How Does an AIO CPU Cooler Work?

An AIO CPU cooler operates on the principle of liquid cooling, where a mixture of water and a heat-conductive liquid, such as propylene glycol, is used to transfer heat away from the CPU. This liquid circulates through a closed loop system, consisting of a pump, tubing, and a radiator with fans.

The process begins with the pump, which is typically located on the CPU block. The pump draws the liquid from the CPU block and pushes it through the tubing, creating a continuous flow. As the liquid flows through the CPU block, it absorbs the heat generated by the processor.

Once the heated liquid reaches the radiator, it is dispersed across the radiator fins. The radiator is equipped with a series of channels and fins that increase its surface area, promoting efficient heat dissipation. Simultaneously, the fans attached to the radiator force air to flow over the fins, facilitating the transfer of heat from the liquid to the surrounding environment.

As the liquid cools down, it travels back to the CPU block through the tubing, ready to absorb more heat. This constant circulation of the liquid ensures a continuous cooling process, effectively dissipating the heat generated by the CPU.

The effectiveness of an AIO CPU cooler is influenced by various factors, including the size of the radiator, the number and speed of the fans, and the quality of the thermal paste applied between the CPU and the cooler. Larger radiators with more fans generally provide better cooling performance, as they can dissipate heat more efficiently.

Additionally, the pump plays a crucial role in maintaining the flow rate and ensuring that the liquid reaches the CPU block consistently. High-quality pumps with durable bearings and low noise levels are preferred for optimal performance.
