Single GPU and Single CPU in a Parallel Flow Loop?

[Avathar77]

I have posted this in another forum as well, but would like get some more input.

I have only seen parallel flow loops in multi-GPU configs, but can this be done in a single CPU and GPU setup?


This is the idea



According to what I have read, some say the restriction in GPU bock is lower than CPU block and this will cause majority of the coolant to go through the GPU block while starving the CPU block!

Also, serial is the easiest way to go, I know that, but I think the above way will give the neatest tube routing.

Any thought on this?

P.S


This is how my loop is right now, so tubing is minimal
I don't like the tube from CPU-out to RES-in, that is why I wanted to go for an alternative loop.

Umm, again. The GPU loop will pull too much flow from the CPU block. The CPU needs high flow/pressure to cause turbulence inside the block. You drop below 1 GPM your temps will climb. Just stay series. Or try it and report back that it doesn't work.

You can generally drop well below 1GPM before temperatures climb w/ modern hardware. Flow rate is hugely overrated. I say do it. Try to have similar pressure drop over both blocks if you can. I know the newer EK GPU blocks are very comparable in pressure drop as their CPU blocks.

I have Koolance CPU 370 and Koolance FC 6970 as CPU and GPU blocks.
I know the CPU block has more restricton than GPU block(from reviews).

How to have a "similar pressure drop over both blocks"?

You won't, you should not have your GPU in parallel with your CPU. You will starve your CPU block of water.

I say try it out and see how it does. It shouldn't be hard to revert your loop back if it doesn't perform well.

Yeah I am waiting for my D5 and some tubing to arrive tomorrow, so I will give it a go and see how the temps are. Now I wish I have ordered some clear tubing for this testing

You can't see the water moving anyway when you have your system fully bled.

[Avathar77]

True, but I could see the bubbles moving while bleeding.
