[Bug 1160081] [NEW] Cooling fan is always turned off, causing overheating

[Ivan Danov]

Public bug reported:

lm-sensors fails to detect a pwm sensors, when running sensors-detect.
There is no way to turn on the fan and that often causes overheating,
where computationally intensive tasks are to be run.
