If your notebook’s fan is always on for some unknown reason, its fan settings might be changed to always on.

You can change it back in the BIOS or using the tool: NoteBook FanControl. If you can’t find your notebook in Selected config, just cahnge it to some other notebooks and try it until it works. If it still doesn’t work, it might not be the software’s problem.

You can check the BIOS settings or clean your notebook’s fan and make sure it isn’t filled with dust.
