    After returning 4 21.5" imacs with yellow screens and hard drive noise, I decided to try a 27" and finally a beautiful screen with no problems, no hard drive noise. I was very happy...untill I started hearing a humming noise that sounds like it is coming from the power supply. The noise stops when I put it in sleep mode. I tried a bunch of things to determine if it was the fans or hard drive and that was not it. I am pretty sure it is the PSU humming all the time. This is the first imac with a perfect screen and now it is humming. I am so frustrated.

    What should I do? Have the power supply replaced or return it for another one and take the chance of getting one with a yellow screen? I am still within my 14 days of original purchase date.

    Live with the humming. I hear it too, but even with this sound (and the dog whistle, which I can only hear late at night with everything else off) it's STILL quieter than a big ugly PC tower or similar.

    I guess that's what they call "as good as it gets".

    I am kind of in the same boat. This is iMac #5 for me and may be the loudest of them all, but at least it has a nice screen. It sill is not too loud, but I think it could be a little quieter. My PC with all the hard drives in it and the fans to cool them was louder. However, my PC will no additional hard drives and the stock cooler was pretty quiet too.
