Thermal - Heat SinksHeat sinks are devices that are used to dissipate heat from electronic components, such as CPUs and GPUs, to help keep them within safe operating temperatures. They are typically made of metal and have a large surface area with many small fins or protrusions, which increases the amount of air that can come into contact with the heat sink and be cooled by convection. Heat sinks are often used in conjunction with fans, which help to further increase the flow of air over the heat sink and enhance its cooling capabilities.
