I confirm the same bug on E555.

Fan speed is always reported as zero. Writing fan speed (with acpi on) is not
effective, as the fan remains at minimum speed no matter the settings. This
lead to CPU overheating and throttling.

At power up, fan runs at full speed briefly; as soon as kernel is loaded, the
fan slows down to minimum speed and does not change speed any more.

With acpi=off, the fan is effective.
