Some people have opened their laptops and cleaned off the old Apple thermal grease and replaced it with Arctic Silver 5. A 20 - 30 degree Celsius drop in temperature has been noted in some cases.

Many MacBook Pro owners are so frustrated at Apples apparent silence on this matter that taking the computer apart is the only choice.

It's interesting to compare the temperatures of MacBook Pros before and after removing Apple's thermal grease and the application of Arctic Silver 5. More on the Thermal grease theory can be found here.

You can graph your MacBook Pro's temperature quite easily by downloading a copy of Hardware Monitor and following Phil's instructions. Phil is soliciting temperature graphs from MacBook Pro users that have removed Apple's thermal paste and applied Arctic Silver 5.

  • Apple's resonse - hmmmm

    It is interesting how you mention Apple has been curiously silent
    on the issue. I own a number of macs, and encourage others to
    buy them as well. My most recent purchase is the last
    generation 15" PB with PPC.

    There are extensive complaints about the wireless reception (or
    lack thereof) as well as consistent dropping out of connectivity
    at 4 feet from the AP. Apple has been severely silent on this
    issue as well. However, it was always my opinion that us PB
    user's are out of luck, now that the MBP is out. Our model is a
    phased out model, and it is no surprise (though wrong) that a
    manufacturer would neglect any redesigns, major repairs, or
    recalls on an 'old' product. Sidenote: how interesting that the
    MBP has a redesigned airport antenna?

    What surprises me is that Apple is putting all these efforts into
    iPods, minis, etc, while neglecting a critical core of their users,
    the power users. The idea of spending $2000 on a laptop these
    days is borderline crazy (talking about me as well) unless you
    have a specific reason to. One of these reasons is knowing you
    have superb support behind your product. (Any of you who pay
    $2K for a laptop just because you hate Bill Gates are acting like

    So here is Apple, on their latest product, neglecting their
    constituents. WTH. Who are you protecting? 10 years ago, I
    was a die hard Dell fan. Claimed they had the greatest
    computers available, superior service, and price reflecting value.
    Today, I gag at Dell, knowing I'll be talking to someone from
    India in tech support, my hardware is marginal, and my price
    was low because of economy of scale.

    If this trend I see in Apple continues, I'll be looking elsewhere yet
    again. Linux? Don't know. Hope I don't have to change. But I
    do know that a $2000 laptop deserves better.
    • Trend, or inevitability

      There isn't anything particularly new about this case: the
      MacBook Pro (2006) is a fine product, just as the iBook G3
      (2001-2002 generation) was a fine product, but a percentage of
      each had manufacturing flaws.

      In the iBook's case it was a chip on the logic board which
      became unseated after extended use, causing spurious crashes.

      In the MacBook Pro's case it is a misapplication of thermal paste,
      causing excessive heat build up in the underside of the
      aluminum case.

      Both problems occurred at the factory and can be put down to a
      flawed manufacturing process. Although these are not the only
      ones, these are the Apple laptop flaws that have affected me,
      and as far as I know the ones most directly comparable.

      Spaced 5 years apart, I don't think it indicates a trend.

      Regarding Apple's policy: they never publicly admit a flaw until
      the percentage affected is known and a remedy is available.
      However, when that remedy is finally implemented it is executed

      My iBook was repaired 2.5 years after its purchase (without
      having an extended warranty) with a logic board replacement
      and the recent MacBook Pro was replaced without incident.

      Given the size of the consumer electronics industry and the
      scale and speed with which new products come to market, there
      is always going to be a percentage of defects. It is not a trend, it
      is a fact of life.
      • I must disagree

        "they never publicly admit a flaw until the percentage affected is
        known and a remedy is available"

        I fail to see why this is in any way acceptable to a consumer. I
        am not concerned about Apple publicly admitting anything; I am
        concerned about getting proper support on a defective product.
        Whether my laptop is the only one broken or there are
        thousands makes no difference; a problem should be resolved.

        It is also unnecessary for Apple to admit a flaw only after they
        have a remedy available. How foolish! If you have a problem,
        keeping silence only results in angry customers. This is like
        having a samba problem with Tiger (there have been many) and
        not letting your users know it exists, simply because you don't
        yet have a fix available. Meanwhile, you have frustrated
        customers trying to get a defective product working, thinking
        they are the problem.

        Or better yet, a battery problem, that could cause the battery to
        explode. Let's just keep quiet UNTIL we have a fix. And even
        DENY there's a problem until you have a fix. Because you don't
        have the percentages yet. That's a good one! Let me guess, if
        the percentages are low, do nothing, right? Acceptable collateral

        So it is the very policy of Apple you defend that I have a problem
        with. Whether it be a trend or inevitable really doesn't matter. A
        fix should be implemented.

        How about this: what temperature should the processor reach as
        a maximum? How about a hardware test that exercises the
        processor/memory and monitors the temperature? Every heat
        sink design has a maximum temperature constraint. Those that
        fail the test get repaired. This is simple, can be released in a
        timely manner, and will satisfy most users.

        Unless, of course, they know the results will be too expensive
        for them.
        • I agree

          I sound like he was in some way tring to defend Apple. If there is an issue then it should be corrected. Think of it in the same way if there was a toy that was known to contain a toxic chemical or was known to start a fire would and your kid had one. Would you:
          [A] Be cool that the company waited unil there were 30 case. Or

          [B] The corrected or pulled the product when the first issue came up.

          And no I'm not say that the laptop would kill you or anything like that.

          If it were MS there would be 100+ post flaming them. Don't defend or make an excuse for any company when they are doing wrong.
          • Sorry new keyboard.

            First sentence should've been:It sounds like he was in some way trying to defend Apple.
