i dont know if this belongs here but i have a gainward 7900gt ,, it comes pre OCed so the fan is spinning quiet fast, i have tried using rivatuner and expert tool to slow it down but they dont have any effect,, the temps are ojnly at 50 idle so i know i can lower the 2D fan speed safely enough,,so does anyone know what would get the fan speeds to lower,, any help would be apreciated
