What component helps push coolant around the liquid cooling system?

The component that pushes coolant around a liquid cooling system is the pump. In a liquid cooling configuration, the pump is essential because it circulates the coolant through the various components, which include the water block, radiator, and reservoir.

The water block absorbs heat from the CPU or GPU, transferring it to the coolant. Then, the pump ensures that the heated coolant is moved away from the component to the radiator where it can be cooled down before being cycled back to the water block. Without the pump, the coolant would not flow effectively, and the cooling system would be unable to regulate temperatures properly, potentially leading to overheating.

Other components, like the reservoir, store coolant and help maintain an adequate amount of fluid in the system, and the radiator dissipates heat from the coolant into the surrounding air. The water block is critical for absorbing heat but does not contribute to the movement of the coolant itself.
