There we have it! Our first foray into the thermal solution of this beast! For the uninitiated, this is graphite. It is covered in black plastic, but it is an incredible thermal conductor.
Take note here...if you are ever to do work on these (or any smart phone today) take special care around this material. It is critical to the thermal stability of the device!
Did I mention is it flexible? Plus, 3X the thermal conductivity of Copper! Cool stuff.
