How Does a CPU Cooler Work?

CPU coolers are ideally designed to keep the system’s temperature within an optimal temperature to enhance the functionality of the processor to a great extent. Although, most of the advanced processors are now equipped with a temperature sensor to ensure that it does not overheat.

Despite that, there are some cases where the system might overheat; therefore, you need to incorporate a CPU cooler to move the heat away. A CPU cooler keeps the temperature low with a specialized design. It includes heat pipes generally made from copper, filled with liquid, which gets evaporated when heated. The vapors formed travel to the cooler and condense to release the trapped heat. Moreover, the cooling fins cover a large area to add on to the cooling effect.
