This laptop has fan control feature using the lenovo driver (Energy Management)
Hovewer SpeedFan failed to work correct with this laptop in windows 10, so here is a small utility build from reverse-engineering of the driver
- lenovo driver (Energy Management)
- Binary from release
- Additional: Disable autostart for Energy Management if you don't need it
This software is provided as is, use at you own risk, no warranty provided.
- FanControl.exe fast for fast Fan mode (in my case it consists of 12 high speed 10 seconds intervals with 2 seconds cooldown)
- FanControl.exe normal for normal operation mode
- FanControl.exe read returns driver value for CleanDustState
- FanControl.exe keepfast <code, default = 3> will resend request for the max Fan speed each time the return code differs from the specified
- Execution without arguments, double click will create Tray icon for the application and keep requesting max Fan speed. Right click icon to exit and return back to normal mode
