Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 3.0, with EVGA's Precision overclocking utility for temperature monitoring. I will be using a resolution of 1920x1080 using 8xAA and a five-run sequence 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 involve a 20-minute cool-down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

- Temperature measured in degrees Celsius
With the fan settings left on auto the card operated quietly and the heat sink provided some of the best temperatures! At full load overclocked it barely crested over 50Â°C with Dual Fan Mode. In Single fan mode temperatures were slightly higher â€“ generally 3-6Â°C. This proves that the second fan helps decently.
