Arctic Liquid Freezer II 420 aRGB AIO cooler review

Today, we are reviewing a 420 mm variant of an AIO cooler from the Arctic, Liquid Freezer II 420 ARGB. We’ve already covered the A-RGB 360 mm version and 240 mm 2 years ago and the non-RGB 280 mm – 3 years ago. This time, it’s the biggest available version, and it will be checked on an AMD Ryzen 7900X and 13th-gen Intel i9 13900K (previously, it was i7 4790K and i9 9900K), so it’s an up-to-date setup. There are the following variants available: 240 mm, 280 mm, 360 mm, 420 mm (the one reviewed here). Each one is possible to get with the A-RGB lighting or without it. The Arctic Liquid Freezer II uses an All-in-One formula, with a radiator and pump that are coupled into a single loop and aided by fans (3 x 140 mm). Speaking of fans, they are PWM-controlled 140 mm P-series units with 200-1900 rpm and noise performance up to 0.3 Sone (but you should know that each manufacturer measures this differently). Thanks to their high static pressure and outstanding performance, they should provide a fast heat transfer. The airflow is 68.9 cfm|117.06m3/h, and the static pressure is 2.0 mmH2O. You can find here a 40 mm VRM fan controlled by PWM and with an rpm range of 1000 – 3000. It prevents overheating, especially when you overclock, and allows for continuous heavy load. Regarding the dimensions, the radiator sizes are 458 (L) x 138 (W) x 38 (H) mm (L x W x H). The weight is 2019 g (Fan, Radiator, Pump, Tubes). The length of the tubes is 450 mm, with the outer 12.4 mm and inner 6.0 mm diameters. The Liquid Freezer II 420 aRGB has integrated cable management within fully sleeved tubes for a clean look in your PC’s case.

The Arctic Liquid Freezer II 420 ARGB is compatible with the following CPU sockets:

  • AMD – AM5, AM4
  • Intel – 1700, 1200, 115X, 2011-3*, 2066* *Square ILM

As for the lighting effects, the major brands’ software is supported. The lighting can be adjusted via a 5 V ARGB header on the motherboard to sync it all up.

We want to underline that we’re using the i9 13900K Raptor Lake processor to check the cooler and AMD Ryzen 9 7900X (previously, there were Intel Core i9 12900K and the Ryzen 7 3700X in the systems). Important -> A selection of motherboards interferes with the cooler. You can find the list of motherboards that have been confirmed to have this problem – here.

Arctic Liquid Freezer II 420 ARGB is sold at 148.99 EUR; the non-RGB is for 141.99 EUR. The warranty period is six years, so that can be a selling point, as the standard is two years (and only some other manufacturers offer five or six). So, let’s head to the specs/feature page, shall we?
