Over time I've noticed my idle temps of my AMD 6950 have slowly increased since I installed it in early May. I've looked at the card and I honestly can't figure out how to get the fan assembly off so I can swab it out with Q-tips and alcohol. Has anyone taken apart a card like this? I'm sure mine is full of dust, the rising temps are exactly what happened when my old ATI 4850 got loaded with dust.
