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.

6.5/10verdict: good, not the best

The Nautilus 360 RS is for buyers with a case that takes a 360mm radiator and a CPU that runs hot under load. It suits Intel LGA 1851 and LGA 1700 or AMD AM5 and AM4 builds that want a ready-to-fit AIO with paste already applied. It is less suited to compact or poorly ventilated cases.

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
