Program for Linux-based OS to control Fan Speed on Lenovo Yoga 13.
Inside the Lenovo Yoga is an embedded controller (EC), which is responsible for some of the Yoga's low-level tasks. One of them is Fan controling.
There is 'notebook fan control' programm for controlling Fan on windows in internet.
Temperature Monitoring and Fan Control
There is a CPU temperature sensor connected to the EC via SMBus; note that this SMBus is not accessible by the CPU, and so the Linux i2c drivers cannot see any devices on this bus.
The fan is connected to a fan controller in the EC, which allows the fan speed to be varied (using PWM) between 0% and 100% duty cycle. By default, the EC sets the fan speed very strange. All time works on 60% of maximum fan speed.
This program works in automatic mode. It's controling Fan with my custom temp table. You should run it as root in background. I plane to make linux kernel with this functioanlity.
You can compile program from source.
Compiling from sourse:
sudo apt-get install gcc-4.9-base cmake git g++ git clone https://github.com/blan4/lenovo-yoga-fan-control.git cd lenovo-yoga-fan-control cmake CMakeLists.txt make sudo ./yoga_fan
For running script at runtime do this as ROOT:
sudo -s make install update-rc.d yoga_fan_daemon defaults
If you use system.d you should copy service file yoga_fan.service to /etc/systemd/system/ directory. After that enable service by
sudo systemctl enable yoga_fan.service
- add daemon for ubuntu
- add daemon for systemd based
- add config file
- widget with fan speed and temperature
- add fan device output and input to /sys/class/hwmon
