With the TES 1326 Infrared Thermometer literally in hand we found ourselves getting real-world temperatures from the products we test at load (3D clock speeds).
There are two places we pull temperature from - the back of the card directly behind the core and if the card is dual slot and has an exhaust point we also pull a temperate from there, as seen in the picture.
Considering the Sapphire HD 5670 Ultimate is a passively cooled card, the core temperature is very impressive with it out performing even active cooled models that are lower end.
