Hi all, Just picked up my Retina iMac not even a week ago, and apart from one small thing I'm completely in love with it....that one thing would be the fan noise. When I first took it out of the box and started playing around with it, it was dead silent. But the very next day, and every day since, the fans have been running, audibly, even at idle. I can close every program or start the thing up from hours of being off and the fans still kick in instantly. I do a lot of writing in a silent room so this is both noticeable and bothersome. Is this something I have to live with or can I expect an update or software adjustment to fix this? Thanks!
