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 15 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 for overclocking. The idle test will be a 20 minute cool down with the fan speeds left on automatic.

Lower = Better
At stock speeds, the Black Edition 6850 was about the coolest running card under load - at 62 degrees Celsius. Under an overclocked load, the temperature only increased by 6 degrees Celsius with the fan bumped up to 100%. However, I should reiterate that this is with a serious bump in core voltage to reach the 'over 1GHz mark' on the core. The cooling solution is not the quietest on the market, but is markedly better than the cooler on the reference cards.
