THE LIQUID FREEZER II 420

The Liquid Freezer II 420 may not look a lot different compared to other AIO's but its size and pump do stand out.

Measuring around 65mm in thickness with the fans installed the Liquid Freezer II 420 may not fit in towers even with 420mm room for radiators.

With an FPI (fins per inch) count of 15 the radiator is a good match for the bundled fans (higher RPM and static pressure fans however would clearly produce better cooling efficiency from a higher FPI radiator).

The fluid-dynamic bearing fans used with the Liquid Freezer II 420 are somewhat basic models that can reach speeds of up to 1700RPM and produce airflow levels of up to 72.8CFM with static air pressure of up to 2.4mmH2O at just 22.5dBA of noise.

Another thing that stands out with the Liquid Freezer II 420 is its EPDM (ethylene propylene diene monomer) coated tubes which ARCTIC has also used to route all 3 cables coming from its fans.

Even though the tubes are not rotatable from the pump/waterblock side their length should be more than enough to make installation easier.

As for the pump itself the 3000RPM diagonal fan on top is certainly something we don't see at all with AIO models (whether or not it works i will have to see later on).

ARCTIC has equipped the Liquid Freezer II 420 with a rather small copper coldplate which means that this AIO is not "ideal" for all CPUs out there.
