ControlFANs

Simple GUI written in QT to configure FAN PWM via HWMON interface. You could use it to setup the kernel auto point for every FAN who support it.

Build

$ git clone https://github.com/amedeos/ControlFANs
$ cd ControlFANs
$ qmake
$ make

Usage

You can start ControFANs with sudo in order to edit hwmon files, otherwise, if you start it as normal user you could only see the fan configuration.
