    Hi all,

    I bought my first mac this summer (iMac rev.B). Things have been going well, until lately. I noticed that my fans weren't running very often, so I downloaded a CPU temperature monitor from ministat. It was registering close to 200 degrees, and the computer would shut down after about an hour. I took it to Apple and they replaced the logic board and the power supply - thank you warranty. I got it back to school today and the temperature meter is still at around 185 degrees after just booting up. What's wrong and what do I do now?? Is the temperature meter right?

    Does it feel hot to the touch? Is there a reason it could be this hot (working it hard with little ventilation)? What's the temperature monitor called? :)

    I'm in a dorm room that's slightly warm, but it's not too bad - prolly around 65-70 degrees.
    It's been on now for about a half hour and it's pretty warm where it says iMac, but not hot.

    This is so frustrating...

    Also, are you running Tiger? Did the shop dump your preference files? There have been reported issues with McAfee Antivirus and overheat on Tiger, if you happen to have that installed.

    And maybe look through VersionTracker for a different monitor. :)

    Yeah, I have Tiger. I don't know how to dump the preference files - please help. I don't have McAfee - I think I have Virex b/c my school makes me, but I don't think it's running.

    Use Spotlight to find something with the name of your temperature monitor (whatever it's called) or an abbreviated version and the term PLIST. Tell us what you find. :)

    I think 160°F is about normal for medium usage. Is the machine acting strangely? Oh, and you didn't find a PLIST file with stat or mini in it? :)

    found it:

    widget-com.pdashock.widget.minicpuheat.plist

    I thought the temp should be lower than that - that's why I was worried. It wasn't acting odd - I just wanted to make sure that the new parts were helping.

    Nice find. :)

    Now remove it from that folder and restart to reload Dashboard. A new default version of this file should be created at the expense of your preferences. You can keep the old file if you want to so that you can get your old settings back by replacing this newly created file with it and restarting again but I think that's pretty pointless considering there are so few preferences attached to it. So, in other words, just delete it. :)

    I had virex (also thanks to my college)for a while on my powerbook and it used up the entire CPU all the time even when I didn't think I had it on. Open up Activity Monitor in the Utilities Folder. Then change the Dropdown menu from My Processes to All Processes. If something like Vshieldcheck is using up a ton of CPU, you may have your culprit.

    The miniStat2 website says the processor should be under 80 degrees C.
    I also have a rev B iMac G5 and I'm getting similar temp readings. I think it will be fine.

    Thanks :) I didn't have my Apple with me - therefore, no conversion widget :(

    You're still running it very warm so keep an eye on it. :)

    There is one on the motherboard, opposite (under) the CPU. Unfortunately, Apple doesn't provide a driver to actually read this temperature sensor.

    Also, the hard-drive has a temperature sensor (assuming you still have the original Apple drive or another drive with a compatible sensor), which the 3rd party TemperatureMonitor.app can read.
