Thanks for support people

but:
As I said, fan works great, i don't even need a heater to be on, fan blows out the heat, but it cannot do as fast, as the processor warms up. There's no dust, i cleaned all vents.
Of course in BIOS setup there is no option that could control anything related to processor speed and/or temperature.
If there is enough thermal paste to run Vista, it has to handle BT, so i don't think it's a hw issue. I don't want to open the laptop because of the warranty.
I still bet it's the driver's fault (erm.. missing driver's fault?). Is it possible at all to put it to the disc? (to do it so, that it's gonna work

)
