Funky External Setup Question

I_Forge_KC · April 11, 2018

So, I've just purchased a workstation for my business needs, but I want to take it up a notch for some of the work I do.

Current setup:

Dell Precision T7910 Tower

2X Intel Xeon E5-2696 v4 (44core / 88thread)

128GB RAM

Quadro P5000

Dell PCIe NVMe Card (1TB, 4x Samsung 9650PROs (256GB))

Asus AC-88 Wifi Card

I love the system, but I'm already pushing the P5000 to its limits (for GPU processing). After a lot of looking around, I think what I want to do is:

Add an additional P5000 (non-SLI)
Add a Tesla K80

Here is the hitch... the K80 was designed to go into a server environment with high air-flow in the case. This means that the card has no active cooling on it. I'm going to have to water cool it with the water block from BitsPower. I know I could probably just load up on P6000s but the cost difference is HUGE. I may end up ditching the P5000 and do two Teslas, but that's a different discussion.

Here is my conundrum for this: The Dell case was not designed (in any capacity) to support a radiator. I've got the front HDD bays loaded up, so I'm not inclined to swap to a new case (plus, I'm not sure this mobo can go anywhere else). In an effort to cool this thing, I'm looking a the Alphacool Eiswand 360 with a PCI slot bung to route the tubing effectively.

Is it feasible to use a single Eiswand 360 to cool all three (technically four) GPUs? I wouldn't dare add the two Xeons (not that they matter since I can't OC them anyway). I can't find good information on flow characteristics on the Eiswand to be able to chuck into the various calculators. It would be ridiculous to put two on top of my tower, but I'm not opposed...

Any insights out there in LinusLand?

Oh, to satisfy the nosey people, I am a generative design consultant who specializes in topology optimization, lattice structures, and topology synthesis (bleeding edge CAD shenanigans). I write a lot of my own software for this stuff and use GPUs for my number crunching. I know I can rent a GPU server loaded with CUDAs but where's the fun in that? As it is, a lot of the software I use lives on somebody else's server somewhere - with my own software I want to keep it locked up.

Thanks in advance!

A single 360 radiator isn't that much of cooling capacity. If you want to go crazy... consider a Watercool MO-RA3 420 that can host a reservoir + pump as well. You can put nearly any load on a MO-RA and not reach it's limit.
