ARCTIC Liquid Freezer II 420 AIO CPU Water Cooler Review

The Liquid Freezer II line of AIO by ARCTIC currently includes 120/240/280/360/420mm models (the 240 variant is now also available with RGB and A-RGB fans) all of which feature 38mm thick aluminum radiators (quite a jump compared to the 27mm thick ones used with most AIO models out there currently). The 420 model in particular is a tri-fan model that uses three 140mm Arctic P4 PWM fans (1700RPM/72.8CFM/2.4mmH2O/22.5dBA), 450mm long braided EPDM (ethylene propylene diene monomer) tubes and a PWM pump/waterblock combo (2000RPM/copper plate) which is also equipped with a top 3000RPM VRM fan (according to Artic this helps cool the VRMs of your motherboard). Two things which are certainly worth pointing out is that the entire AIO is powered by a 4pin PWM motherboard connector (5.3W consumption for the entire AIO) and is covered by a very generous 6-year limited warranty.
