14 Best Closed Loop Liquid Cooler (2022 Updated)

A closed loop liquid cooler is a type of cooling system that uses a closed loop of water to transfer heat away from a heat source. The closed loop liquid cooler typically consists of a water pump, a water block (which contains the heat source), a radiator, and a fan.

The water pump circulates the water through the closed loop, and the water block transfers the heat from the heat source to the water. The radiator then transfers the heat from the water to the air, and the fan cools the air.

Conclusion

A closed loop liquid cooler, also known as a CPU water cooler, is a cooling system that circulated water or other liquid coolant to remove heat from a computer processor or other heat-generating component.

The water is then cooled by a radiator or other cooling device before being recirculated back to the processor.

Closed loop liquid coolers are more effective than air coolers at removing heat from processors, and they also tend to be quieter. However, they are more expensive and require more maintenance than air coolers.
