Heat sinks
The heat sink transfers heat away form the processor as the processor is unable to dissipate sufficient
heat to moderate this temperature. The heat sink is designed to maximize its surface area in contact with
the cooling medium surrounding it, such as the air. Thermal grease improve the heat sink's performance
by filling air gaps between the heat sink and the heat spreader on the processor.
