From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 1f27dbd8265dbb379926c8f6a4453fe7fe26d7a3 ]

Allow the user to configure the fan to turn on / speed-up at lower
thresholds then before (20 degrees Celcius as minimum instead of 40) and
likewise also allow the user to delay the fan speeding-up till the
temperature hits 90 degrees Celcius (was 70).
