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. Jon:

    Interesting question. Perhaps Apple will be able to utilize the heat energy produced by the chips to also power the CPU. You know, like cold fusion, so battery life can be extended for weeks and weeks. What we need is a little civil disobedience and violate the laws of thermodynamics.

  2. Oh, and notwithstanding some pooh-poohs from others about hot chips aren’t bad, they’re wrong.

    If an engineer added a heatsink, it was done to keep something from overheating (most likely the chip). There is a logarithmic relationship between chip life and temperature. An over-capcity heatsink costs more money and takes up more space (a serious constraint in a laptop computer) so it’s not like there is excess heatsink capacity; engineers almost NEVER get excess heatsink capacity. If the heat isn’t getting into the heatsink at the “advertised” rate (under ideal conditions with the proper application of heatsink grease), then something’s getting too hot and that’s not good.

  3. Jon: See Greg’s post – hot laptop case = poor thermal dissipation.

    MacBook Pro owners – go get some Arctic Silver thermal paste, apply thin transparent layer between heat sync and CPU. Then see temperature drop 10-20 degrees as a minimum.

  4. If this was happening to Dell laptops MDN would be jumping all over them for their crappy laptop heaters because Apple has a great vertical business design model that gives them superior design, engineering and control. And they would complain about the shoddy work and components in the Dell.
    But Apple has defective products and its a learning experience for us all.

    I believe if anyone attempts this procedure their warranty is voided on their Apple heater….laptop.

    Now you know what´s delaying the next iBooks – they are too damn hot!

  5. anyone visit the Apple support forums lately? They’re beginning to look like a Dell forum. There some real quality conrol issues mentioned.

    Also, it appears from reading the comments that Apple is deleted users who post negative comments about problems they are experiencing with MacBooks. Buyer Beware.

  6. I’ve had several aluminum PowerBooks, and my new 1.83Ghz MacBook Pro runs cooler than any PowerBook I’ve ever used. I’ve even played Quake 4 on it for a while, and the fans stayed really quiet.

    As far as I can tell, the MacBook Pro is the coolest and quietest professional Mac laptop yet.

    The 12″ PowerBook, on the other hand, is another story. Run a 3D game on it for 20 minutes and it will be sizzling hot with its fans screaming like banshees. Sucks big time.
