Legion Fan Control v2 released


Recommended Posts

The app created by a group of enterprising coders has been revamped to provide even more functionality. Here's the full feature set:


  • Full real custom Fan Curves!
    • Create a custom fan curve for each Power Mode
    • Decide the temperature points when the fan speeds will change
    • Decide what the fan speeds should be at each temperature point
    • The maximum allowed Fan Speed in the curve is dynamically determined based on Lenovo recommendations for your model
    • Stock Fan Curve settings are restored on exiting the application
  • Switch Legion Power Modes
    Will also switch corresponding Windows Power Plans if they exist
  • Windows Power Plan Control
    Choose whether switching the Legion Power Mode will also switch the corresponding Windows Power Plans if it exists. Some users may want to disable this behaviour if they use other tools to manage their Windows Power Plan switching events
  • Turbo Mode
    Removes laptop control of the fans so they run at their factory maximum speeds. Only available in Discrete Graphics Mode (Hybrid Off).
  • Hysteresis
    Determines how often LegionFanControl should check the current temperature before deciding to change fan speed or not
  • Read the current Fan Speed
    Now in RPM values
  • Fan acceleration speed

    Settings are auto-loaded at launch
  • Launch at Start-up
