The ASL show that all temperature related functionality are in the
embedded controller.  This is certainly a micro controller with
his own firmware and will perform all fan related actions (amongst
others things).
There is maybe a bug in the firmware for this IC, since the
temperature was stuck.  You should complaint to ACER
(this is certainly reproducible under Windows).
