The boost clock speeds of the Pascal GPU from NVIDIA cycle the boost clock speed up or down as you hit power or temperature targets. I saw this with the Founders Edition cards and it happens on the MSI cards as well. The key here is that MSI's Twin Frozr cooling design is more effective at keeping the temperatures low and the clock speeds high to increase gaming FPS performance. It's a strategy that works. Using large Torx 2.0 fans with dispersion blade technology on the ball bearing fans, there is an increase in airflow of 22% over traditional fan blade designs. Couple that with the large heat sink with 6mm and 8mm direct contact heat pipes and you get an excellent cooling design that keeps temperatures in check, even under a heavy 3D load. Both the GTX 1080 Gaming X 8G and GTX 1070 Gaming X 8G showed significant cooling performance gains over the Founders Edition cooling solution, with much less noise. There is no doubt that MSI's Twin Frozr VI technology is a step forward in cooling performance that shows tangible results.
