Question

Geforce GPU fan speed control

Asked by: kickstart

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. The OS is Windows XP Pro with service pack 2 and all current updates. My problem is that the GPU cooling fans generally run at about 85% speed with occasional bursts up to 100% if the room is warm. This makes it pretty noisy. The installed software for the GPUs includes the EXPERTool control panel within which there is a provision for manual fan speed control. If I use this to reduce speed to minimum (50%) the fans just speed up again after a few seconds. Does anyone know if there is a software patch or any other workaround I could use to keep the speed down? I believe I have the latest NVIDIA Forceware release 90 drivers installed. The fans don't need to be at high speed as the GPUs run pretty cool, generally around 43 degrees C and most of the time I'm not using the 3D capabilities. Peace reigns (comparitively) with the fans at 50% and I would like to keep it that way unless I'm pushing the GPUs with some heavy 3D action.

I use Rivatuner to modify fan speed and other settings.

Hi Danis
I tried installing Rivatuner but I got the same result with the fans speeding up again after a few seconds.
However I noticed amongst the downloads on the guru3d site was a new beta ForceWare 160.03 which has only been released today! I dowloaded and installed it. This gave me more tuning ability but also removed the gpu fan control from EXPERTool and the Rivatuner fan control was still doing the same thing. BUT the guru3d site also alerted me to the fact that NVIDIA nTune  5.05.38.00 was available and compatible with my mainboard. I can now control each fan separately via the mainboard chipset and the speed stays where I want it. I reckon I have mostly solved this problem myself but you deserve the points for giving me the link to the guru3d site. Many thanks.
Best regards, Nick aka Kickstart.
