As many of you have seen, heard, or used a Macbook Pro, you know that they run kind of hot. This is partially because of the insane processor speed, and the small size of the casing; even though there are some other mysteries of the heat. But another fact that some of you may or may not know is that Apple purposely underclocks the Macbook Pro so it doesn’t over heat as much, but it still gets so warm it can become uncomfortable to sit on a lap. Well over at the Something Aweful forums, a user has pointed out that one of the reasons the Macbook Pro gets so hot is because of a misapplication of thermal grease. Now you can read the full article with pictures, or the instructions to disassemble your Macbook Pro yourself; but it does appear to have taken the temperature from about 55 degrees down to 39 degrees. This may void your warranty, so take extreme caution in attempting to do this, you do not want to destroy a $2500 computer.

  1. I have never used a laptop that hasn’t gotten to be a little too hot to be comfortable when it is sitting in your lap. About the best I have used in this regard was a 400 MHz Pismo. It warmed up slowly enough that you didn’t really notice but when someone else had been using it and they passed it to me it was a bit uncomfortable.

  2. Anyone near want to start a service that does this? I’m not interested in doing it myself, but I would gladly pay a reasonable amount to have it done by a professional.

    I have a few friends with Macbook Pros and those things get so warm you could grill on them. I mean all laptops and computers get hot over time, my Powerbook gets warm after a bit, but Macbook Pros are insane.

  4. Now does the Macbook GPU automatically clock down with the Mac OS drivers? I was never quite clear on how OSX handled advanced driver features like that.

  5. Well I have a simply solution to your problem. You say that the MBP gets so hot it is too hot for your lap. Why don’t you try wearing pants? Perhaps maybe putting it on a table would be more reasonable? I know they are so handy right there in the lap, but sometimes we have to adapt. It is evolution. Try putting it somewhere else, but try wearing pants first.

  6. Man and all this time I thought *I* was the one getting hot – must’ve been the sites I visited. Thanks Tanner, now I know its just the MBP. Now I will have to wear pants…

  7. It’s a rule of mine to always wear pants while computing. I also leave my MacBook pro on my desk while I work. Even still, it’s hot on my hands when I type. Don’t tell me you expect I should wear gloves as well as pants.

  8. This doesn’t make sense. If the MacBooks are running too hot because of a grease problem, that means its fixable under warranty. You don’t need to crack your case – if a Macbook with proper grease is running at 39 degrees, and one with poor application of grease is running at 55, you should justbe able to show apple that your macbook is running at the higher temp and they’ll take it back.

    Why perform the surgery?

  9. Well, Brad, the thread shows that Apple’s own manuals call for too much grease, so even if an Apple certified technician reapplies the grease, if they follow the instructions they’re given then the problem will persist.

    The problem here, or so it seems, is that Apple is overdoing it. The dude who made the thread apparently spoke with a “genius” at the Genius Bar and the “genius” said that he would do his best to pass the information on to the appropriate people. This, combined with it being all over the internet, is bound to produce results if a change is indeed necessary

    i am an apple certified technician. taking apart the machine will not void your warranty unless you fuck something up. but if you dont know what you are doing, you probably will fuck something up.
