UMBA-13 CPU temp reaches 80c using Skype

Discussion in 'MacBook Air' started by calvol, Mar 20, 2011.

    On a Skype call, the CPU temp goes from about 43C to 80C, and the fan goes from 2000rpm to 3850rpm. Is this within normal limits?

    Yeah, my MBA starts cooking with skype video calls also.

    just curious, does this happen to all MBA users? i was seriously consdiering and saving up for one, but i wanted to use skype frequently since my girlfriend and i may have to split up for medical school
  4. macrumors 6502a


    This is a normal temperature for any CPU under stress. 80 degreese Is nothing

    Welcome to Apple lol..

    Yeah, using the facetime camera is a big CPU hog it seems.

    I would personally suggest coolbook to underbolt your processor. Many people state it does a job on performance which is completely false. It keeps your processor cooler and extends battery life

    There's nothing keeping you from using skype. So what if it gets a little warm? Just use it and stop worrying, that's what I do.

    I also second the suggestion above. I use coolbook on my MBA and while it still gets warm when using skype, it does not get hot enough to kick the fan up to full speed anymore where as before coolbook it was at full blast after a few minutes.

    i have the exact same thing with my air, when using skype the cpu stays at about 75 degrees with the fans on 4000RPM. i use skype alot, so if i knew this was the case i might have bought a MBP, which i assume would get less hot (better cooling). does anyone know if the other macbooks also hit these temps when using skype?

    80 degrees Celsius for a CPU is nothing? :confused:
  11. macrumors 6502

    i'm pretty sure the cpu being at 80 degress will have a pretty big effect on the lifespan of the computer? please tell me if thats not the case... then i can stop worrying ;)

    That's 176 degrees Fahrenheit lol!

    i play starcraft on my air and it gets up to 80 all the time...nothing over though

    o ya and check out the apple official forum...they state that it is normal
  14. macrumors demi-god


    It's perfectly normal for a Mac and well within normal operating temperatures. If your Mac gets too hot, it will automatically shut down to prevent damage. This won't happen unless temps reach around 105C or more.

    thank you...nobody listens to me haha
  16. macrumors newbie

    No I listen. It's just I know 80 is a little too hot for my i7 to run at home on a regular basis, so I was kind of surprised to hear 80 on a laptop being described as "nothing".

    Desktop CPU's have very different TjMax's than laptop CPU's have. For the most part, a laptop Core 2 Duo will have a TjMax of 105˚C.

    In contrast, desktop CPU TjMax's vary, but they are around 85-95˚C

    80C for a CPU IS hot, don't let anyone tell you it's "nothing" that said, 80C is still within Intel's operational specifications. Heat will degrade components over time too, so the same cpu running at 60C will last longer than one running at 80C. That said, I've been around CPU's for many years and my experience is that even at the higher temperatures, the CPU's physical life span will still outlast their usefulness. Meaning, you will more than likely have already moved on to something else by the time you get a failure due to heat. The bigger worry would be thermal compound drying up.

    Once my CPU gets cooking...I make an egg on the back of the MBA....Tasty

    Uhm. The point of the thread is "is this normal" yes it's normal not is it hot. Of course 80 degrees c is hot. If it's within the normal operating temperature of the CPU it is normal! And that being said within a normal life span of the CPU it is highly doubtful it will degrade or fail any time soon

    components have normal operating temperatures for a reason its normal for them to be operating within those temperatures...cpus shut down as a safety measure to prevent damage due to high temperatures...the c2d i believe is 105 from what i recall, this is 25 degrees higher than 80 degrees. do you realize how big of a jump 25 degrees c is?..it is common sense that electronic components degrade over time, weather its operating at a high or low temperature.
    don't let posts like above scare you

    Perhaps you should read a little closer instead of getting defensive and essentially repeating what I said.

    80C is hot, no ifs ands or buts about it. Very few CPU's run at 80C, even in laptops. Yes, it's within intel's spec (which I said) that doesn't mean it's not hot. (notice I did not say TOO hot) I also did not say it would fail soon, I said if you compare a CPU running at 60C vs one at 80C chances are the one running at 80C will fail first but that by the time it would fail, you'd have moved on already.

    Are you disagreeing with that? Do you really think an 80C cpu will run at 80C for just as many years as the same CPU running at 60C? I'd like an answer to that question please. Because if you do think that, you don't know what you're talking about and shouldn't post, and if you don't think that, then you're saying the same thing I said, and your above reply serves no purpose.
  22. macrumors 6502a


    I agree that the component running at a hotter temperature will degrade faster but thats nothing to worry abou unless you are planning on using the computer for a decade

    And what exactly do you mean "run" at 80 theres a difference between running and reaching that temperature when under extreme stress

  23. macrumors 65816

    Nothing to do with Apple. Everything to do with Skypes crappy code.
  24. macrumors 6502a


    Not entirely true; MacBooks are designed for aesthetics as well as performance, but generally will sacrifice performance for aesthetics. Performance here is heat dissipation, which almost EVERY Mac I have had sacrifices a bit for. Currently I'm ripping a DVD and my C2D is cooking at 100 degrees C, and I don't doubt that the Air generates a lot of hot air when running at full. Thankfully, like has been said already, this isn't that much of a problem, especially if you plan on upgrading your computer at least once in 5 years. These modern processors (especially in laptops) can get pretty hot without much damage. Now, if you're getting over the rated specs, then you're in trouble.
