Piyush Puranik, as per http://www.service.asus.com/#!downloads/c1wax an
update is available for your BIOS (214). If you update to this, does it
change anything?
If not, could you please both specify what happened, and provide the output of
the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Thank you for your understanding.
** Description changed:
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 Ubuntu.
+ WORKAROUND: Switching to the Nvidia proprietary drivers seems to have
+ drastically reduced the fan throttling.
