Max Operating Temperature (Blender)
To check the operating temperatures, I run Blender instead of Prime95 and small FFTs, which apply an unrealistically high load to the CPU.
The max operating temperature in Blender is low at 77C. Even at the extreme performance profile, the maximum temperature stays controlled using a top-performance air cooler (Noctua NH-D15 G2). Strangely enough, the 13900K also achieves a low max temperature here despite its high power consumption. If I kept the load for a more extended period, 15-20 minutes, the 13900K’s temperatures would climb higher. For reference, in Prime95, the 285K has a 5C lower max temperature than the 13900K.

Given that you are mostly known for the PSU Wizzard, you should also include the whole system power draw (idle most importantly) with or without dedicated GPU. This is important when choosing PSU based on the given power draw (choosing between PSUs with low load performer or normal load performer).
Whole system power consumption is affected by the PSU and the rest parts I use. Most of you won’t use the same so I believe that providing exclusive CPU power figures is the best.
The U9 285K has no AVX512 only AVX2 or am i missing something?
yeah my mistake there, was left from the template review I used 🙁
yeap.
