find out what they have the fan speed locked to...i just put together a new system with an 8800 gt and found bfg had locked the fan speed to 29% which is why my card was running around 75 to 80 deg c under full load.
used rivatuner to make fan speed profiles now under full load it never goes over 61 deg c.
