Liquid cooling systems

The principle of cooling liquid applied to the PC is similar to the operation of the radiator on cars. According to the same principle, to cool a CPU liquid is flowing on a stand or CPU cooler known as "Waterblock", in which a liquid remove heat from CPU.(liquid can be water, colored fluid, coolant, combined with an anti-algae).
This liquid is passed with a recirculation pump in a water circuit, which carries the heat from the inside to the outside of the case, then cooled using a radiator and a fan or a radiator large surface, which requires no fan and so it was totally silent.

Despite the superior characteristics of the water in heat transfer, many believe that the system of liquid cooling is dangerous, mainly due to the fact that the water appears to be also a perfect conductor of electricity.

Another factor to consider is maintenance. The air systems are simple and inexpensive to obtain and maintain than the systems to liquid, but more difficult to deploy and manage. The components for liquid systems are ultimately more expensive than air.
There is thus a clear risk factor associated with liquid cooling with computers but if you apply the necessary precautions, and follow strictly advice, guidance and instructions of an expert there is no danger, and the results that you can get really considerable. With all these negative characteristics, it seems that it is not easy to sell such systems, in reality the thermal benefits of liquid cooling are so attractive that makes you forget additional costs and difficulties.

Benefits: The thermal conductivity of water is 25 times greater than that of air. The ability of water to absorb heat and place it outside the case is a great benefit as is the fact that the liquid cooling with the proper fans is very quiet.

Disadvantages: It is not certain that it is always the best choice: difficult maintenance, risk of water on the motherboard that can destroy Hardware, high costs.
