MSI GTX 970 Gaming 4G Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine Heaven Benchmark Version 4.0, with MSI Afterburner 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 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 twenty-minute cooldown, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

MSI has equipped the GTX 970 Gaming 4G with its latest cooling solution and newest iteration of the Twin Frozr package, labeled Twin Frozr V. Having seen what the Super SU Pipe-equipped Twin Frozr V solution was capable of on the GTX 980 Gaming 4G, the expectation here was to see the same or better performance based on the downsized core. What we get is that MSI has tuned the card to run at a certain level while the cooling solution is controlled automatically. That level is in the 60-63 °C range. This makes it one of the coolest running cards in the comparison field.

Cranking up the fan speed to 100% allows the Twin Frozr V heat sink package to do even better when overclocked. This cooling performance is impressive when you look at the clock speed increases over stock that this card is capable of running. Normally running the clock speed up comes with an unwanted side effect: increased noise. Not really so with this solution from MSI. The configuration of the fan blades and deflectors in the aluminum heat sink fin array allow higher pressure airflow to linger in the heat sink longer to pull more heat out. The truth of the matter is that the noise levels delivered at 100% fan speeds cannot be heard outside my chassis in a normal household. A truly impressive feat while at stock speeds, but even more so when the fan speed is cranked up.
