    Hi All

    So I am able to read the temps of my CPU, RAM ,etc.

    Is there a general rule of thumb where temps for CPU and RAM should be a concern. I know they can get hot, but at what temps for both should be reason for concern.

    me too

    I too am wondering what a good temperature range is.

    But I also need to know how you measure it. I'm assuming it has something to do with Mac diagnostics, but any light you can shed would be great. Thanks.

    iStat Pro.

    It's a widget on Apple's software download page. It's probably just in the 'most popular' list. Go there and get it. It's great.

    Give istatPro a shot. If that doesn't work, try Temperature Monitor.

    Both are available for free on Mac Update.

    I second iStat Pro. Although the program has not been able to read RAM stats on my new Mac Pro, the developer has been great communicating to me via email to find out why it's not working for my machine.

    iStat Pro is nice, but I don't like how its a widget (uses a lot of memory) and how it doesn't display all the temperatures.

    I use Temperature Monitor, which lists most of them, puts a temperature on your toolbar and dock, and allows you to customize.

    There is also a program called Hardware Monitor (payware) that allows you to monitor your temps, hardware, electrical system, fanspeeds, and a few other things.

    No one yet seems to know what are considered bad temps yet

    I would get concerned if the temperatures for the CPU are above 60-70C I don't know what that is in Fahrenheit. Then for the memory it should get above 70C Thats just about what i would think it would be. The CPUs are rated for something like 80-90C then damage starting around 100-110C However it shouldn't get that hot.

    If you see smoke coming out of your computer, that's a bad temperature.

    (Actually, Temperature Monitor will say what the specified upper limit of your CPU(s) are.)

    Your case will start to melt at around 1200 degrees so I would say that that is a bad temperature, but I don't actually know what the highest tempurature that it is safe to run it at is.
