    I recently got my 3.2ghz mid 2010 21.5' imac. I noticed that its been getting really really hot on the top on the top left and right corners of the computer. Usually i am watching tv series (.avi) files on it using quicktime and vlc and i checked the temps reaching these as follows
    HD 54
    CPU A 50
    GPU diode 71
    GPU heat sink 68
    memory 58
    optical 51

    and the fans are at
    CPU fan 1470 rpm
    HD 1099
    optical 1000

    are these temps okay ? or is htemachine over heating for the activities i am doing, usually i amjust msning, and watching tv series

    You do know that since these iMacs are made of aluminum they will (and should) get hot? This is because aluminum conducts heat in a different way to plastic. Anyway, here are my temps (I have one Firefox-window open and Spotify is playing a song):

    HD 47
    CPU A 53
    GPU diode 57
    GPU heat sink 54
    memory 52
    optical 41

    Video really taxes a machine, if it doesn't cool down somewhat afterwards is when you have an issue.

    The aluminium iMac's act like giant heatsinks - especially with the components in such an enclosed space. And since heat rises, its no surprise that they feel hot to touch - therefore, stop touching your iMac :p I know it looks all pretty and stuff but you don't want to burn yourself ;)

    Definitely normal. The CPU fan's RPM is also higher than idle, showing that the system acknowledges that the temps are running hotter, and is cooling the machine down. Don't worry, and enjoy your new machine.
