Learning about water cooling 780 Ti cards

[glimpse]

now these are nice toys =) with price tag to mach =) think with those Your rig should be capable operating at passive mode =DDD.. there is extra rails to mount fans too - I can just speculate how much of cooling capacity those have =) probably with one of this rad You can easily cool down all GPUs that were mentioned by author of this thread =)

I thought exactly about the same And 1kEUR is not that much for such a beautiful 20kg copper baby.

The 3360 Gigant is what I am waiting for. I have all components for my two 780tis at home ... but the gigant has 1.5 months build time :/

Only 2x 780TI on this 20kg monster?

Yes ... I plan on nicely silent gaming And I was thinking of a third GPU one day.

Yes ... I plan on nicely silent gaming/3D working And I was thinking of a third GPU one day. And: I just like toys.

Noisiest elements in entire rig are pumps and psu. 3360 may cool down 16x or more 780 Tis

Hm, not to inaudible level ... I plan on passively cooling, I have two 180mm Silverstone AP182 Air Penetrator fans on the gigant in the end for emergency cooling Otherwise, I expect it to be near silent. The Pumps are Laing DDC Plus ... I tried them, seating them on a thick household sponge you can buy for a few cents .... they're inaudible that way. The loudest noise I'd figure will be the PSU if you go 3 card ... but at two, the Seasonic 860W Platinum PSU is fairly silent.

voon, that's impressive =) please post Your temps on passive mode from two GPUs =) really curious!

So You get 240 RAD with in with fans, then PUMP/RES combo, from here TUBE should go to GPUs (water blocks). After those I’d put 360 RAD (3x120mm) on ceilings. Mounting fans on top of the frame will give You a possibility to mount quite thick radiator bellow. From this top mounted RAD TUBE would go to first 240 RAD & the LOOP would start again. Simple! =)

Having 360+240 is quite enough for 3x 780Ti - even with OC (& extra performance that comes along) they should run ~60C. It all depends on Your radiators. If You get thick enough RADs & good pressure optimised FANS, noise should be minimised, but You’ll never get throttling down because of overheating..& Your system will be more stable =)

I've looked at the pricing for doing this and it's coming out at just over £500 for the full setup with tubes, connectors, etc. So for this and the other machine we're looking at £1200 or so.

We can build another tower for £1300 and could take the middle GPU from the 3x780 machine and one from the other machine so the cards aren't stacked and they'd still be available for rendering and we'd have another machine for an artist to work on, so it's difficult to justify spending that amount on just water cooling for the first two machines.

Is there a more cost effective solution, like changing the coolers on the cards themselves to improve their performance? I know it wouldn't be anything like as good as water cooling, but something priced nearer to £250 per machine would be more viable?
