I am building a professional workstation based on Threadripper Pro to support up to 4x GPUs (see previous thread: Designing a four-GPU Threadripper Pro System)
I am looking to support GPUs that are typically only passively cooled (like an A100) and therefore need a watercooling solution. As this is a professional workstation, I will be swapping GPUs often and therefore am using EK’s Quick Disconnect manifold system. I am using two radiators: 1x 480mm EK-Coolstream XE and 1x 360mm EK-Coolstream XE. I am (attempting) to fit all of this in a Fractal Meshify 2 XL.
As this is my first watercooling loop build, I reached out to EK for design help and this is the schematic for the design they suggested. They recommended using two pumps in parallel to provide increased flow rate as this loop will have a lot of flow restriction.
To be honest, I don’t fully understand the choice between series/parallel and pressure/flow rate, but I figured the folks at EK should know what they’re talking about and just went with it.
(disregard the fact that the schematic shows two 360mm rads)
The problem is that I’m having the damnedest time figuring out how to actually fit all of this in the chassis.
I’ve experimented with many different arrangements. Here’s my current prospective layout, but it’s already very tight, let alone once all the fittings and flexible tubing are in place. It certainly doesn’t help that these radiators are crazy thick.
The other problem with this layout is it requires using the back plate to mount the reservoir. This is a problem because the E-ATX board blocks the typical routing holes for the 24pin mobo power connector, forcing you to come from the top which makes the provided cable too short and otherwise just being in the way of the RAM slots. If I could remove the backplate, I could route the cables around the side of the mobo as usual.
Overall, I’m looking for feedback from folks on the loop design. How would you design a loop for a system like this?
I am also looking for ideas on how to actually fit and layout the loop in the Meshify 2 XL. Or maybe I should just upgrade the case to a monster like the Corsair Obsidian 1000D?
