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.

When compared to the Black Edition Dissipation cooling system, the Vapor-X design delivers much better results at stock speed and using the default fan profile. Pushing the fans speeds to their limits while the card is overclocked, the XFX solution was several degrees cooler. Surprising due to the large surface area on the Sapphire cooler. The higher clock speeds and applied voltage on the Sapphire HD 7970 3GB Vapor-X impact this number so the real comparison comes down to the stock results.
