I just added a second card and noticed it was 10c higher than the other. I used ntune to monitor the temps on both cards. I disabled the fix fan control that was @ 100% and after a few minutes both cards where same temps. My conclusion is that Riva had only 1 card's fan @ 100% Does anyone know how to enable both cards?

Answer found on a thread:
In the RivaTuner "Main" control panel under "Target Adapter" drop down tab,you have 2 choices... 1st: NVIDA GeForce 8800GTX/Plug and Play Monitor 2nd: Nvidia GeForce 8800GTX/(Default Monitor)
You have to enable both of them....Hurray,let the overclocking begin!
Apperently this currently only works on XP Vista only has 1 setting
