The computer CPU heatsink draws heat away from the computer's central processing unit (CPU). The computer CPU heatsink has a thermal conductor that carries heat away from the CPU into fins that provide a large surface area for the heat to dissipate throughout the rest of the computer, thus cooling both the heat sink and processor. The computer CPU heatsinks are made of aluminum, which serves as the thermal conductor that carries heat away from the CPU. SJHM provides a wide range of extruded aluminum computer CPU heatsinks and can also custom laptop heatsinks.
