We've did some power consumption tests between three cards, the 8800GTX, 8800GTS 640MB and the 8800GT 512MB. As expected, the 8800GT consumes the least power, very much due to its smaller die.

The stock cooler of the 8800GT does it work, but not that effective overall. The below temperatures are recorded in an ambient temperature of 23 degree celsius, and the 8800GT is quite a bit hotter on the stock cooler than the 8800GTS 640MB at load. Temperatures were recorded after two runs of 3D Mark 06. For the overclockers, it'll be good if you can go for an alternate cooling solution.

A piece of good news for the enthusiast, the 8800GT comes with similar mounting holes as the the 7900GT/GTX as illustrated below!!! Enthusiast can recycle their Zalman VF700/900 and other similar coolers with their new 8800GT! woohoo!
