Temperature testing will be accomplished by loading the video card to 100% using MSI Kombuster, which is paired with MSI's Afterburner overclocking utility for temperature monitoring. I will be using the stability test set to a resolution of 1920 x 1200 using 8xAA. I will use a fifteen minute time frame to run the test ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the first test, with the fan moved to 100% to see the best possible cooling scenario. The idle test will be a twenty minute cool down with the fan speeds left on automatic.

Lower = Better
While both of these cards are the hottest in the lineup, you are also going to see that they both were able to reach higher clock speeds than any of the other cards. For the HD 5670 Ultimate that has passive cooling, only being a few degrees hotter than the other cards is pretty impressive.
