Can anyone definitely report if the new 2012/2013 iMac 27" i7 3.4ghz fan noise is quieter than previous iMac models? (primarily when anything processor intensive - exporting video, etc)

The late-2009 27" i7 2.8ghz was/is very noisy when doing anything with video or anything at all that would tax the processor. I always assumed because that quad i7 2.8 chip at the time was the upgrade above the standard higher end i5 model - me thinking it was simply too hot for the iMac internal design at the time where the slower i5 chips wouldn't kick the fan up so hard.   (The previous iMac 24" before that was quiet as a mouse)

 

Before I upgrade a.s.a.p. to new top of the line 3.4ghz i7 27"  I'm nervous that this extra-upgraded chip configuration will run hot, and thus noisy, too.  If so I will step down to the 3.2hz i5 config.

 

This is not trivial for me. Hate to ask this question here but for over 3 years my very fast iMac has been driving me crazy when trying to concentrate while working due to the aggrevating loud noise.   From many threads on many other sites over past 3 years I see I wasn't alone.

 

Thanks in advance to whoever can answer.

    I presume you're talking about the fan noise when you're doing some heavy graphics work; under normal conditions, the drive is pretty quiet. Even upgrading to a hybrid drive won't get rid of the fan noise.

     

    In short, count on the same fan noise as before.

    My late-2012 27" i7 3.4GHz 32GB DRAM 3TB Fusion drive iMac is much quieter than my mid-2010 27" when performing the same tasks.  The 2012 also runs extremely cool.  My 2010 is always warm to the touch and gets very hot rendering video.  My 2012 is normally cool and just gets warm when rendering video.

     

    It is a sample size of one, so my experience may not be the norm.

    My new iMac 3.4 Ghz i7 is definitely noisier than my 2009 iMac 24" Core 2 Duo I replaced.

     

    My 24" was essentially silent. The new 27" i7 has a constant, noticable hiss. Sounds like fan noise or air movement to me. A bit annoying, but I hope I'll get used to it.

    Correction to my previous post. My fans are OK. I had transferred smcFanControl.app from my older iMac. That's was apparently causing the fans to run faster than normal, hence the noise. I removed smcFanControl.app, and my new iMac is, thankfully, very quiet.

     

    Love it.

    My 27" 3.4 GHz Intel Core i7 arrived monday.

    It is QUIET, thankfully. I'm one that is distracted

    with fan sounds.

    I love this iMac.

    I just upgraded from previous 2012 gen Imac 27" core I7 to a new 2013 one.

    And yes it has a much more louder fan noise when processing video and doing high and rendering.

    But...on daily work its more quiet and the temperature is cooler then the previous 2012 gen.
