    I just turned on my iMac today and it is making a loud noise. I have now realised it is the fan which is going at about 3600 rpm (CPU Fan).
    Do I need to return my iMac - or is there an easy way to fix it?

    Thanks!

    Hi there, Applecare had me do this the other day. Their instructions were:

    do a restart from the apple menu
    when the computer reboots hold down these four keys simultaneously: alt, command, p, r
    ..........hold down until the start chime sound rings three times, then let go. Hope that helps.
