For those who have already gotten a new Mac Book Pro and have found the heat generated by the system a bit excessive, you may want to see this. A poster on the MacRumors forums Nikhsub took apart a week-old MacBook Pro after reading some news on the horrible application of the thermal paste on the units chips.
After opening the unit, he discovered that the GPU, CPU, and Northbridge were indeed overly slathered by thermal paste. For those who don't know the recommended amount, lets just say that a small pea-sized dab would be good enough for a processor chip. Check out the amount that was found on the unit that Nikhsub purchased. He also found the heat pipe cooler heatsinks covered with thermal paste (third image). This shouldn't have been lathered with the stuff in the first place! So after cleaning up everything that needed to be cleaned and reapplying a thin coat of thermal paste, the unit was found to be running a full 20 degrees lower then before the clean up. Here are a few pics of the board and heatsinks cleaned up. Nicksub may have done a cool job of cleaning his Mac Book Pro but if your system is running hot, you may want to have an Apple specialist open it up and check it out for you. |

I'm planning on buying a MacBook Pro(in 1-2 months), and this isn't very good news. :S

This has been blogged to death when the 1st MBP came out. Get some real news.

» Thermal paste not the reason
I've owned the 1st gen MBP and had the same heat issue with the overly enthusiastic application of thermal paste. I got that cleaned up by an Apple tech and re-applied to the normal amount (about 0.5mm layer on the die).
The result was little to no change in the heat underneath the Macbook Pro. Once you start doing anything processor intensive like playing games or using Parallels, the heat generated underneath goes up to a very uncomfortable level.
The over-application of thermal paste isn't the reason why MBP gets too hot. The reason is two things, one is the metal enclosure is supposed to act as part of the heat dissipation mechanism. And two, the cooling fan strategy used.
Apple has decided to try and keep the Macbook Pro as quiet as possible, and also by trading more heat, for less current draw to the fans. What inevitably results is you get a nice quiet machine with good battery life, but temperatures too unbearable to use on your lap while playing games.
You can get around this by using smcfancontrol or any other fan control app out there where you can manipulate the fan strategy used. You for instance can set the minimum rpm for the fan so it keeps the underside always cool, but sacrificing battery life and increased noise.

» Disappointing...
I really feel like apple should have taken care of this by now, but I'm still gonna get a mbp when the 17" LED LCD's hit.
