hello. i have a radeon HD 7870 and have had it for the past couple months, and it seems that whenever i start up a game it emits this high pitched squeaking noise, and the graphics card jumps to about 64C after a couple of minutes in game. i have also started experiencing game crashes, but that has been at the same point in the same game so i will presume that its the games fault, but im not sure whether to RMA it with overclockers, or just wait for it to break. i bought it back in January, so its not exactly old. i would be grateful for any advice thanks a lot!
