    I had a lot of rumbling/noisy HD problems with early versions of the previous model, eventually giving up and settling for my MacBook Pro (with cinema display) that has been extremely quiet and dependable. I do a lot of audio editing sitting very close to the equipment and often focus on extremely low-level sounds, so I'm very sensitive to noise from the computer.
    I'm keen to get the new iMac so long it doesn't resurrect that old frustration all over again. Have early buyers been pleased with noise levels and, also, does the fusion drive configuration have any noticeable affect in that sense? Thanks.

    I have a 1TB fusion model and the room that I'm sitting in is completely silent. The only perceptible noise right now is my fingers typing this.

    The only noise I've heard from this machine is that coming out of the speakers, and the fan with its light "whoosh" on a long render out of Cinema 4D that I've done.

    No noticeable HDD noise.

    I have the 1TB Fusion. While running migration assistant, the new iMac was completely silent. The only slight thing I heard was the fan in the Mac Mini from which the files were transfering from.

    1TB fusion, computer has been dead silent. I have not put it through any strenuous testing though.

    Good to know that.
    I'm eagerly waiting my brand new 27" running on a 3T Fusion Drive.

    May I ask you guys whether on the temperature side, everything is OK?

    I mean, I'm really impressed by the thin form factor and hope it will be good enough to cool the beast down :confused:

    12dylan34, did you have any issue during that rendering (that was probably CPU consuming) ?

    3TB fusion here and i have not heard a peep out of it in two days. The only way to hear the HDD is when it is writing and reading random data with my ear right up to the back of the imac lol. The highest temp the HDD has reached is 45deg Celsius. This thing runs cooler then the old form factor iMacs believe it or not :)

    No, nothing to speak of really. The fans got up to about 2900 RPM from their regular 1200 RPM, but the back only ever got a bit warm to the touch. Nowhere near as warm as the the previous generation. You could definitely hear the fan, but it made more of a soft "whooshing" noise rather than the normal electric motor kind of fan noise. A lot quieter than my old MacBook Pro.

    There was a ton of hot air blowing out of the back vent, though.

    That's great news!
    My early 2008 iMac used to be very warm when used intensively, must say.
    Rather happy to hear that the new form factor helps dissipating the heat :)

    Thank you for you answer.
    Happy to hear that it's that silent :p

    I have spent about a week with my 27" and have noticed a ton of noise. I have a high pitch whine and a lot of clicking and grinding from the HDD. Last night when I tapped the chin on the left hand side the noise stopped for a bit then started right back up. I came into work today and checked the forums and it seems that everyone is saying they are quiet as a mouse so I called apple support to see what can be done. They need to see what "processes" are running on mine before they do anything further. So I will have to wait to go home and call back in a few hours. :mad:

    I started a thread about HDD brands in the new iMacs and it seems Apple is using all sorts of HDD's in these things, what is the model of your HDD?

    I just got my brand new 27 today - and just set it up. I'm getting a constant fan noise from what I think is the harddrive.

    Ordered the 3TB fusion - and the 3TB is a Seagate Baracuda as far as I can tell (ST3000DM001) - it's really annoying :-(

    I also have a constant fan noise, not very loud. Is this a regular noise?

    I have a fan noise too, very quiet though. Do those of you that say their iMac is silent really hear nothing at all or just a very very quiet noise?

    Yes, by silent, I mean very very very quiet. It it physically impossible for a fan to make no noise. It just seems un-naturally quiet for how much air it is pushing out. My A/C / Heat makes significantly more noise than the iMac and my central heat and air is not that loud.

    My HDD makes a very distinct, constant noise when anything is being written to it. Ie: Downloading Diablo 3/WoW through the Blizzard Downloader. It's kind of distracting, and definitely annoying.

    I cant hear anything unless i put my ear to the back of the iMac while the HDD is reading and writing. The fan is completely silent at 1200rpm, you can hear it if i use iStat to turn the fan up though.
