The coolest heatsink... is the new Macbook Unibody

The entire piece is made of Aluminium, and my guess is that the “unibody” is sitting flat against both the NVIDIA chip and teh Intel processor - both of which emit a great deal of heat… All that heat will go through the unibody and away from the bottom of the macbook

And kudos to Apple for making CNC machined parts sexy…. and getting people to pay dearly for something that used to come for free… :-)
