I feel your pain rappet, we've been going through this as well, we have the 780 Ti SC cards and they do run hot. Unfortunately the case doesn't solve it either, we have the Precision software running and take the cards down to about 70%, extra case fans. Water cooling looks to be the only proper solution.

Wise.

I though 'bout the same thing.. & it shouldn't cost that much, pluss You will probably gain more performance too.. so it as win-win situation =)

I've emailed the ekwb people about our build and requirements, is there anyone else you can recommend for water cooling solutions, unless you guys can recommend specific parts we should get?

write exact model of those cards You own =) list other parts like case & so.
ekwb has tool to see what water blocks fit Your hardware =) check that =)

it seems Your cards have ref designed pcb : http://www.coolingconfigurator.com/step ... _gpus=1262
so, there's plenty of water blocks to choose from =) unlike when You have something custom, like STRIX from ASUS =)

as for case You have enough space to play with =) 240mm in front & 360 up top (look for some case reviews what modders recomend & if case doesn't have any compatibility issues =) Then get pair of rads, 5x Slow spinning, pressure optimised fans (like noctua nfp12); pump & res (or combo =) with something like d5; some tube + fittings & You're ready to go =)

Make new thread if You need more assistance & I believe some guys will be happy help You out =) ACX (from EVGA), WINDFORCE (from Gigabyte), etc. are not the best coolers in for multiGPU rigs, plus they throw a lot of heat back into the case, rising up ambient temps & dropping efficiency of cooling that will effect performance & more then likely throttle down GPU's (loss of performance comes along..)

the loop will cost You a bit, but You probably get performance of extra card too, less temperature & less noise too =)

1. Set a new topic - we'll help you with pleasure (look at my signature).
2. EK-FC780 GTX Ti - Acetal+Nickel [3831109868645] covers all pcb which is great for dust removal, unlike short waterblocks. Get a backplate - great investment - not for looks only but for temps.
3. I am afraid your case has not enough radiator capacity. For 3xgpu and cpu I'd go with 2x480 or some 3x3 external solutions - Glimpse please help with the link to it.
4. Great motherboard btw.

agree with Smicha =) all he way, & here's the link for free standing 9x 120 or 9 x 140 MoRa rads:

here are some photos, I've shared on the other thread =) http://render.otoy.com/forum/viewtopic. ... 1&p=208691

p.s. 240+360 might be enough to cool down three cards, but temps will not be ~40C, more or less 60+C (depending on how fast Your cards will be clocked) Free standing rad might be better solution (at least I'd choose that route, simply 'cos You have more expandability & could reuse later =)

Yeah I'll start a new topic, sorry for the hijack rappet!

I can't take the credit for the component selection, ASyme1 helped me with the build options
