    Exclamation Mac Desktop overheating
    Hello I own a newer Mac desktop that gets very how after being used for a long period of time (like 2 hours depending on what I'm doing) I was wondering if this is normal and how hot it would need to get for damage to be done?

    Your mac knows when it's too hot. It is designed to run up to a certain temperature, designed by apple engineers. If it gets too hot, it will shut its self down. There is no need to worry about the temperatures of your computer.

    The 'too hot' threshold is arbitary. If it's running its fans at full speed all the time, trying to keep cool, something's not right.

    Also, running at very high temperatures (but not deemed high enough for damage by said Apple engineers) will cause solder joints on BGA chips to fracture over time. A common failure mode for many logic boards on both Mac and small form factor PCs.

    I'm not sure if my computer has fans because i never hear them, and Dutchlimits I am not sure how to find out what my cpu gpu temperatures are, but it's hot enough to hurt my hand not so much that i have to pull it away though.

    It definitely has fans, although they're very quiet when the computer's not doing much as their speed is temperature controlled. When you do something CPU intensive like encode a video, you should hear them spin up.

    This neat widget will tell you the temps:

    iStatMenus 2.0 should help you out. Dont upgrade or update to the newer version as it goes paid at some stage. This is still free. Sits in you Menu bar for your convenience.

    This is the paid .v3 but works the same for this version.

    Dont forget to use the Reputation System if someone has helped you out !!!

    those temps are all well within a normal range. What makes you think it's 'hot' in the first place?

    btw, they all probably just parse ioreg output anyway.

    How 'newer' and what model desktop?

    Have a look at smcFanControl which will speed up fans on an Intel machine. Always helps if you provide the model and operating system.

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I would love to understand this obsession with temperatures. Newsflash: Computers generate heat - and the more powerful they get, the hotter they run. Apple does a pretty good job mitigating the thermal output of their machines relative to the rest of the industry. If you want to see a machine that truly runs hot, I'd submit my 2003 vintage Dell Inspiron 8200. Relative to that machine, my i7 MacBook Pro is an ice cube.

    If you've got an overclocked gaming rig, that's one thing.... a pedestrian iMac or MacBook doesn't need to be monitored for the most part. I do agree however, that if the fans are on at max RPM 24/7, there might be a problem - but for the most part, enjoy your machine and allow it to work as it was designed.
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

    The tempatures that I displayed were not at a time that I though the computer was how, I've just never had a Mac desktop before and I was surprised at how hot it was getting. Thanks for all the posts.
