A heatsink is a piece of hardware that helps to dissipate heat away from sensitive components on a computer. Heatsinks are often used in conjunction with fans to create an airflow that helps to keep components cool.
The most commonly used type of heatsink is made from aluminum, which is an excellent heat conductor. Heatsinks come in a variety of shapes and sizes, and are custom-designed to fit the specific component that they will be cooling.
Heatsinks are an essential part of any computer, and play a vital role in keeping components cool and functioning properly.
