With AC MX-4 thermal compound, the temperature stays @ 2.4GHz in idle at ~ 32 ° ... and under full load ~ 43 °.
The installation was indeed relatively straightforward, but one needs to have a quiet and strong hands, as the cooler quite slips when pushing down the lever for securing on the AMD retention module.
I had the first installation no WLP plan, which meant that the CPU very quickly overheated & abschaltete.
This is probably due to the uneven surface of the cooling block, which does not "plan" is so polished.
