The Arctic Liquid Freezer II 420 is a multi-compatible all-in-one water cooler. The Liquid Freezer II combines the efficient PWM pump of the Liquid Freezer II with fans optimized for static pressure. This results in a completely different aesthetic with extremely low noise levels and equally low temperatures. The water pump's humming has been reduced and its efficiency increased. Like the other components, it is also PWM-controlled. This results in significantly lower noise levels under low and normal loads, as well as much lower power consumption of 0.9 W at idle, 2.5 W under normal load, and a maximum of 5.3 W under full load for the entire AIO.

• 38mm thick radiators with high fin density
