Brief of a liquid cooling system

Water cooling, also called liquid cooling, is a method used to lower the temperature of computer processor units (CPUs), and sometimes graphics processor units (GPUs). This process uses water rather than air as the cooling medium because water can conduct heat about 30 times faster than air. Additionally, a water cooling system allows computer components to run at higher speeds while reducing system noise.

All electronics generate heat during operation. As computer components get faster and smaller, the amount of heat generated increases and it is more concentrated in smaller areas. Traditionally, the heat was removed from the components using air cooling, with heat sinks, heat pipes and fans to cool the system. However, some computer systems generate more heat than traditional air cooling can dissipate. This is common in overclocked, multiple GPU or high-density systems. For these high-performance systems, water cooling can remove heat faster and more efficiently allowing these systems to run faster, cooler and quieter.

In water cooled systems a liquid, usually water, is pumped through pipes. The liquid takes the heat from the components and dissipates it in a radiator. It operates on the same principal as the engine cooling system in a car where coolant is pumped through the engine and to the radiator.

Water cooling is most common in personal computers and computers designed for video games because it allows for overclocking the CPU and GPU while keeping the components cool. This can increase the lifespan of the components and it also allows for extremely small systems to be built with high-power components.
