Am I doing it right?

post #1 of 6
Thread Starter 
So I'm building a water cooled pc and I have some specific questions.

loop?
_______-> rad1 ->_______-> CPU ->
pump ->________-> res ->_________-> pump
_______-> rad2 ->_______ -> GPU ->

the splits will have a Y fitting

I'm going to run an SLI config so I'm thinking two 360 radiators on the front of an Ascension or Extended Ascension case with the rads mounted on the front (if that's even possible).

Also, will one D5 pump do the job or do I need two/ split loop etc?

Splitting the loop into parallel branches is usually a bad idea, unless it is splitting for parallel flow through identical water blocks, like for multiple GPUs.
The branch with less restriction will tend to get the most water flow, potentially starving the other branch for cooling.

Thanks for the info. What would be a good alternative to my idea? Should I split it into two separate loops?

Serial loops are by far the easiest and a D5 can take a cpu and 3 gfx blocks np. Just go res > pump > cpu > rad> gpu 1> gpu 2> (gpu 3 if you have tri-sli) > rad > res. You will get better temps than splitting the 2 360s. Order for the most part doesn't matter because tepms equal out over 30min/1hr of running. And actually splitting into 2 loops with 2 360 rads is a waste you would be better going with a 480 for the gfx loop and a 240 for the cpu loop if you go that route. Cpus do not need a 360 rad and a 360 rad for 2/3 gfx cards is cutting it a little closer than I would recommenced. Typically I recommend 1.5 rad spaces per water block. So 2 examples: 1 cpu 1 gpu is good on a 360 rad and 1 cpu 2 gpus is best with 360+240 or 480+120.

This helps a lot. Thank you!
