Another reason is the 30% gain of performance (which will make the triple Z on WC perform like a quad Z on air)
Another reason is the fun and excitement of building watercooling.. still little anxious about it, but still educating myself.

Hi guys,

Finally I started with actually building the CoolBox.
The AC (AirConditioner) is on the wall and ready for its job.

The design has changed little bit and I will make triple sliding glas panels on both sides like this:

Coolbox-v14_160115.JPG

Now the next phase starts building the black 'table', white 'frame' and 'glass'.

I have done the thought exercise of climate, and I already got some good replies in this thread earlier,
but I got confused (and unsure) again... grumble
.. it is about humidity and temps (air of space, air blown by AC and air inside PC)

To avoid damage to the PC (parts) by ESD (electro Static Discharge) the higher humidity is better.
Normal humidity isabout 50-70%. So 65%-70% is a good climate goal.
To avoid condensation a lower humidity is better.
So here we go!?

Now I have found this vid... with AC directly blowing the cold air into the PC.
and Ramone (posted the vid) stated that "As for Condensation???
WONT HAPPEN!!!"
https://www.youtube.com/watch?v=Wf9N7qpwiO0This guy wrote a whole explanantion of how and why.. very interesting
,but all dazzles me to really understand.

I found this graphic of temperature and humidity and I tried to project a glass of beer (condens on it)
and the PC with cold air blown into it (from above).
Let's assume the temps of PC is 40 and the air blown into the PC is 10 degrees
the air blown into the PC must be very dry and below 20% not to cause condensation.
Do you think this reasoning is correct?

Climate-Dewpoint.jpg

Why all this? Well, I try to figure out the risk of condensation of using the AC with my PC's?
My guts say it will not condensate when not setting the AC goal-temp lower then 20 celcius) like in the working space.
It won't condensate inside my PC when having the window (nearby PC) open and having cold wind blown inside, would it?
But my devil on shoulder says otherwise... grrr.

Someone has a good thought about this?

I have found this discussion on overlcock.net about the condensation subject:

I read the thread that you referenced. I reside in the southern U.S. where the humidity level is very high from mid-to-late spring until early fall. I use these small dehumidifiers - http://www.walmart.com/ip/Sunpentown-Mi ... I/10750087 - for small air-conditioned computer storage areas (sort of like your cool box concept). As is the case with my H20 GPU system, these dehumidifiers also use Peltiers. Maybe you can find a similar low-cost system for your region.
