    Just got my iMac 27 5k, i7, 395x

    some issues:

    first, it has some inner fan noise like "da da da da da da da......"

    second, the keyboard has different clicking sounds when you click "e" "r" "t" "y" "u" "4" "5" "h", it seems cavity structure under these button. (you need to click it not just press it)

    do you guys has the same issue?

    update: Just came back from apple store, demo machine does not have the same issue,
    please check your machine by putting your ear on the back panel of the iMac, around the fan area, I can definitely hear some "da da da" sounds, it feel likes some stuff keep hitting the fan leaf.
    I am going let Genius bar inspect first, if they don't know what happened inside, I will let apple replace a new one for me.

    Same model. I have no noise and I haven't noticed anything with the keyboard.

    to stop the fan noise.
    shut down. switch off power from mains.
    hold iMac power button while pressing the mains button.
    should solve it

    I can't hear any noise when I was sitting in front of it, but did you put your ear on the back panel?

    I too have noticed that fan noise when the fan is running quietly. Sounds like its catching on something for sure. Not tried any of the proposed 'fixes' but I don't see how it would help.

    I have the 2015 i5 3.3GHz with 395

    I tried to spin it up with smc fan controller hoping it might help, but no difference - when the fan is running at minimum speed there's a definite kind of tapping noise going on around the back.

    Reset SMC multiple times. No difference (nor did I expect there to be, sounds like a mechanical problem)

    I really don't want to take it in, but for the money it ought to be silent :)

    Look this, I have exact same issue and exact same clicking sounds. Since it happened inside the iMac, so it hard to notice unless you put your ear on it.

    Seems like a wire had been pushed up into fans, this will be a problem in the future, so I'm gonna replace a new one.

    I managed to fix my fan noise problem.

    Downloaded SMC fan controller, cranked up the speed of the fan, then, gently rocked the iMac back and forth on it's hinge, I also slightly rotated the iMac left and right. When I put the fan back to the regular setting, the noise was gone. Maybe something was catching that's gone, either way, I don't have to lug my brand new iMac into the Apple store. Happy days.

    I tried almost the same way to fix it, but the clicking sound still there and even never get better. If something was catching the fan, can't be heard directly but who know what will happen one month later? two month later? I would like to just returning it to store, and actually I just did it.

    I chatted with AppleCare and they said that it would be covered even outside of the 14 day window so I'm less worried now, especially now my fan is silent.

    I'm sure you'll get it sorted.
