Don't be _so_ lazy, your display adapter is even mentioned in the context help for RT's fan controls. All you have to do is to read it:
Fan speed adjustment sliders
These sliders allow you to adjust fan speed for the corresponding performance level.
• This value is trustworthy only when the fan is physically connected to the PCB’s integrated PWM
(Pulse Width Modulation) controller. If external PWM controller is used (e.g. F75373S/F75375S
on ASUS V9999 series, ADT7473 on GeForce 7800GTX series) or the fan is not connected to any
PWM controller at all (e.g. MSI NX6800 series), then the driver will not be able to control fan speed,
as well as will not be able to report trustworthy values.
