    Hi, i just bought the brand new 27" iMac 3 days ago when it came out and I noticed the temps were lookin kinda toasty! Lemme know what you guys think..this is after an online session of Cod4. HD: 119, CPU 108, Ambient 81, GPU Diode 121, GPU Heatsink 121, Mem Controller 131, Northbridge 155, Optical Drive 115, and Power Supply 151. That's all in Fahrenheit. In Celsius it would be 48, 40, 27, 51, 53, 68, 48, and 66. Please let me know if these temps are ok....I tried to download smcFancontrol but I can't get it to work for some reason. Apple tech support thought I should exchange it but she sounded like she didn't know anything on the phone so that's why i'm here....

    None of those seem excessive. My (much older) iMac is running at 40˚C CPU and it has just been sitting here doing nothing for the past couple of hours.

    Edit:
    Why? Why would you suggest this? Tell us what you think the temperatures should be.

    Normal
    My MBP reaches mid 80's low 90's (C) when in boot camp gaming, you are golden!

    Okay, just seemed a bit strange to me, especially when somebody else felt the back of the mac and said it was almost hot enough to burn their hand.

    I think he wants people to exchange their iMacs to generate refurbished units faster.

    I don't think those temps are outside the normal range.

    Those temps are absolutely normal. They are even lower than I would expect after a session of COD4! If you want any consolation, here are my temps on my 24 inch iMac from earlier this year:

    Awesome! I'm no longer worried! =] Wouldn't want my new baby to melt in my hands! Oh, one last thing, does anyone know of a program for Macs that keeps them running at optimal performance? Clears caches and unncesecarry files and what-not? And do I need anti-virus?

    Yes. It's called OS X (ok, ok, not actually a program). OS X runs daily, weekly and monthly scripts to do such housekeeping.

    No.

    No need for any anti viruses or disk defragmenters, not sure about the other thing.

    Try Onyx for maintenance, it's free. I personally just let OS X just do it's thing.

    OSX seems to hold up and keep intact and remain fast quite well on its own.

    If it's not broken.....

    As for your temps - yes they all look well within normal range. My iMac sitting on it's @$$ right now has higher temps all over the board. I suppose that's what a metal case gives you.

    So if mine is cooking away like this - since 06 at least - and no issues here - I'd say you've got a way to go on yours.

    I would like to add although their is no need for disk defragmenters or Anti Virus protection on the Mac OS, if you run Windows through Bootcamp I would suggest some for the Windows side atleast.

    I remember my Mobility X1600 getting to 75° C easily on my iMac Core Duo when gaming. I've noticed that the aluminium iMacs are generally very warm to the touch and especially near the upper vent.

    Macs tend to be built to run hot and quiet unless it's a Mac Pro. We're also using 65W rated E7600 over the older E8435 at 55W and later stepping of 44W.

    Needless panacea answer.

    Thanks, hope you feel better. You reiterating what everyone else said 20 times about temps was very helpful.

    Onyx, among other maintenance utilities, is constantly dragged out as some cure all solution a la Repairing Disk Permissions.

    No one else seemed to mention the actual hardware, past and present, being used or their TDP ratings either. Is there anything else you'd like to add about the iMac's hardware?

    pcs and mac pros get that hot, you just don't go feeling your components because they're in a case.

    I went to the apple store in Sydney here and noticed the new 27" iMacs were quite hot. I asked an assistant and he said you should only be worried if it actually burns your hand. :/

    The Mac Pro has always had a rather impressive cooling system that was even capable of handling the original B3 stepping of the 150W TDP X5365. The new board layout with the CPU daughter boards is a change but it's still impressive nonetheless.


    True enough but we're not touching the components inside the case are we? It's the actual case itself. :p

    Gah, you knew what I meant. The case of an iMac is much closer to the temperature of the components than the case of the mac pro is.

    Did you ever have a chance to touch the older white plastic Intel iMacs? The change to an aluminium enclosure hasn't really brought down the component temperatures but the chassis sure does get a lot hotter.

    Perhaps it might be time to put a warning not to touch your iMac? :D

    Most Silicon Chips will reach 105 Celsius before it dies.

    Sorry, but to me, those numbers look a bit higher. I would be concerned myself. My 24" iMac is currently running at:

    95F CPU
    99F HDD
    92F DVD
    96F GPU

    And I've been working on my Mac for the last two hours so those aren't cool temps.
