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.

Cooling on the GTX 670 is indicative of the power efficiency by the smallish heat sink used to manage the thermal load. It does well enough to keep the GPU well below its 98C thermal threshold. NVIDIA has worked to reduce the noise signature of the fan by incorporating an acoustic dampening material and rewriting the fan speed control algorithms so there is a linear increase in fan speed rather than ratcheting up in large steps.
