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 1920x1200 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 stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will be a 20 minute cool down with the fan speeds left on automatic in the stock speed testing and left at 100% when running the overclocked idle testing. For load testing the GTX 580, I will use Crysis Warhead run at 2560x1600 using the mainstream setting with 8xAA looping the Frost benchmark scenario, as I have found this to put a load close to that of Kombuster on a video card. This is needed as a way around the current limiting ability of the GTX 580 when it detects programs that put an unrealistic load on the GPU, which Kombuster does.

Lower = Better
When run at the default clock speeds and voltage setting, the ASUS GTX 580 delivers numbers almost identical to the reference card. When overclocked by using the voltage tweak capability in ASUS Smart Doctor, the temperatures increase by a large margin as you still need to keep the three billion transistors cool. Even so, the ASUS GTX 580 is 15 degrees Celsius cooler than the GTX 480 when you put the screws to it.
