Air heat sinks
An air cooler is a component used to cool electronic devices, such as processors or graphics cards, using airflow.
It consists of a metal base (usually copper or aluminum) that absorbs heat from the component and can be assembled with heat pipes that transport it, or with a radiator made of metal fins that increase the dissipation surface and with a fan (or more) that blows air on the fins to facilitate the dispersion of heat into the environment.
It is a simple, economical and effective solution for keeping devices at safe operating temperatures.
