switch power mode (quiet, balanced, performance) with software.save and load presets for different modes.set acceleration and deceleration for each the fan when the fan speed should increase or decrease.set minimum temperature for each level that must be fallen below before slowing down the fans again.you can use CPU, GPU and IC temperature to control the fan all at the same it.set temperature points when the fan speed (level) should change.set a fully featured custom fan curve with up to 10 points.also fully controllable by scripts or from terminal.small GUI for fan curve other features by GUI tools of distribution.light on RAM and CPU and without telemetry. This has been achieved through reverse engineering and disassembling the ACPI firmware, as well as the firmware and memory of the embedded controller (EC). It allows you to control features like the fan curve, power mode, power limits, rapid charging, and more. Is the alternative to Lenovo Vantage or Legion Zone (both Windows only).

What are the new fan speed sensors? What temperatures are used for controlling the fan speed? My CPU and GPU temperatures are low but the fan is still running? Is the fan speed controlled by power consumption? My fans do not spin up, never stop, or never change speed (after using other tools)? The fans of the Legion Laptop are loud when idle? The fans turn on when doing light work like browsing? The reported temperatures do not change or seem wrong? Even under high load the fans are going not fast enough? After a BIOS update something, e.g. If you have a light in the lid (Y-logo) or at the IO-ports (all Legion 7), please help testing controlling it here.
