I had been running Windows Xp as my operating system. I would like to know that is there any GPU fan control software which can make the fan run at 100%. Basically all works fine ok, but have noticed that the gpu fan seems to run constant at 100% speed which is quite loud as it sits on our shared desk. My computer is self built and comprises an Asus P5N32 SLI SE Deluxe motherboard, Intel core 2 duo E6400 CPU, 2 x Gainward Bliss GeForce 6800 GS "GLH" Golden Sample GPUs, 2GB Crucial Ballistix RAM and Akasa 650W psu. Is there any GPU fan control software? Any one has any idea about it? Any help you can provide would be greatly appreciated. Thanks in advance.
