Hi Vitor,

FAN speed is usually controlled by the EC / SuperIO. There is no
generally available unified interface for that like Dell's SMM
interface. You might want to look at the ACPI interface to get something
more unified. Controlling hardware directly will be a lot of work for
all the devices out there.
