I am interested in writing a software application which allows my GTX 450 to increase, or decrease the speed of the fan based on the current temp Value, so that my card will auto adjust itself to a certain temp at all times without me having to change fan speeds.

However, i do not know how to go about accessing the values on the card that will give me fan speed, temps etc...i know there are programs that do this like EVGA precision and i can change fan speed etc etc...but how would i go about doing that in my own software app?

Thanks for any help!
