Evolved from folded fin Heatsinks, offering even higher fin density with improved thermal conductivity since the fins are literally carved out of the Heatsink base. Specially designed blades cut very fine and thin fins into the raw metal block at an angle, which are then folded up and aligned. Since both fins and base are shaped out of a single piece of metal, skived fin Heatsinks provide the best possible thermal conductivity between fins and base.
