I was able to alleviate the problem with premature shutdown using this parameter, but now I encounter the behavior that I saw described in some documentation: When a certain temperature is hit (I think it is ~84°C), the fan switches to its maximum state, consequently, the temperature drops rapidly (~5-7°C) and the fan's speed decreases immediately, causing the temperature to rise again above that threshold etc. This cycle repeats again and again in ~2-5 s intervals. I also read in some documentation (of the thermal module IIRC) that there is some mechanism to avoid just that unwanted behavior by some hysteresis parameter which should provide that the fan does not switch off until the processor is cooled down more thoroughly. However, I could not find any way how to do that on my system (intel HM65 chipset), as the virtual device does not seem to offer setting such a parameter. I could also not find a cooling device of type 'fan' in my /sys directory, only four virtual cooling devices of type 'processor' and one of type 'LCD' (so I do not quite understand how the system even controls the different fan levels). Can someone give me a hint (or reference to some documentation/how-to) on how to achieve a sane cooling strategy for my laptop? Is it possible anyway?
