This is a 360 mm all-in-one cooler for people with a high-power AMD or Intel chip who want maximum cooling headroom. It suits builders who are happy to set a fan curve and fit a long radiator. It is a weaker choice for anyone who wants a quiet build with little setup.

6.9/10verdict: good, not the best

The AK620 DIGITAL is for builders who want a large dual-tower air cooler for a current Intel or AMD desktop. It suits anyone who values strong cooling and a visible temperature or load readout in the case. It is best for people willing to set a custom fan curve to manage noise.

Strengths and weaknesses

ARCTIC Liquid Freezer III Pro 360

+ Lower temperatures than two 360/420 mm rivals in Club386's tests
+ MX-6 paste is pre-applied and the warranty runs six years
+ Separate VRM fan covers the socket area
− TechPowerUp calls the fans excessively loud above 50% PWM
− Intel mounting is a hassle and no manual was included
− An owner returned one over pump noise

Skip it if:

Buyers who want a quiet system and will not tune fan speeds
Intel builders who want a simple, well-documented mounting process
Anyone whose case cannot take a 398 mm-long 360 mm radiator
