Acpi/ventilateur

Bonjour,

je suis sous ubuntu hardy. J'ai un probleme avec mes ventilateurs, qui tournent trop souvent (en faisant du bruit ce qui est desagreable).
La machine n'a pas l'air particulierement chaude, et elle est neuve, donc ce n'est pas un probleme de salete.

J'ai cherche une solution sur internet, mais les postes que je trouve font principalement reference a cette methode:

http://doc.ubuntu-fr.org//lm-sensors?redirect=1

Or sensors-detect ne detecte aucun sensor:, et en particulier, pwmconfig ne marche pas.

Y'a-t-il un moyen pour regler ce probleme?

Voici quelques info:

Au demarage du noyau, il y a un bug bios qui s'affiche:

[ 26.432787] PCI: BIOS BUG #81[49435000] found

Voici les references de mon BIOS:
