    Hi, I just recieved my 1st mac today and I was wondering if any users with the updated ibooks know what the temperature should be? I have downloaded a the cpu heat widget and right now it's showing 46 C, but earlier it was up to 50 C. Just wondering if anyone has some info on this. Thanks alot.

    As far as I can tell, your iBook is normal. I have the new updated iBook and it generally runs between 46-50 C. I have been running off the power supply, but my energy settings are actually the same for the battery and power supply.
    My googleing shows up the same average temperatures.

    This is something I've been wondering about too. I'm a long-time Mac user, but purchased my first ever laptop, a 12" iBook, about a fortnight ago (just a few days before the updated models were announced, but of course I'm not in the slightest bitter about that :))

    Anyhow, I've installed a Dashboard widget to keep an eye on the processor temperature, and it appears to be getting surprisingly hot. It fluctuates, but I've seen it go as high as 65c (earlier this evening) to its current temp of 55c. Mostly it seems to hover around the low-to-mid fifties.

    That said, I haven't noticed any ill effects and my 'Book just ticks over as normal, but are these temperatures safe? It does seem unusually warm...

    A couple of things...

    Remember that Dashboard in it self is very CPU intensive and will increase your temperature when in use, try another temperature monitor. ;)

    Also, the fans doesn't kick in until the CPU gets 66-67°C, so unless you constantly have the fan on you shouldn't worry too much.

    Still 55-65°C in typical use seems a bit high (min typically runs at 48-52°C in normal use, including Safari and iTunes/AirTunes, two notorious CPU hogs). So, are you running Folding, SETI, Limewire, Bittorrent or similar, all the time? Is Classic running (look for a TrueBlueEnvironment in Activity monitor or check out the Classic preference pane in System Preferences, if it's there)?

    Edit: Maybe your CPU isn't that hot after all... :eek: My iBook used to run at about 50°C, but that was before I cleaned up a bit, and now it actually runs at 55-58°C. Not too unlike yours...

    My G4 iBook 12" 1.2 is running at 63-69 C recently. It has been running in the late 50's but now has been getting hotter and the fans started kicking in. I'm running the same applications (Terminal, Mail, Safari and a Java app) but for longer periods of time..... it now my standard daily use machine instead of being a supplemental to my Windoze machine.

    I'm using thermographX and it's the CPU Bottomside that's running in the late 60's....... is the extended use likily to cause the temp rise???

    EDIT: Interestingly after a reboot (for an new install) my CPU temp dropped back to the late 40's and has been ok since....... looks like either something was running and causing this or the machine had gone a little loopy.... it does feel cooler to touch now.

    Right now my PB is hitting the 60c mark and all I am doing is looking at this site and listening to iTunes (cbcradio3). Just as I noticed the temp I propped the PB up with a book. Should have done that in the first place.
