Corsair NAUTILUS 360 RS

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.

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

Corsair NAUTILUS 360 RS

  • + Reported peak of 81°C on an i9-14900K
  • + Quiet at idle and light load, owners say
  • + Five-year warranty and pre-applied XTM60 paste
  • − Installation can be difficult in compact cases
  • − Fan noise rises under sustained heavy load
  • − Higher temperatures reported in small or poorly ventilated cases

Skip it if:

  • Builders with compact cases that struggle to take a 360mm radiator

DeepCool AK400

  • + Strong cooling for the money, per owners
  • + Supports LGA1851, LGA1700, AM5 and AM4
