Hi, I've had my Inno3D GF4 Ti4200 graphics card for just over a year now but it seems that the fan is making a lot of noise. I've managed to take a brief look at it while the pc was switched on and the fan seems to spin rather slow. Is there a fault on it? I think I should replace the fan to be on the safe side, but I would like to know how it's done. Anyone?
