Fan Speed High

I have often found that the fan speed is high after I install a new version of Ubuntu, so this is what you do to fix it.
This is a slight update to a post I found at: http://askubuntu.com/questions/376636/notebook-fan-constantly-running-at-a-high-speed

1. Install lm-sensors: sudo apt-get install lm-sensors

2. Run sensors-detect which will install the 'coretemp' module

3. Run in terminal: less /etc/modules

4. Modify /etc/default/grub: sudo nano /etc/default/grub.conf

Change from:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

1. Update grub: sudo update-grub

2. Reboot your machine

3. Run sensors on the command line at anytime to see the current temperatures. sudo not needed.
