There are interesting non-metallic materials already in large-scale production which serve as excellent heat sinks and pipes. As an example, pyrolytic graphite has a thermal conductivity several times greater than that of Cu: https://www.mouser.com/m_new/panasonic/panasonicthermalgraph...

Heat sinks and pipes don't matter all that much since you can simply increase the area to achieve higher conduction. The bottleneck is getting it from small chip hotspots to the heat spreader on top of the chip. So this would sit as a layer directly on top of the chip beneath the more conventional heat spreader.
