Why CPUs Need Heat Sinks?

Heat sinks are components that are responsible for transferring heat from a solid material to air or liquid medium. They increase the contact surface area to make heat transfer faster.

Modern computers have CPUs as their heart that processes all the data. Processors become hot very quickly but require cooling to function properly. This is what the heat sinks are for.

Computer heat sinks are attached to the processors to collect heat from them and transfer the collected heat to air or liquid media. Fans or thermal cooling solutions are attached to the heat sinks to take the heat away from them so they can provide necessary cooling to the processor.
