my fan on my iMac is noisy
My fan on my iMac is noisy - any ideas how to stop it ?
iMac, Mac OS X (10.7.3)
What kind of noise? Rattling could be dirty and unbalanced. Squeaky could be bearings starting to go. Going at full speed indicates it's either overheating or it thinks it is overheating. The latter can happen if the system software monitoring temperatures crashes and the fans automatically go into safe mode. Restart the computer and see if it clears up, or more trouble shooting is necessary.
I'll have to let an iMac expert take over from this point since I have a desktop and it's easy to open up and clean parts.
