Cooling question

[Toasted Waffles]

So I just finished my build with two 3x120x54mm rads and I’m running a 5950x and a strix 3090. On my cpu I see from mid 30s idle to 40s and running a game I see mid to high 70s on the cpu. My gpu stays in the 60s while gaming. I have a d5 pump in the distro block and I have it set to full speed but it seems to be moving slow. Is this to be expected ?

Sorry D5 pump set to full Speed?!? the D5 is an industrial pump and even with a high resistance loop e.g. 4 gpu blocks it only really needs to be set to about 50% at most. water that seemingly moves slow is normal. I would say your fans and their seal against the radiators is going to have a bigger impact on temps that your pump speed. I bought the Lian-Li SL120s and they do not seal against my rads at all and have virtually no static pressure so my temps are in the high 90s despite running 3 triple rads.

Normally I don’t run the pump that fast but when I first built the system I had issues getting the coolant to move up thru the loop (also made some strange noises, not my first d5 but the first time using a built in one in a distro) I have Corsair ML fans both pulling through the rads

I would say your temps seem fine so there shouldn't be any issues unless your flow indicators are spinning very slowly e.g. 4-5 seconds per rotation everything is probably fine. if you are running any blocks backwards it could explain lower flow rate however.

do you have a pic? i no some distor plates were having problems with some d5 pumps but you think they fixed them by now.

It’s an ek reflection block

I didn’t think about the backwards block. I had to run it backwards on the gpu…. Should I swap the flow on it ?

ur pump spped or flow rate is 99,9% not the problem.

 

try turning the top fans around
