I have a Quad core Q9550 processor, and it is displaying the temperature of 86 - 100 °C. I'm pretty sure that's not correct, since just a few minutes ago I have reapplied the thermal parse and right after that BIOS was showing 83°C. And a few other windows tools have shown up to 100+ C.
The CPU is not overclocked, BIOS settings are default, and the cooler is default too. Windows runs fine at first, but after 4-5 hours it gets terribly slow - I suppose throttling gets enabled? If so, how can I disable it? I guess, this is a motherboard's (Asus P5Q-E) fault, so I'd have to replace it as an ultimate fix?
Update: I've changed the cooler to another one and now it works like a charm. The previous one has been installed badly for 2.5 years (I am one stupid guy).
