In standard bios config, without OC, only with XMP enable my 10900k go to 4900 bost on all cores.
In short test (for example one run of cinebench) it warms up to 70'C - 75'C. It does not start to throttle .
But in longer cycles, + 60sec cinebench, blender test, temperatures go above 80'C for moment and in go down to stable 4400. When on 4400 average temp is around 67'C.
The temperature at rest and lightly loaded is about 35'C.
