Hello, I have a Quad G5 with the 7800GT graphics card. The machine itself is super super quiet thanks to having the single pump LCS. But for some reason the fan on the 7800GT is making quite a bit of noise. Is there a way I can lubricate the fan bearing on it, or should I just get a new card? I was thinking of getting the 7800GTX which is a much faster card and has beefier memory on it of 512MB. Someone please advise, as I am thinking of putting back in my G5 the 6600 as the noise from the fan in this card is driving me crazy!
