Hey my graphics card is overheating and I have no idea how to stop it. It says the fan speeds are at 20% and that it's at 52 degrees celsius. I also have a case fan that is not moving at the right speed. This problem came out of nowhere and I'm completely lost on how to fix it. I have an AMD radeon HD7950 3GB graphics card. Any help will be greatly appreciated. http://imgur.com/OosLXMy this is a screenshot of TechPowerup GPU showing what i just stated.
