Liquid cooling uses a liquid, such as water, or a refrigerant, rather than air, to cool the data canter. This allows the cooling solution to be brought closer to the heat source, thus requiring less, if any, fan power. Liquid cooling can solve the high-density, server-cooling problem, because liquid (conductive cooling) conducts more than 3,000 times as much heat as air and requires less energy to do so, allowing increased data center densities. Newer piping technology means the probability of leaks is extremely low.
