I have an AMD Sapphire 6950. It is about 2 and one half years old. I have noticed in the past few months that when I am playing games it makes a resonating noise. Even a simple game like League of Legends, a game with low demands, causes my card to make this noise. Thoughts? * I periodically clean my case so there is no dust build up. * Here is the exact sound: If what this guy says is true this will be my last Sapphire card.
