Cuz the one I've been pointed to: http://www.guru3d.com/article/rivatuner-20-fan-speed--overclock-guide/ Does not seem to work? I'm trying to set fan speed by core temp and when I get to the "Core temperature monitoring data source setup" window...I see no "Thresholds Settings" and I am unable to proceed? Not a complaint at all...this is probably the most extensive program of it's type I've ever seen...but...I'm no expert and need to be led by the nose for the 2 things I want to do. Set fan speed by core temp and OC my GTX 260 in 3D high. I'm on hold until I know what I'm doing. ;-)
