Eugh. My poor X300's puny fan started making funny noises and was slowing down. Today it just stopped altogether. I doubt the very small heatsink is enough to cool the chip passively, so is there anything I can do about it? Since it has been overclocked, it can't be returned. And buying a new card is out of the question. As far as I know, there are no aftermarked heatsinks for an X300, so what do I do?
