Temperatures are absolutely fantastic on the ATOMIC, and that's even more impressive once you factor in the pre-overclocking on the card and how quiet the cooler is.

Our guess was that Sapphire had bumped up the voltage - and wattage, therefore - on the card to hit the specified core frequency of 1,000MHz. The power-draw numbers bear this out to a very small degree, we suppose, as it draws 9W more than a default-clocked card. The provision of an eight-pin connector is more about Sapphire playing it safe, it would seem.
