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
The cooling solution used on both types of 6800 series cards are heatpipe based cooling solutions that offer decent performance. There are some BIOS updates floating around for the HD 6850 to adjust the fan profiles on the card and lower the noise signature. The HD 6850 really was not the noise producing card even at full song. That honor goes to the HD 6870. Without specialized equipment I can only use my ears as a reference and the noise signature is worse than the HD 5870 and really any AMD reference cooler I have used. This one thing more than any other puts a crimp in the want for additional performance usually gained with a fan speed increase.
