It turns out that my CPU block wasn't installed properly. I took it out and saw that the TIM wasn't covering the cooler's entire square shape on the IHS. Anyway, after re-applying thermal paste (MX-4) and reseating the block, I'm getting around 81c under full load, steady! Definitely an improvement from temps getting to 90c. I think the problem was that I wasn't applying the correct pressure when turning the screws. I never know how much it should be, and also there's the fear factor of applying pressure on such an expensive CPU... :biggrin: Thank you for your help!

@c-attack, thanks a lot for the detailed explanation, I've learnt a lot. Do you think it's also worth a shot to reseat the cooler to make sure there's no bad contact between it and the IHS as LeDoyen suggested above?

Coolant temperature is around 34c when idle, and steady at around 39c running on full load for several hours. Looks like it never passes that 39c mark. The curve I built has the pump and fans spinning at max RPM at that point. I haven't tested with Prime95. I'm running multiple video encoding jobs in parallel which saturate all the cores to 100%. Is 39c considered high for the coolant temperature?

I'm getting very high load temps from 3970x with H150i Pro XT (push). No overclocking and I've disabled PBO in the bios. I'm measuring with AMD Ryzen Master and getting 45-50 when idle and 85-90 on full load. Is this normal?
