I would try this:
nForce System Tools with ESA Support
I believe your board supports ESA. I use it with an XFX 780i and it does everything. BIOS changes, temp and voltage monitoring of the mobo, graphics and CPU. YOu can alter fan speeds of the CPU and graphics cards. Mobo fans too if they are connected to the fan headers. It will also allow you to view and alter your BIOS from windows. Updates the BIOS as well. It works perfectly.
