controlfans's Introduction

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.
