Hi Jarmo2127,

Does your system have the standard heatsink or the liquid cooler version?

It sounds unusual for the heatsink to fail as I would expect it to be accompanied with a BIOS error at boot, i.e. fan or pump not running. It could simply be a case that your heatsink paste has dried out and not performing as it should. I would buy some good quality CPU thermal paste, remove your HP heatsink, carefully clean the old paste from the heatsink and CPU, (use alcohol), then re-apply some fresh thermal paste before re-installing the heatsink.

I would recommend some Thermal Grizzly Kryonaut compound. This is one of the best CPU thermal pastes available in terms of heat transfer/performance.

Its also worth while to give the inside a good clean if its quite dusty inside.
