I own the same laptop, I have it for about 2.5 years now and never experienced such temperatures. During a normal workday, (programming, compiling, git etc) I never once heard the fans spin up. I have a BookArc[1] laptop stand, which is about the worst possible way to keep a running MBP (lid closed, fan slots pointing down) and even with lots of gaming, I have never experienced any problems. Yes, I do clean the fans once a year, but all laptops need that. It goes to show that thermal wise the MBP is actually very well engineered.

I just use them on my lap and have never had heat problems with any of my macbooks. Before I bought my first macbook air I wrote a program on the console that slammed the CPU and left it running at the apple store. When I came back a few hours later the program was still running (100% CPU on all cores) and the machine was still cool to the touch. I then purchased the laptop.

  > I just use them on my lap and have never had heat problems with any of my macbooks. Yes, but have you ever specifically had a 2011 MBP like in the article? It's a very specific set of models that have the heat issue. Mine could easily hit 90C under load (it just bricked itself last week). Which mean it was quite hot to the touch. After I changed the thermal compound, it would hit the low 80s (C) at peak, but even then, it was quite hot.

    I haven't had that model. Apple has clearly had some thermal design problems in the past, but my sense is that they have been resolved in newer models.

      Looks like they may not be. In this article today, some people think the new Mac Pro's issues are thermal related: http://appleinsider.com/articles/14/12/30/apples-latest-mac-pro-continues-to-cause-problems-for-professional-users http://appleinsider.com/articles/14/12/30/apples-latest-mac-...

Right...except for the tens of thousands of people with the 2011 machine experiencing heat related damage to the GPU. Your study size of one doesn't 'go to show' anything at all regarding the MacBooks thermal performance. It shows that you yourself haven't experienced any issues but that's where it ends. I for instance have a 2010 i7 MacBook Pro and it will spin up and get ridiculously hot (too hot to touch) simply watching a 1080p flash video on YouTube. Not the greatest thermal design there with my study size of one :-) What I will say though is that Apple seems to use the Aluminium case as a heat transfer device, so it purposefully gets hot to disapate heat. That's great until there is a fault with the solder being too thin to withstand the planned temperatures like is happening to the 2011 MacBooks with the discrete GPU.

  You are right. I just wanted to share my personal experience, my English writing is not good enough to express that intention... Also, I didn't notice the MBP in the article is a 2011 model, mine is mid-2012, so I guess I can't compare those.

    The chips in the 2012 are significantly cooler running than the 2011. IIRC, the chips in the 2011 models were the first generation Sandy Bridges.
