What component is used to cool the CPU?

The heat sink and fan assembly plays a crucial role in cooling the CPU. The CPU generates significant heat during operation, and if this heat is not dissipated efficiently, it could lead to thermal throttling or even damage to the processor. The heat sink is typically made of metal, which conducts heat away from the CPU, while the fan helps to enhance air circulation, further dissipating heat by blowing air over the heat sink.

In combination, these components work together to maintain optimal operating temperatures for the CPU, ensuring stability and performance. While other cooling methods, such as liquid cooling systems, are effective and used in specific situations, the heat sink and fan assembly is the most common and widely used solution in many computer systems.
