Background

Integrated circuits are heavily used in computer components. It is known that the heat that causes the high temperature does not come from outside the computer, but inside the computer, or inside the integrated circuit. Most heat sinks absorb heat by contacting the surfaces of heat-generating components, and then transfer the heat to a remote location by various methods, such as air in a chassis, and then the chassis transfers the hot air to the outside of the chassis, thereby dissipating heat from the computer.
