    Exclamation Safe operating temperature for a '07 Macbook
    Hi, I have a 2007 white Macbook. I dont think that the temperatures that it achieves under load are safe but i dont know so im asking you. Ill tell you my specs and then the temperatures i achieve.
    Specs:
    Model Name: MacBook
    Model Identifier: MacBook4,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.4 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 3 MB
    Memory: 2 GB
    Bus Speed: 800 MHz

    The idle temperature is 53 degrees Celsius, which isnt to bad but the fully loaded temp can be up to 115 degrees Celsius. This doesnt seem safe as a normal desktop shouldnt run higher than 90 or so. Yes, the fan is on MAX and i can hear it. If you do not believe me i can post screen shots of it under load and idle. (Load on my computer means watching a 360p youtube video, as the CPU gets maxed out.)

    Thank you in advance

    Specs:
    2.16GHz C2D MacBook w/ 2GB RAM & 120GB HD. HTC Droid Incredible.
    If the computer gets to a unsafe temperature then it shuts itself off.

    It is a little high...... you shouldn't see it get much past 95˚C unless you are blocking the vent and have it sitting on a soft smothering surface.

    Agreed. If all you're doing is watching a YT video, that is way too high. As 6string has alluded to (but is worth re-asking), what kind of surface are you using your MB on? It sure sounds like you're MB is struggling to ventilate properly.

    As above and try some compressed air and try to blow out any dust and such, as its 3 yrs old and they do collect dust over the years.
    You dont comment as to if it has only just doing this or its been increasing over time. But a good blow job on it cant hurt at all

    I find it absolutely fascinating that people seem to believe that Apple didn't take normal (or even exceptional) operation into consideration when designing the cooling system. As though they just "forgot" that computers get hot when used.

    Fascinating.

    Usually agreed chas_m, but in this case we are talking 115˚C (238˚F) while watching a utube video. This is on the unusual side of things, which would lead to the question of smothering the Mac, or some sort of fault, be it dirty fan, etc.
    I have roughly the same idle temp, and when watching utube vids see 65˚C on my MacBook.

    Hi, yes thanks for all the replies. On the topic of smothering the Mac, When i first noticed this i was using this on my wood desk, not on a blanket or such. I did a test and tried it on my bed an the temperature didnt change. Somebody recommended compressed air? What kind of place would sell this and I would just blow it into the vent on the back? Right no as im typing this is sitting in my lap and its running at 42 degrees so thats pretty normal.

    Hardware store for a can off compressed air..... or if you are feeling teckie, and have the tools, or want to get tools, you can go to Installing MacBook Core Duo Fan - iFixit and look at the fan, and clean it.

    then mine must be way to hot because Im using IStat and im getting the 115c under load. Im going to take it into my Mac store and have them take it apart and put it back together. I think maybe the thermal compound or the fan might be worn out. Ill post results when its done

    Just to be sure that anyone who reads this thread understands before they go rushing to Apple.......
    Temp depends on climate, load, and operating environment.
    There are many variables!
    Climate - Temperature, humidity, airflow and altitude
    Load - One or many CPU intensive apps running, flash, etc
    Environment - Are you using the laptop on a clear solid surface, raised surface, etc

    Apple Portables: Operating temperature

    As stated many times, these laptops are designed by Apple to shut down before they exceed safe operating temperatures!!!

    *read the following post!

    Well said. Feel like we need a *sticky* like the "i spilled liquid on my notebook", so people can understand. Im sure we get 10 questions a day regarding this subject.
    If the Mods read this, what do you think ???
    I will post in the suggestions forum as well.

    Just a thought.
    +1 for me .... Anyone else want to + it ??

    Cheers
