Look into /proc/acpi/ibm and do e.g.
	cat fan

You can set the level then (like on. off. auto), like
	echo "level 0" > fan
or
	echo "auto" > fan
or
	echo "level 1" > fan
	(lowest speed)

But be careful. If you manually set the level then the auto function is
disabled, i.e. if you set it to the lowest speed it will stay there
regardless of how hot your CPU gets.

Pitily those AFAIK cannot be controled.
