The WaterChill Antarctica KT12A-L30 kit comes with an external 1200-liters-per-hour pump from Hydor, powered from the power grid. Water-cooling kits for enthusiasts don’t save on power, whereas inexpensive systems use tiny submersible pumps with a capacity of 30-200 liters per hour.
The powerful pump ensures a strong water flow under any conditions, even if there are many water-blocks and long tubes in the assembled system.
A small reservoir shares the same stand with the pump. It serves to fill and bleed the system rather than to increase the volume of the coolant.
The radiator is both glory and problem of this cooling kit. The excellent “Black Ice” design is supposed to accommodate two 120mm fans. This size and this cooling ensure a highest efficiency, but some system cases won’t accommodate this contraption without some modifications.
