Fan control sometimes are side effect of AML methods. If you do want to understand how fan control is implemented in AML methods, probably, you need to hack DSDT. If no explict Fan control, at least we need to make sure implicit fan control works But, it depends on platform vendor to implement Fan control in ACPI or not.
