I wonder how thermal management would work on a 3d cpu. You'd need copper filaments to wick away heat from the center of the cube I imagine.

- jbay808 6y agoDiamond, maybe! At least 8 times the thermal conductivity of copper. Although they might already be using it.
- Robotbeat 6y agoAnnealed pyrolytic graphite would be cheaper. 1700W/(mK) (In-plane) versus copper’s 400W/(mK) and is a quarter the density.
- Robotbeat 6y agoSome sort of fluid transfer would have much higher heat flux than copper (or even diamond). Maybe throw in a phase change, like micro heat pipes.
