The installed packages from our repository – like Lightcommander, fancontrol-conf, etc. remain installed.

You have to decide on a case-by-case basis whether you want to overwrite the configuration file or not. If you overwrite the configuration files, a backup copy of the old configuration file will be created in the same directory.

sudo apt-get update

Restart your computer now. After the restart please check in a terminal if the fan control is working properly:


The number of revolutions of the fan should now be between 550-650rpm. And the temperatures should be displayed for all CPU cores.
