Most likely, a new hard drive would help. Usually, the drives with

drives being too hot - in fact, some improvements have been made that
make them almost as cool, if not cooler, than the stock drive.
By the way - no slot loading iMac has a fan. The optical drive and
hard drives are the only moving objects. Maybe you got an unlucky
noisy drive.
Are you sure there is no fan? I replaced a hard drive in one of these
once, and the noisy whine continued. If there is no fan, then there
must be something on the power supply that starts to go bad and make a
lot of noise. I know for a fact I didn't get unlucky and get a new
drive that also made the whine, because it was the exact same sound.
If the hard drive was the culprit, there would have at least been a
slight change. I also know that it wasn't the optical drive because I
never had a disc in it and the sound began the instant the iMac was
turned on and continued until shut down. Any ideas?
Peace,
Todd
I know there is no fan, unless somebody "hacked" one in. None came out
of Apple with a fan. If the whine was very high pitched - and not
something that stopped when the hard drive spun down, then it could
have been part of the high voltage circuitry making the noise. This
would be a fainter noise - in some cases barely audible.
It would be hard to tell without being in front of the machine.
