Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 2.5, 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.

When it comes to a passively cooled card, the thing that should interest us the most is the temperatures. After all, every HD 7750 should perform almost exactly the same, give or take a few FPS for factory overclocks. I was actually pleasantly surprised with the cooler Sapphire provided for the HD 7750 ULTIMATE. While it didn't give us extraordinarily cool temps, it was able to perform almost exactly as a stock cooler would, but silently! The only downside I can see to using the passive cooler, is that the heat is not being exhausted from your case as it would with a stock cooler. However, this can be easily remedied by attaching a silent fan to the cooler via zip ties.
