Watercooling for dual Xeon Workstation

post #1 of 6
Thread Starter 
Hi guys! I'm seeking some advice about watercooling two Xeons I just bought.
1) I have a 360 Nexxxos UT 60 with 3 Gentle Typhoon 1850 in the back of my case and I would like to know, if it will be enough to cool 2 Xeons E5 2689 with 115w TDP each and keeping a Delta of less than 10°?
2) And what if I would include my Firepro v7900 as well? At the moment the Firepro is the hottest component and every 6 - 8 weeks I have to take it out and clean the heatsink. It has almost no dust and looking through the fins, I can't see any dust - but it still helps to get it down from 81° (idle) to about 72°(idle).

The cpus are my priority but if I could solve the problem with the Firepro too, that would be awesome.

Cheers

I recall seeing someone who build a dual xeon watercooled workstation. Pictures here: http://imgur.com/a/FwUnB
He used a 480 for the CPU loop, and the GPUs were air cooled.

What case are you using? If you have more room in the case for a ~240 it wouldn't hurt. I think ~450W of TDP on a 360 might be pushing it if you want to keep fan speed low.

He is even using two psu :O

I have an ancient Thermaltake Armor+ but place shouldn't be a problem. I could install a 240 rad on the bottom or a 140 in the front if necessary. The question is, if I even need that many rads. In another thread here, a guy got the advice to cool his two 2687w, 130w TDP each, with a 280 rad.

Hmmm, I just don't want to buy parts that I end up sending back

Well, if you already have the 360 Nexxxos UT 60, why not build your loop around that to start. It is a 60mm thick rad, so if the temps aren't good enough you can add more fans for a push/pull configuration. The beauty of the custom loop is that should you want to upgrade later, nothing is stopping you from throwing in another radiator of any size that will fit in your case.

Keep in mind the Xeons are locked, so you don't have to worry about temps limiting your overclocks.

The UT60 w/ the GT AP-15s will do fine. I have two 2660s on a 2x140mm radiator w/ the AP-15s @ 5V and the CPUs don't break 40C. A non-overclocked CPU just doesn't throw a lot of heat.

Thanks, that sounds really good! As soon as I get the second cpu block and the cpus and I will see to post my results here.
