MacBook Pro temps drop with thermal paste makeovers

“Any PC enthusiast knows that thermal paste is something to be applied in precise amounts. Maybe Apple could take a lesson from all of us out there who have tacked a cooler onto a CPU. Apparently, the recent rash of toasty MacBooks can be attributed to excessive amounts of silicon thermal paste applied between chips and heat sinks. A number of MacBook users have, in heated desperation, resorted to cracking open their MacBooks only to find minuscule amounts of thermal silicon between the chip and sink, but massive amounts of silicon paste spilling out around the edges. Now, if the silicon thermal paste had been applied properly all these MacBooks wouldn’t be cooking themselves to death,” J. Micah Grunert reports for Neoseeker.

“Some MacBook users had cried that their computer was running at just over 50 Degrees Celsius. But once a better thermal paste replaced the silicon, temperatures dropped to roughly human body temperatures, some 35 to 39 Degrees Celsius,” Grunert reports.

  1. Ummmm… doesn’t a cooler case mean toastier chips??? I mean, if the case was so hot, it means the thermal paste was doing it’s job and transferring heat from the chips to the metal case. So, now, if the case is cooler, then is the heat trapped on the chips? Maybe these guys should check their chip temps before they get too excited. Or maybe I’m missing something. First post?

  2. I’m glad MDN posted this article, apparantly quality control is dropping considerably at Quanta Computer, Apple’s (and just about everyone else’s) laptop computer maker.

    Apple is having a hard time demonstrating their hardware is better when they are made as cheaply as cheap Dell PC’s.

    Get cracking Apple, your reputation for quality is going downhill in a hurry.

    1: Mac OS X security

    2: Whine, speaker and heat problems on MacBook Pro’s.

    3: Aperture

    Perhaps the Apple folks are getting pushed to hard lately?

  3. The first two posters are wrong.

    If there is too much thermal paste, the paste will act as a insulator, thereby preventing heat transfer to the copper heatsink, creating the high default temperatures on MBPs.

    Apple should have used a thin film of thermal paste — less than 1mm thick — on the MBP chips. This is the proper way, and allows unencumbered heat transfer from chip to heat sink, resulting in cooler temperatures.
