  CPU fan constantly at high speed on Asus K53SM laptop

Status in “linux” package in Ubuntu:

Bug description:
  I have Ubuntu 12.04.1 LTS installed on my Asus K53SM alongside Windows
  7. Ubuntu has been installed on a seperate partition and I am using
  the GRUB loader for booting.

  The CPU fan on my laptop is constantly at a very high speed
  irrespective of whether I'm running any CPU intensive applications or
  not. The CPU's reported temperature is 42 degrees centigrade (room
  temp is 28 degrees). The air being ejected out of the system is cold
  and not warm enough to warrant a high fan speed.

  I have installed bumblebee to ensure that my Nvidia card is not
  constantly running and I ensured that it is fully updated to the
  latest version. All the reported updates have also been installed on

  WORKAROUND: Switching to the Nvidia proprietary drivers seems to have
  drastically reduced the fan throttling.
