    Hi, I purchased the new 27" iMac (3.2Ghz 675mx) 30 November and it was delivered on December 21.
    I have two issues:
    - is noisier than the previous model
    - even if In the room there silent as the grave, the internal microphone capture the sound non-existent.
    - when it is switched off, after turning off the monitor, the fans start to run at maximum speed without stopping. I have to remove the power cord from the mains

    That sounds faulty? Perhaps you should get it exchanged.

    Have you tried SMC and PRAM reset? Although pulling the power should have reset the SMC.

    ugh apple needs to get their crap straight, i dont have those same issues as yours, mine is very minor, my computer fan or hard drive sounds like a fridge all rattling and stuff. I dont have any other issues no yellow screen or imperfections. Your machine is definitely faulty call apple ask to speak to a senior specialist, thats what i did they put you on top of the list since its a replacement, you get to keep yours for now till you get the new one. Its very very annoying since they dont have any in stock hence i havent gotten the replacement back, i however spoke with a rep and they told me i should be getting mine at the beginning of jan thats next week so lets hope i get something that works but by the look of things apple is not doing a very good job at sending out machines in good shape. Anyways good luck.

    That's what happens when they push the boundaries of this stuff. Apple customer service has always taken care of me when I have used them, but Apple shrinking this thing down so much I thing is pointless IMO and removing features to do it.

    My Mic does the same thing. But i have done voice calls on it with no problems.

    As for the fans though that is faulty id say.

    the only time mine reved up high was during a full screen game

    My macbook Air does the same thing with the mic. Nothing faulty about that. Can't speak for the fan though. Have you checked for updates? They may release something soon.

    The mic noise could be anything, it is really sensitive. The fans noise could be something you have plugged in (I see lots of cables behind your iMac) try disconnecting of all them.
