Hi I have a laptop (Fujitsu Siemens Amilo 4000), I'd like to control the cooling fan manually.
How do I do that?
/proc/acpi/fan/ is empty, the fan is otherwise working well.
Distro is Fedora 14.

The fujitsu_laptop module dans control acpi for Fujitsu-Siemens laptops does not appear to have fan control code (as of today) see:
(You can look at the thinkpad acpi code in the same directory, it has a fan subdriver)
I don't think it's possible to achieve what you want to do with your hardware.
I would look at the sys devices directory. For example, in Sony Vaio laptops, you can turn on the fan to max speed with this command:
while [ 1 ] ; do echo "255" > /sys/devices/platform/sony-laptop/fanspeed; sleep 0.1; done
In your laptop, try doing a:
find /sys/devices/platform/ -name "*fan*"
or manually inspect the directory using tree, looking for something that refers to fan speed:
tree /sys/devices/platform | less
