(first loop) cpu temperature - is it normal?

[happf12]

Hi. I finally came around to building a loop to cool a 5960x. The relevant pieces of the loop:

EK Supremacy Evo Waterblock, 2xEK DCPs 4.0 (extra umph for adding gpus later + rads are external) and 2 x 540 alphacool 45mm rads (3x180mm, silverstone fans) + MX2 thermal paste.

With an ambient temperature of 20-22C, and with the cpu on stock settings(for now), my

-idle temps are close to ambient (hottest core 24C) 

but

-while normal stressing (e.g. gaming) they spike up to 32-33

and while stressing with AVX instructions (say prime95) they peak at 40-43C.

 

Temps by realtemp/aida64. Readings from Afterburner are for some reason much lower.

 

So are these temps normal for this kind of raddage? Shouldn't the twin 540s be able to keep the cpu @ ambient? They have more rad space than a 1260 Mo-Ra3! It's my first loop, so I didn't know what kind of temps to expect. Just want to make sure I didn't mess something up

The temperatures are completely normal.

Yeah I'd say so. Although you have rads up the arse, there comes a point when the extra surface area doesn't have much extra effectiveness cooling wise. However, when you add some video cards to the loop I think you'll notice the extra rad space kick in a little more.

That's pretty much what I'm getting, and I'm running two 480 x 60 alphacool rads (with two 780ti's in the loop). My GPU's never get above 40°C. I think you have plenty of rad.
