An efficient heat transfer technique for cooling microchips is developed using dynamic nanofin heat sinks. CrO2 nanoparticles are magnetically chained and docked onto hot spots, establishing high aspect ratio and flexible nanofins to facilitate the heat exchange between those spots and the liquid coolant. The system enhances the heat transfer and can offer a practical cooling solution for future electronics.
