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.

With Vapor-X in the game, the rules have changed and cooling isn't an issue. At idle it is going to be a bit warmer, but it is by no means too hot. At idle it is also a silent card -- I think anyone can trade these slightly warmer temps for a quiet addtion to the case. Under load is where it really shows off, keeping it cool under the heaviest loads, and still remaining a bit quiet; at least compared to some cards. You can easily overclock without messing with the fan profile at all. It does the job, and it does it well.
