    Specifically the hard drive fan runs at 1600rpm and the optical fan always runs at 1350 rpms.

    Those fans run faster than my 2007 24" 2.4ghz iMac.

    Somehow I figured with the cooler running ddr3, 9400M igpu and better cpu architecture that this new 2009 20" iMac would be dead silent because the fans would barely have to run. Or at least be less noisey.

    But that's not the case.

    Anyone have any fan speeds to report on new iMacs? Particularly the 20" model?

    So you can hear the fans when your computer is idle (not running anything)?

    new 24" 2.66

    CPU fan 1200
    Hard Drive 1600
    Optical Drive 800

    Always stay at that speed from what i've seen.

    That's similar to mine except my optical drive is 550 rpms higher. Maybe it's because of the 20" form factor? Less room means heat has a more difficult time escaping?

    Yes. They are always on. It's not loud. But you can hear it when it is quiet.
