I got my iMac in November. When I first ran it I thought I had a noisy one but, after a couple of sleep cycles it quieted down considerably. Now it really is 'whisper quiet' I sleep mine every time I leave my desk for more than a couple of minutes. I just touch the power button as I stand up. I never shut it down or just leave it running. I find if I don't do this it tends to run louder. Sleeping it while away keeps it quieter while I'm using it. Works for me. All the best, Tom
