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.

  1. Install lm-sensors: sudo apt-get install lm-sensors
  2. Run sensors-detect which will install the 'coretemp' module:
  3. Run in terminal: more /etc/modules
  4. Modify /etc/default/grub: sudo gedit /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
