I'm not complaining about the amount of sound my new 2012 iMac makes before I say anything else. I've seen lots of threads about how noisy or quiet the iMacs are and honestly I have no idea what noisy is and what quiet is. I don't believe any computer is totally silent, even an all flash MacBook Pro because they have fans and if if they are spinning at the lowest speed they will make a noise. That noise probably won't be audible if there is other noise in your house, room or even outside but it will be audible if you sleep in the same room at night. because there isn't any noise then (where I live there isn't but if you live in a city that may be different). So what is quiet? And what is noisy?
