meantime, I've especially observed this situation that after some higher load, the CPU stays at pretty high temps, even though what produced the load has stopped and top show basically nothing, just now it's e.g. on: $ sensors coretemp-isa-0000 Adapter: ISA adapter Package id 0: +77.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +76.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +73.0°C (high =

reason, but right now it already runs hot for several minutes. I'll try the older 5.2 now (with the current microcode) see whether that changes anything. Cheers, Chris.
