Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 3.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 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.

Lower = Better
Having the bonus features of dual heat pipes and dual fans really allow the Sapphire HD 7970 OC to cool well and stay very quiet. The idle and load temps are found to be a tiny bit higher than some of the other leading cards on the market with comparison to performance but at the same time this cooler is whisper-quiet when running in automatic mode. Cranking up the fan when overclocking results in some of the lowest temperatures I've seen!
