My Gainward GTX 770 phantom 4gb has three fans. As you can see in the picture, only two of them is operating at high speeds and the temperature the two go by are 88 degrees celsius. The middle fan is operating at low speeds and are operating by a temperature of 46 degrees celsius. The temperatures are way to high, and when I had been playing Battlefield 4 for about 15 minutes my pc restarted witch it has never done before. When it booted up again I tried looking it up on the internet and my pc restarted after five minutes. I downloaded furmark and tested, and after a few minutes it restarted again, the picture is from just before this restart.
