I got my iMac back in december. When I first got it, I was so surprised at how quiet it was. More than 6 months later, however, the sound of the fan is starting to get to me. Even when my imac is just idling, the fan is blowing noticeably louder than it use to. Maybe I just got use to it being quiet that a little loudness is a big surprise. Is this a common problem? Is there anyway to make it quieter (cleaning, etc)?
Also, is it better to put my computer to sleep when not in use, or just have the display turn off?
