    I just bought a brand new imac
    running 10.5.7
    3.06 Intel Core 2 Duo
    4 GB 1067 MHz DDR3

    i downloaded Handbreak to rip some of my dvd's and put them on my external hard drive

    as soon as i open handbreak and start ripping a dvd, the fans in my computer start whirring away, pretty loudly

    i downloaded the istatnano widget to check my fan rpm's and temps

    While Running Handbreak:
    CPU Drive - 3605 rpm
    Hard Drive - 2408 rpm
    Optical Drive - 2195 rpm

    HD - 57
    CPU A -46
    CPU A - 80
    GPU - 53
    GPU Diode - 48
    GPU Heatsink - 47
    Ambient - 27

    is this ok? is there something wrong?
    the fans are just so loud

    any help would be appreciated

    Everything looks fine and dandy.

    Ripping DVD's puts some stress on the system, so expect higher temps and the fans to kick in.

    In my experience, most Apple fans are loud. And when it gets really hot, expect them to start running around 6K rpm as well as even more noise.;)

    yes, i'm in need of some help!

    My Imac has been whirring for some time now and reaches 110 degrees Fahrenheit and the fans whippin up a storm currently doing 5500 at the HDD (Which i'm thinking is max speed) and 1500 at the ODD & CPU fans.

    Just a little concerned about this, or should I be?? I'd like someone to advise that this is normal but think i'm aiming a little high..

    110F is if anything on the cool side. Really, unless the computer freezes or does a forced thermal shutdown, I wouldn't worry about it. You could make sure the vents aren't blocked physically or clogged with dust, but otherwise, if it's running too loud for your taste, the only solution is to make the room cooler.

    If you're in the northern hemisphere it is summer, after all.

    80 degrees C is on the high side of the computer temperature scale, but is still in a safe range so long as this is only when the computer's CPU is at 100%.
