Bug#727629: general: CPU fan always on (high speed)

Package: general
Severity: important

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
        It's a fresh install (Wheezy and Jessie). There was no changes on the
system, and the fan works on high speed, with a normal temperature (39 ~ 41 C)
on both cores.

   * What exactly did you do (or not do) that was effective (or
        I've tried to reinstall Wheezy several times, upgraded its kernel to
3.9, 3.10 and 3.11.6 versions with no effect.
        I've tried to install Debian Testing (Jessie), that was ineffective
        Killed a lot of applications - no effect.
        Stopped GDM and worked on shell only - no effect.
        Updated BIOS - no effect.

   * What was the outcome of this action?
        No changes. The fan is still working on high speed with no need to.

   * What outcome did you expect instead?
        The fan working normal.
