Keeping GPU's separate in a Water Cooling Loop

[Carbongrip]

I have a question, how would I link 2 GPU's that I want to keep separate to a single reservoir, pump, and radiator? Reason is I want to use Quick Disconnect Connectors on both.

Somewhat confused  if you're connecting them to a single reservoir and pump, by definition they will not be seperate.

A reservoir has a single input and output, so how exactly do you plan on connecting 4 tubes to that? You'd need 1 reservoir for each GPU.

Couldn't I use T's Splitters that connect to a single input and output pipe?

That'd also slow down the flow considerably, which might lead to higher temps.

Would it matter if I used a high flow rate pump like this dual pump from EK?

 

EK-XTOP Revo Dual D5 PWM Serial

Maximum flow: 1500L/h

Not pump related. You're stuffing two streams through one input. Just add another rad or do the normal thing and connect the GPUs together.

Are you doing this for a test or something? Doesn’t even seem worth it or being conducted properly.

I would just run those cards in parallel with a good pump like a D5. You're making it to complicated without any notable drop in temperature or gain in perfomance.

Just plug the GPUs with the QDCs in line... no need for "2 loops".

[Marshnt]

Simple make the input different form the outlet so one male the other female.

[Gunndykol]

If you want to be able to QDC and remove one or the other GPU at any time, the only solution is to use 3 QDC connectors.  One before the first GPU, one between the GPUs, and one after the 2nd GPU.  Then you can remove either GPU individually from the system without draining anything if that is what you are going for.

Use T lines.

Its no different than running 2 GPU's in parallel.

So if  you were to use t splitters and run each card separately then you would have about the same performance difference (none) as if you had put them in parallel. I don't really see any issues except that the top card may need the tubes coming off of the top and it may not look as good. Unless you're doing a lot of changing of hardware though I would also recommend putting them either in parallel or serial and then use a qd fitting on the intake and outtake of the series of them so you could still take both out without too much difficulty.
