OK, well I'm not sure about the acpi module, but I know my fan is running alot, never seems to shut down anymore. maybe it's just dirty. but thanks!

What were those commands you typed in to make the fan stop?

Assuming the thinkpad_acpi module is loaded with experimental=1 and fan_control=1, the following will work:

echo 0x2F 0x00 > /proc/acpi/ibm/ecdump (fan off)

echo 0x2F 0x02 > /proc/acpi/ibm/ecdump (low speed)

echo 0x2F 0x04 > /proc/acpi/ibm/ecdump (medium speed)

echo 0x2F 0x07 > /proc/acpi/ibm/ecdump (maximum speed)

echo 0x2F 0x80 > /proc/acpi/ibm/ecdump (automatic - default)

echo 0x2F 0x40 > /proc/acpi/ibm/ecdump (disengaged)

Be careful about shutting off the fan, for obvious reasons :)
