Thanks for your persistency! I did some testing and found that even
under Linux the fan stops below certain temperatures (see [1]). But
I can only achieve that low temperatures with an external fan! And
under Vista the fan stops at higher temperatures and sometimes runs
at comparatively low temperatures ([2]--[7])---due to hysteresis?!.
Actually Linux' power consumption and hysteresis seem to keep the
fan running even following powertops suggestions, lowest backlight
brightness and disabled WLAN, Bluetooth and WWAN. :-(

Thanks.
