How a motherboard works

Fans
Speeds , temperatures, density, faster chipset designs and component count have driven the need for circuit cooling via miniature electric fans. These fans mount inside the actual computer case. Heat sinks act like a car radiator , providing additional surface area to help cool a component.

Replaceable fan/heat-sink assemblies are often used to help dissipate the considerable amount of heat on modern processor chips. The assembly conducts heat away from the chip by convection, using a layer of thermal grease between the two mating metal surfaces. Fans often have a third wire used for monitoring the speed of the fan.
