Passive air-cooled heat sinks feature improved airside heat transfer performance. Integrate novel vapor chamber technology within a 3D thermal solution, with vapor flow spreading heat both laterally in the base and into planar appendage heat pipe blades. High-density fins are attached to the planar blades to enhance thermal performance. Reportedly feature thermal uniformity and low thermal resistance. Handle heat loads from 250W to 2,000W, depending on model. Built with copper (wall and wick) and aluminum (fins); the working fluid can be water or methanol. Customizable mounting features .
