Cooling
Liquid cooling
Liquid cooling has many advantages, which derive from the much higher heat capacity per unit volume of water compared to air (by a factor of 3500 times higher). Liquid cooling implies higher densities, energy savings and the possibility to reuse the thermal energy that the water extracts from the IT equipment. Some additional advantages can be found in terms of lower noise levels, less vibrations and close control of electronics temperatures.
