Is the heat sink solid metal?
I have a MacBook Pro that operates in extreme cold temperatures and it appears that the heat sink ruptured in the cold operating climate. We've never had this problem with our original MacBook Core Duo. The heat sink looks like it is a solid bar or metal to draw the heat away to the fan. Can anyone confirm this?
Esta é uma boa pergunta?

I've been into this machine but unless you cut open the heat sink I don't think I could tell what it's made of. Why do you think it ruptured, could you upload a picture. I've never heard of a heat sink rupturing.

I would think that you are looking at a solid piece of metal, It will carry heat better than something that would be hollow/honeycomb on the inside. As for the metal, I'd go out on a limb here and suggest an aluminium alloy. "Aluminium alloys 6061 and 6063 are the more commonly used aluminium alloys, with thermal conductivity values of 166 and 201 W/m•K, respectively" from Wikipedia.
