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 twice the cores used on the GTX 680, NVIDIA had a significant challenge to meet when delivering on the thermal characteristics of the GTX 690. In three out of the four tests the GTX 690 is cooler running than the HD 7970 and is cooler running than the GTX 590 in all four tests showing how efficient the Kepler architecture is. NVIDIA used separate copper vapor chamber-based heat sinks for each GPU eliminating any thermal load stacking seen on earlier dual GPU cards. Even at 100% fan speeds the GTX 690 is quiet by comparison to earlier cards like the GTX 590. The work done to maximize airflow and reduce noise is evident here.
