The main limitation of such software is that to turn fans off will only work on adjustable fans and most of the fans aren’t adjustable.

You can check the fan software, if any of the above-given works for you then you can download them that let you turn on/off or regulate the speed of the fan and other fan control functions with a huge range of possibilities.
