Need fan help...getting increasingly louder
I have an old emac. We are in an area that experienced a 5.8 earthquake and recently a 3.4 aftershock. Might just be a coincidence, but since that aftershock, the fan is louder and seems to run all the time. It sounds bad and has never sounded this way before. I have taken the cover off and cleaned inside. It did not help at all. I have read posts about fans, but really am not sure if the big fan I see at the top in back is what the problem is. Please advise. I really cannot afford a new computer, but would be happy to replace a fan, if that is what it needs. Thanks.
