TechPowerUp posted a review on the MSI GTX 1070 Gaming X 8 GB
A quote from the article:
MSI's GeForce GTX 1070 Gaming X is an overclocked custom-design variant of the GTX 1070, which is whisper quiet even during heavy gaming thanks to its dual fan TwinFrozr thermal solution. We overclocked this $439 card in our review too, where it's even faster than the GeForce GTX 1080.MSI GTX 1070 Gaming X 8 GB @ techPowerUp
