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 bumped up to 100% when running the overclocked idle and load testing. For load testing the GTX 580 and GTX 570, I will use Crysis Warhead run at 2560x1600 using the Gamer setting with 8xAA looping the Avalanche 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 500 series when it detects programs that put an unrealistic load on the GPU, which Kombuster does.

- 20 minute idle duration
- Temperature measured in degrees Celsius
Lower = Better
With the card controlling the fan, the temperatures delivered by the GTX 570 were excellent. The idle temperature was the lowest of the NVIDIA cards in this test, while the load temperatures were right in the middle of the pack. The low to mid 80 degrees Celsius range seems to be where the fan speeds start spooling up on all the cards tested. When the fan speeds are ramped up for the overclocked testing, the GTX 570 delivers the best temperatures of a Fermi-based card to date.
