Basically, I just installed a new motherboard to add a 2nd 8800gt. SLI is working, but the cards are too hot. I solved part of the problem with ntune by turning up the fan speed. One of the cards now idles in the 50s. But I can't get the 2nd cards fan adjusted. I can adjust the same gpu by using rivatuner, but not the way the rivatuner guide suggests. Anyhow, when I hit the "fan" tab and select "direct control" in the dropdown, the only slider that lights up is the third "3d" but it won't move at all. Why isn't this working? I just want to be able to turn up the fan on the 2nd gpu like I can the first. If someone can give me a quick fix for this so I can play right now without overheating, I'd really appreciate it. System is: e6750 clocked to 3.2 4gb mushkin redline at 1000 750i ftw 8800gt X 2 coolermaster 600w vista 64
Settings are applied to both cards when SLI is active. You cannot access each card independently. Because it is not supposed to work with such hardware. Separate 2D/3D fan speed control was in use on NV3x/NV4x series only. Modern hardware use temeprature based control instead.
