iMac Cooling Problems
My Late 2006 iMac's GPU has been acting up lately. It freezes frequently unless I max out the fans, and even then it sometimes freezes if it's hot in the room. I'm in a fairly cool room that sometimes heats up to around 80˚F. I opened it up recently to try to fix the problem and used a vacuum cleaner to suck out the dust inside. There wasn't much dust, but my GPU hasn't overheated in the 24 hours so far I have used my iMac.
Is there some kind of known airflow issue in the 2006 iMac that causes GPU overheating?
