Graphics card GTX280

[Samra]

hello

I bought computer with a MSI 280 GTX

problem I feel that the fan is not running faster when I run a game that when I am under XP.

in the settings via the nvidia control panel is an option with
parameter fan

direct control of the fan or temperature control

but all is gray and I can not change.

What software or how I can manage it for the fan runs faster when I play.

thank you
