fan & thermal

Hi,

Please excuse me if this question has already been raised but I couldn't find an answer in the archive.

I have a compaq laptop with ACPI running Debian with acpid and acpi installed. My problem is that the fan is always on (whereas it is mostly silent when running on windows).

I looked in the doc and I don't understand why I am on active cooling whereas the temperature is below the trip point:

$ cat trip_points
critical (S5):           96 C
passive:                 90 C: tc1=4 tc2=3 tsp=40 devices=0xcbf6e6e8
$ cat temperature
temperature:             49 C

Note that I do not have an "active" trip point defined. Also note that /proc/acpi/fan is empty.

Thanks in advance for your help,
Nico.
