Bug Description
The fan on my thinkpad acpi begins in 'level 1' mode on boot or shortly after.
root@portland:
status: enabled
speed: 1875
level: 1
commands: level <level> (<level> is 0-7, auto, disengaged, full-speed)
commands: enable, disable
commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))
After some usage it climbs to
root@portland:
status: enabled
speed: 3387
level: auto
However it fails to drop back to its normal speed once the temperature has dropped back to it's pre-boot temperature.
root@portland:
Battery 0: Discharging, 58%, 04:16:44 remaining
Battery 0: design capacity 84240 mAh, last full capacity 84390 mAh = 100%
AC Adapter 0: off-line
Thermal 0: ok, 33.0 degrees C
Thermal 1: ok, 36.0 degrees C
Cooling 0: LCD 9 of 15
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10
Although the fan is reasonably quiet I assume it would use more battery to spin the fan at the higher speed.

The thinkpad is also pretty thin and doesn't feel at all hot anywhere on any surface.

This was done with the latest mainline kernel, since you always ask for this to be tested anyway. The previous kernels also have this behaviour.
