After an hour or two of just surfing the internet or listening to music all three of my computer's (imac G5 [als] 2GHz 20", rev. b) fans get pretty up there in rpms. It takes the fans forever to return to idle too, like a half-hour at least. Anyone else with imac G5 experience have this issue? How long should it take for idle?
