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.

- Unigine Heaven 3.0 1920x1080 8x AA
- 5-run sequence
- 20-minute idle duration
- Temperature measured in degrees Celsius
The cooling performance delivered by the GTX 660 DCU II TOP is almost 40 °C below the thermal threshold for the GK106 core when overclocked. At stock speeds the load temperatures are comparable with the GTX 560Ti yet still 10 degrees higher than the HD 7870 Flex.
