Yes. But under Linux the fan is running at temperatures at which
(right grammar?) the fan is not running under Vista. I would
understand if the fan was running more often and even faster under
Linux. But it's constantly running---at comparatively low temperatures.

What about my question on thinkpad_ec? Might it effect fan's
behaviour? It fails to load on my X200s. Yesterday I tried to
install a vanilla kernel (to be able to possibly file a bug in the
Kernel Bug Tracker) but compilation failed for reasons I do not
understand yet.

Best
