ARCTIC Liquid Freezer III Pro 360

6.8/10verdict: good, not the best

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.

DeepCool AK400

7.1/10verdict: good, not the best

The DeepCool AK400 is for builders who want a low-cost air cooler for a mainstream Intel or AMD desktop CPU. It suits anyone who wants current socket support, including LGA1851 and AM5, without paying for a bigger tower or an AIO. It is a sensible pick for mid-range builds, and less so for chips that draw well above its 220 W rating.

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

DeepCool AK400

+ Strong cooling for the money, per owners
+ Supports LGA1851, LGA1700, AM5 and AM4
+ Easy installation reported by owners
− Reported 8% throttling on an 11900K in the FPU test
− 42 dBA at full 1850 RPM in KitGuru's figures
− Mounting kit and pre-applied paste draw criticism

Skip it if:

Buyers with a hot, high-power CPU that sits near or above 220 W under sustained load
Anyone with a compact case that can't take a 155 mm cooler
Buyers who want quiet full-speed operation without setting a fan curve
