Basically to cut a long story short HP directed me to using RivaTuner to try and regulate my fan speeds, which are always extremely loud and fast. However, i have studied the guide for regulating and creating fan profiles and when i go to Customise and click the graphics card it doesnt actually give me any options to change the fan speed. I have NVDIAI GEFORCE G0 7400 and was wondering if anyone could shed any light on why i cannot change my fan speeds? Thanks Kiran
