@danayer Hmm. Writing works but the value is overwritten a few milliseconds later again. Please try my new version again, run ./setmyfancurve.sh instead and provide the same outputs again.

There might be a way to prevent the the firmware in the embedded controller from overwriting it again with the default values. I might be disassemble it the the future but not now. So I guess setting the fan curve will not be implemented now.

Is there any other features needed by you?

There are some additional features implemented that are not in the GUI yet. They are in folder /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/

ls /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00

firmware_node             issupportgpuoc        powermode

You can read and write to most of these files to read and set properties, e.g.

# read rapidcharge status
cat /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/rapidcharge
# enable rapidcharge status (as root)
echo 1 > /sys/module/legion_laptop/drivers/platform\:legion/PNP0C09\:00/rapidcharge

If it returns an error, then it is not available for your model. Otherwise, you can test if it has an effect. You can check all these features if they might work for you model.
