I installed RivaTuner which has a default of 53% for 2D and both 3D modes. However, it seems that the fan speed never changes no matter how hot the card gets, and instead I'm supposed to use RivaTuner to create my own profiles with fan speeds corresponding to temps.
Are the fans supposed to adjust to temps accordingly, and if so, do I need to change anything in RivaTuner to allow this to happen? I ask because my temps under load are around 70 C and I'm trying to bring it down.
Reference design 6800 cards are not supposed to change fan speed according to GPU temperature. These cards have independent 2D/3D fan speeds, and both of them are set to 53% duty cycle by default in reference 6800 BIOS images. So your situation is pretty normal.
