what's the good in replacing thermal paste on your rev A MacBook Pro?

We already mentioned a few times before how Apple , if mean for a lot of things, was generous with thermal paste in his notebooks. In this case, if more certainly is better than less, too much paste can also result as an issue in cooling components. Julian had that problem:

I own a 2ghz MacBook Pro 2ghz rev A and it's a real oven: one can't keep it on his knees without burning himself and the keyboard gets hotter than Hell.
Since a few weeks, I noticed graphic bugs and the computer was freezing because the fans wouldn't speed up when needed. SMCFanControl helped me solved a part of this problem but here's the guilty one:

After a whole week-end following this guide for MBP's disassembling, I applied a small amount of Artic Silver themal paste on the three chips.
Since then, It runs 25 degrees C cooler on normal tasks such as surfing the web (25 vs 50), but no changes on hard tasks (88 degrees C for Cinebench).
What's better is that the heat conduction is great now and the fan reacts immediatly when needed. The computer freezes no more (on lightroom or ableton live for example) even if it is noisier than before...

Apple reviewed that issue and the notebooks now gets the right quantity of thermal paste.
