MSI GTX 770 Gaming Testing:
Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 4.0, 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.

At stock speeds with the fans controlled by NVIDIA's latest fan control algorithms, the MSI GTX 770 Gaming shows the strength of its advanced thermal design with the Twin Frozr IV cooling solution. At idle it is three degrees cooler than the reference card and ten degrees cooler under load. In that respect it met the goals of the exercise to run cooler than the reference design. Turning up the fan speed to the maximum level shows that the vapor chamber-based solution on the reference card is no slouch but the MSI Twin Frozr design still out performs it with a reduced margin. Running cool and quiet has been the ongoing mantra with NVIDIA and its partners, and both cards run cool and quiet, yet the Twin Frozr fans do deliver a more pleasing tone to the ear at max speed.
