[1] Some of the drawbacks include the risk entailed with the close proximity of liquid to electronics as well as its cost.
Liquid cooling systems are more expensive than fan sets, which require fewer components such as reservoir, pump, water blocks, hose, and radiator.
[1] Liquid cooling is also used to remove heat from large buildings by using chillers which transfer the coolant from the evaporator to air handling units, chilled beams and fan coil units inside the building, and to the cooling towers from the condenser if the condenser is liquid-cooled.
Generally, an LCG uses a series of coolant-filled tubes and a refrigeration unit and a pump to move the coolant throughout the system.
[5] Due to their portable and versatile nature, LCGs have been proposed as a solution to overheating in areas where a standard air conditioning system would not be feasible or where the cooling would need to be under protective gear.
