INTRODUCTION

   Bigger has always meant better, at least in regards to radiators and in turn cooling efficiency. Yes, a larger sized radiator (length, width and thickness) is in many cases not exactly practical but if you want the best possible cooling results this is the easiest and fastest way to achieve them (right after the type of material used, copper or aluminum, followed by the number of fans and the number of radiator channels and fins). Now as many of you are probably already aware in the PC industry the very 1st AIO models which debuted well over a decade ago featured 120mm radiators with room for a single fan or even two fans in push & pull configuration. With quad-core CPUs back then these were actually somewhat sufficient but as AMD and Intel added more cores into their CPUs AIO manufacturers slowly introduced larger (140/240/280/360mm) and improved models to keep up with the rather significant increase in temperatures. Today the largest AIO models feature 420mm radiators and one of them is the latest Liquid Freezer II A-RGB by ARCTIC which is also what today's review is all about.

   ARCTIC, a leading manufacturer of low-noise PC coolers and components, initiated and continues to shape the trend towards quiet cooling systems. In addition to an extensive range of CPU/GPU coolers and fans, ARCTIC produces high-quality monitor arms and wall brackets as well as practical tech equipment. The company, headed by founder Magnus Huber, has offices in Germany, Hong Kong and the USA. It has won over PC enthusiasts in more than 45 countries with innovative and user-friendly products that are high quality and sold at fair prices. For almost 20 years, ARCTIC has stood for comfortable computing, stellar service and personal support.

   The Liquid Freezer II 420 A-RGB model is the last one released by ARCTIC (the liquid freezer II A-RGB line includes 240/280/360/420mm models) and as expected it features an 38mm thick aluminum radiator (as with all the other members of that line) and three 140mm P14 fans (PWM fluid-dynamic bearing with A-RGB lighting) complete with integrated cable management (routing). Of course, it also comes ready with 450mm long braided EPDM (ethylene propylene diene monomer) tubes and an PWM pump/waterblock combo (2000RPM/copper plate) equipped with a top 3000RPM VRM 40mm fan (which indeed helps with VRM temperatures). Typically, the Liquid Freezer II 420 A-RGB is also an 4pin powered model (6.78W consumption for the entire AIO) and as for warranty just like with all the other members of that line ARCTIC covers it with a very generous 6-year limited one.
