Air-cooling is a method of cooling a system or device that utilizes air as the cooling medium. It is an effective way to cool a system or device without the need for additional components such as a water pump or radiator. Air-cooling works by drawing in air from the outside environment and passing it over the components of the system or device. The air absorbs the heat generated by the components and carries it away, thus cooling the system or device. Air-cooling is an efficient and cost-effective way to cool a system or device, as it does not require additional components or energy to operate. It is also a great choice for those who are looking for a quieter cooling solution, as air-cooling does not produce any noise. Air-cooling is an ideal solution for those who are looking for a simple and reliable cooling solution.
