Imac makes fan noise when it turns off or goes to sleep
Hello,
I bought a new iMac from bestbuy during the last week of april 2013.
Recently when I turn the iMac off or put it to sleep, it begins to make a loud fan noise at the back above the place where the power goes into the iMac. However, the moment I turn on the computer the sound goes away.
I left the iMac on for a few hours thinking the noise will go away on its own but it didnt. Now I always have to turn off the iMac and take the power out of the wall in order for it to not make noise.
Does anyone know what I can do to solve my problem? I have tried the SMC reset and the Pram reset however it does not seem to do the trick for me.
iMac, iOS 6.1.4
