    Just happen to get my brand new iMac 2 days ago, and the heat issue is worrying me; and this ain't CPU, but it's the GPU instead. Using X Resource Graph and Temperature Monitor, both had the GPU Temp reading around 75-79°C/167-174°F, running non-graphically intensive applications.

    My question is, does anyone with the same batch of iMacs ever experience such problem....?

    Another one will be the NB Temp which hits close to 85°C/185°F....

    Here's the following temp reading taken from Temperature Monitor:

    CPU Temp 59.4°C/138.9°F
    GPU Ambient 71.9°C/161.4°F
    GPU Temp 76.5°C/169.7°F
    HD Temp 51.0°C/123.8°F
    Incoming Air Temp 33.0°C/91.4°F
    NB Ambient 61.5°C/142.7°F
    NB Temp 81.8°C/179.3°F :eek:
    ODD Temp 44.5°C/112.1°F

    On the sidelines, my iMac hasn't given me any other problems as reported by other forummers, my iMac's very quiet though. Even though running proc-intensive apps, the CPU fan's barely audible....

    Is this while playing games or doing something 3d related?:confused:

    See if it goes up when you do something specially GPU demanding. GPU's sometimes do run that hot actually.. especially a 6800GT but it should not go above what it is already.

    yes, apparently it does..... with screensavers alone it hits above 80°C/176°F....

    That does seem hot I'm not sure what is normal for an imac.... but I would not panic at this temp it won't destroy the GPU although it could reduce stablity, I'd worry more if it went over 90C.

    Don't stress it.

    If it ever overheats, contact Apple. Apple will replace it if you are still under warranty. Applecare is also recommended for 2 year extension to your current standard warranty.

    If it is running that hot on non-processor intensive task, it could be a hardware issue. Contact Apple about this issue.

    If you are playing games, it is normal to have high temperatures. Nevertheless, not that high.

    Personal recommendation:
    The temperature readings seems to be wrong. It is absurdly high, well close to melting point. Try another system statistics software to monitor your internal components.
