My 2011 15" Macbook pro runs at 70-80 degrees whilst playing games, will this cause permanent damage to the computer?

    That's normal. Make sure you use it with no obstructions to the flow of air, and on a hard surface.

    Hey all, I have the MacBook Pro 2011, 13inch. I7. I have mountain lion, about 10 pages of web open, email, thunderbird, Skype and messages. My idel CPU temp is between 100-130F with the fans between 2-5K RPM. It got past 180 last night, and it's been doing this for months now. Any ideas?

    Dunno with this year's crop, but "too much" meant over 100C/212F in the 2011 models. At that threshold the system would go into thermal protection and shut down. The 13" models tend to run a bit toastier than the 15" and 17" both because they have less thermal mass and, more important, have a single desperate fan in contrast to the bigger ones two. Accurate measure of temperature as gauged by the myriad sensors on these things (16 in mine!) is best obtained with Marcel Bresink's Temperature Monitor. Free and updated to the latest hardware.


    I do not think the minuscule "feet" on these computers are enough to guarantee adequate airflow underneath, so I always use a laptop stand or the moral equivalent*. However, a passive stand that just lifts the Mac off the table has proven sufficent, no need for the fancy fans underneath that add to the racket.


    *In a pinch, I've been known to resort to a pair of water bottle caps under the rear corners...
