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.

    Wow, you did great already opening it up, they're not easy!

     

    Does that fan spin freely?

     

    Could it be Hard Drive noise, or even the Optical drive trying to spin up?

    I am certain it is not the cd drive, as that died a while ago.  I just ordered a replacement which arrived today. As to the questions about the fan and hard drive, I do not know. I took the cover off the mac and had to disconnect the power button to do so. I also had it unplugged. I am not sure how to check the things you mentioned. I will say that the IT folks who work for the county that my mohter-in-law works with say many computers and other electronics were damaged by having things shaken loose. I am wondering if that may have happened with my computer or if the fan has died of old age. I am not a computer genius, but I can follow directions pretty well. Any help you can give will be much appreciated.

    Can you spin the fan by hand?

    OK. I turned it on with the cover half off. As far as I can tell, the fan in the back, at the bottom (not the top, like I said before!) is the problem. It is a big white fan. It makes a harsh noise, but appears to spin freely. I cannot see any other fans, but I did not open anything. I am going to replace the cd drive. If the noise goes away, I guess that will have fixed it. But, I really think it comes from the big white fan in the back. Your thoughts?

    I think it is likely the fan, but I'd replace the Optical while in there anyway, 2 out of my 3 eMacs opticals died

    I finally fixed my fan problem! I was able to follow some directions on how to lubricate your fan and it worked like a champ! Now have my fan, hard drive and optical drive all fixed up. It is like a new computer. Thanks for your advice and for anyone that needs to, you can get a fan online if yours dies or you can try lubricating like I did.
