Just a few questions about water-cooling

[Aaron]

Ok, so I have decided to water-cool my duel Xeon build.

I have a few questions regarding what is best. Obviously with the Xeon E5-2600 series processors that I will be using there isn't much over clocking but this being a workstation I will be sitting next to it 8-12 hours a day. Needless to say I want it to be as quiet as possible.

I have set myself a $10,000 (US$) maximum. I know that it may seem like a lot but keep in mind that this workstation is how I make money so the faster it is the more i can make in less time!

My motherboard will be the ASUS Z9PE-D8 WS and my processors will be Intel Xeon E5-2687w (x2) (150 watts each)

As for graphics I've decided on one (possible 2) NVIDIA GTX 690(s) (300 watts each) as the programs that I use love CUDA cores and 690(s) have CUDA cores in spades.

For sure I want to water-cool my Xeons and my GPU(s) so what do you guys think? Will 1 loop work with all of this if I have big enough radiators/pumps? I will be mounting my radiators externally to a wall mount that I am going to fabricate (I have access to CNC mills and a high pressure water-cutter) I am going to use more radiator than necessary so I can run my fans slower. I understand that more radiator area doesn't equal cooler temps after a certain point, I just want this thing to be silent. I'm considering using 3 Black Ice GT Stealth 420's with Noiseblocker BlackSilentPro 140mm PK1 or PK2 fans. Am I crazy? too much? Not enough? I'm new to water-cooling so I really don't know. What about my fan choice? I was thinking of just doing push, but I can do push/pull (since it is mounted externally) if it is worth it.

Will a duel D5 pump (bitspower Duel D5 ModTop) be enough to run something like this?

What about water-cooling RAM? I know that it doesn't get all that hot normally but this is a system that will be run at 100% for hours on end on a fairly regular basis. I'm mostly concerned about stability and longevity of parts. I am going to have 64 GB of RAM at 1600 MHz (Corsair Dominator... The applications that I use don't benefit from ECC Memory all that much)

If you see anything that seems way off please let me know. I am still in the very early stages of planning this build and am more than willing to make changes!

Thanks for reading and thanks in advance for any replies.

firstly there is no need to watercool your ram, if your worried about temps just make sure there is enough airflow in your case and if your still worried buy ram with a large heatsink.

i have never build a watercooled system with so many components in a single loop but i am fairly sure a single loop would suffice if you have an adequate amount of radiators and a strong pump/pumps. a dual loop is also an option here with if you wish the cpu's on one loop and gpu's on another.
as far as i know the 500 series has better cuda performance than the 600 series, so a 590 could be more appropriate here.

Interesting, I'll look into that.

The 600 series do indeed lack compute performance so a 580 would be far better than a 680 for example. The latter would make the better gaming card of course, but if that's not what you need...

Regarding Ram. I never considered cooling my ram, it never gets warm let alone hot. However, after watercooling my GPU's and CPU there was NO air-flow in the case any more - other than over the hard drive - so my ram does actually get quite warm to the touch now. Not hot by any means, but enough that I now have a low-rpm (very quiet) fan above my ram pulling hot air out of the top of the case - and as a result pulling cool air in via the mesh front.

Incidentally I couldn't get a water block for my motherboard (PITA) so the air-flow provided by the fans should prenvent too much heat build up there. Would have preferred to block it of course.

with dual cpu's and gpu's I'd say your probably better off with a dual loop setup. One for cpu's the other for gpu's. With that said what if any water cooling experience do you have?? Its not hard mind you but if this is your first foray into it you have deffo jumped in with both feet. So I advise go slow be deliberate and diligent. Never been a fan of the Black Ice rads just never seen enough good stuff about them, however the Phoyba 420 that I am using is da bomb I love it.

If you have access to a CNC mill have you concidered making your own waterblocks for the MB as this is something ive been looking into a fair bit but untill i get my hands on the board i dont know how practical it will be. im only saying this as top said that the chip-set got warm and running a few high speed cards maxed out might increase the temps abit, let alone what you can do with looks.

Apart from that i completely agree that last gen gtx cards are so much better for compute tasks.
