Hi;

A few months ago I noticed my iMac acting strange, with my screen not refreshing and everything on the screen would have residual images. I did some searching on the apple boards, and others were saying it has to do with the fan not working properly and overheating. They recommended I used smcFanControl, which has done the trick so far. Is there a permanent fix to this? Something I can replace? Appreciate any info.
