I've done a search, and I haven't found anything concerning the new unibody macbooks.

In the past, people were concerned with their macbook pros because they were overheating and it was speculated that poor application of thermal grease or paste was the culprit.

and ifixit.com shows it also being messy

but the unibody macbooks on ifixit seem pretty clean thermal paste

but their next picture shows that the thermal paste completely removed, so i don't know if they cleaned it up before taking a picture

Has anyone besides ifixit diassembled their unibody macbook to see what the thermal paste looks like?
 
Laptops shouldnt need much thermal paste, if any at all.

The new Unibody Macbooks and Macbook Pro's dont have the same overheating problems as the old ones.

:)
 
i'm thinking about getting one because i think the unibody model is so groundbreaking

it's so sturdy because of the unibody design (i had a 17" MBP in the past whose palmrest had a flex (it was side with the superdrive.

the nvidia chipset should provide optimal support for OpenCL when Snow Leopard hits the ground

but my biggest concern is with heat and noise. while i understand that you can have a cooler notebook when the fans are going at higher speeds to cool it down, I think there could be a happy medium.

anyways, i have found my answer.

disassembled by renowned "kodawarisan" it also shows a relatively clean thermal pasting job. While not as clean as your DIY job, it is well done for a mass production job. (i tried googling for the guy earlier, but i couldn't remember how to spell his name)
 
You know too much thermal paste is a bad thing. More than 0.5mm thick is way too much.

Contact between the two metal plates (CPU and Heatsink) is a much better way to transfer heat than Plate --> Thermal Paste --> Plate.

Actually thermal paste increases the transfer of heat between a device and the heat sink, unless all my engineering classes and experiences have been lying to me and yes when used its only supposed to be applied in a thin layer.

Thermal paste has a lower conductivity than metal, it's used to ensure a better contact between the two surfaces as they're obviously not 100% smooth.... maybe you fell asleep for all your engineering classes ;)
