Please excuse me for bringing up a subject that must have been beaten to death long time ago but: My wife has a 17" 1.8Ghz G5 iMac with 64MB VRAM (so I believe its a rev a), and the fan is always ON. The computer has less than 1 month left of the original warranty so I want to do something before it expires. I was at an AppleStore last week and they said bring it in and well fix it, it takes 4 or 5 days - Sounds good! Is it as simple as that? Do they change something and it becomes quiet? I really hope so! Please any info will be appreciated.
