Temperature testing will be accomplished by loading the video card to 100% using Crysis Warhead with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA. I will use a 10-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 be a 20-minute cooldown 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.

True to Sapphire form, the large heatsink performed admirably in the thermal testing. The two large fans were able to keep the card running cool at barely audible noise levels. When cranked to full, the noise level went up a little bit, but not significantly, and the temperatures still dropped like rocks even at the high overclock. Great performance here.
