One of the main components in the CPU is the CPU fan. It is the most economical and effective way to cool down the processor and protect it from overheating. The CPU fan is critically necessary to ventilate the heat generated from the components, and actively cools the processor by bringing in cooler air before the heat damages the computer components.
Cooling fans for the CPU are available in different sizes and is usually sold with an aluminum or copper heat sink fan. The CPU cooling fans are attached directly on top of the CPU, and works along with an aluminum heat sink fan to cool down the CPU and dispels any hot air from circulating around any circuitry boards, video cards, the motherboard, and other components that work with your computer, thereby ensuring that they are cool and operable.
