High temps custom loop

[Kcm1318]

Excuse me if this has been posted over and over but I think some of these are case by case. My pc is running 9700k and 2070 super I put together a loop with Corsair xd3 pump/res, Corsair cpu block, two Corsair 280mm rads, 4 af140mm fans And a Evga copper water block. My temps are high i think, with both cpu/gpu idiling around 40c and Both maxing out at around 75c I reseated both cpu/gpu, and bled system of air. I am curious if my fans which I did not realize are not optimized for static pressure are creating such an issue. This is my first custom loop, any help is appreciated.

are the cooling plates having a good contact?

is that with full blast on fans and pump? 

 

how large is the room you have the pc in, what is ambient room temp?

Yes they do have good contact.

yes it is full blast on pump n fans. Fans don’t get over 1200rpm and are not optimized for static pressure could that be the issue? Room is 20ft x 20ft ambient temp is 24c

hmm, my fans are 2.2k max and fans usually run around 1k, quiet noisless. and pump at 30%.. i have the EK-Vardar X3M 120ER fans(high static preasure) . after leaving system on, on a warm summer day,  temps are idling between 33 and 45 on the cpu and watertemp at 35C.. in a 2x3m room. it cools down more if i open the window

 

altho i have a 9900k and two rtx2080ti's watercooled.  6 120 fans and 1 140 and radiators on all of them.

Static pressure is certainly going to play a part but touch your rads when the component temps reach 70C.

 

If it burns the **** out of your finger(as 70c would) then you need to get rid of more heat with better fans.

If the res metal body is just slightly warm then your gpu/cpu block is not efficient at getting the heat out of the components.

Maybe better thermal paste or something is causing it to not seat properly.

 

I'm in a fairly similar situation that I repurposed an old Intel CPU block for my new Ryzen cpu. The cpu temps can change rapidly because I think intel cpus are slightly rounded and AMD ones are slightly hollow. So block just doesn't make great contact, it works but still gets up to 70C under heavy loads.

The water should never get more than 40-50 before the fans starts pushing air, it should cool it down then.. if the water already is getting warm  CPU at 75 is not bad realy.. it's when it hits 90+ you will see thermal throtteling, the gpu should be good for 84C too .. just see that your water heats up when it gets high and your fans start pushing air to cool the water down.
