On Ubuntu > 10.04 or from kernel 2.6.32 onwards: To make the kernel module settings permanent and to make them be executed at boot run below command and reboot afterwards: In Linux 2.6.22 and higher you need to additionally pass fan_control=1 to the module thinkpad_acpi (e.g., # modprobe thinkpad-acpi experimental=1 fan_control=1) It requires the ibm-acpi module to be loaded with the experimental=1 module parameter (e.g., # modprobe ibm_acpi experimental=1). This script works with any recent Linux kernel (2.6.14 and higher). Note that the fan levels, thresholds and anti-pulsing hacks are system-specific, so you may need to adjust them.Ĭomprehensive bash script with fine control over fan speed In addition, they include a hack for preventing the annoying fan pulsing that occurs on some systems. The following scripts sets the fan speed according to the system's thermal sensors. The firmware doesn't update the sensors more than once every 2s, so care should be taken not to waste resources by reading them too often. This feature is only available on 20 models.Closed-loop fan control requires a thermal sensor sweep, which is an expensive operation. Accepted values are 2-7, where 2 is the fastest and 7 is the slowest. Values represent a few seconds each, where 0 is the fastest and 9 is the slowest.ĭetermines how quickly the fans accelerate or decelerate when it is time to change fan speeds. Only available in Discrete Graphics Mode (Hybrid Off).ĭetermines how often LegionFanControl should check the current temperature before deciding to change fan speed or not. Removes laptop control of the fans so they run at their factory maximum speeds. Some users may want to disable this behaviour if they use other tools to manage their Windows Power Plan switching events Will also switch corresponding Windows Power Plans if they existĬhoose whether switching the Legion Power Mode will also switch the corresponding Windows Power Plans if it exists. Stock Fan Curve settings are restored on exiting the application.The maximum allowed Fan Speed in the curve is dynamically determined based on Lenovo recommendations for your model.Decide what the fan speeds should be at each temperature point.Decide the temperature points when the fan speeds will change.Create a custom fan curve for each Power Mode.
