Overclocking and controlling fans on GTX 4X0 Cards
I have always used Rivatuner to control my video cards fan speeds and overclocking but since the current version doesn't support it I needed to find another way to do this. I tried EVGA precision but didn't like the way it handled the overclocking. I came up with a way that works using Nvidia System Tools and the Nvidia Control Panel.
After installing Nvidia System Tools I went into the control panel and made a profile under device settings under the performance tab to manually set my fan speeds and core/memory clocks on both cards. I then set up a rule under profile policies to load my custom profile when windows starts. I am monitoring my video card temps using system tools also. Seems to be working really well so far. Hope this is useful for somebody!
