From what I noticed the fan even at 1200 RPM is multiple times louder then the HDD to the point where the HDD might as well be silent since it's drowned out by the fan. Keeping in mind the fan is very quiet like you described.
I realize all HDD can be different this is just my experience.
Hmm, then out iMacs has to have a different amount of fan noise. I think that can be likely though, because my 2008 imac makes a lot more fan noise than my 2012 iMac. And also my 2012 imac did make a sort of "flaff-flaff" propellar sound in the beginning, but it started running smooth after a couple of weeks. But, I sold my Lacie 2big HDD because the noise was so loud and I felt it ruined the whole iMac experience. I bought a Lacie fanless d2 thunderbolt instead. And even if its fanless, it still makes a LOT more noise from the HDD than the iMac (its night and day). So, im pretty picky when it comes to noise, once the HDD goes to sleep more its almost silent in the room. Sadly though, now I don´t know what external HDD I can buy, I don´t trust Lacie, if not I would consider the New 2big thunderbolt 2 Drive.
No I don't. That's why I said "you may have an internal hard disk too."
My iMac is SSD only.
It's pretty damned near silent and easily the quietest computer I have ever owned other than an iPad! ;-)
The central heating in the house makes FAR more noise, as indeed does my laptop even when idling. It really is brilliant.
It just grates a little when people say it's absolutely silent. I hear that said often and it simply is not correct.
You are right, there is some noise. But I also think it depends how lucky you been with the fan. just a slightly off balanced fan would make a lot more noise. Mine is almost silent, and once it start up the 2000 rpm hard working mode, its just clear brease, absolutely no fan flacking sound at all. But in general its barely audible. And, as I mentioned above, I´m very picky with noise, I tried multiple external HDD´s, and Im still on the lookout for a proper one. And I even sent back my Wacom tablet because I could hear a high pitched whining sound from one of the led lights
So all in all the late 2012 iMac beats all the computers I´ve ever owned.

Yes, agreed.
I am constantly tempted to move to 2.5" external disks because they are so much quieter. As it is, I unmount my external media when I am just working on proposals and stuff, so it powers down and is silent. Otherwise the external hard disks are WAAAAYYYY more noisy than the iMac.
I am tempted with this:

It's two 2GB 2.5" disks in a single enclosure running Raid0 (transparently - it just looks like a 4TB drive as far as OSX is concerned.) The Raid0 bit is concerning for reliability reasons (twice the risk of failure), but I figured I might buy two and run the pair in Raid1. So "mirrored stripes, aka Raid 0+1", which is reasonably reliable. They should be quiet too, and under my desk hopefully not audible.
Thanks for the tip, sadly though its a small storage. Im very curious about the new Lacie drive. They do market it as nearly silent. But I read that before from Lacie and then bought it and the noise level was horrible. So I wish there were a review were they focused on noise.
If anyone here bought it, I´d love to hear their experience.
This is the product Im referring to:
