Rank #4 in Best AIO CPU Cooler 2026: 10 Ranked, and the Spec Numbers That Disagree
Corsair NAUTILUS 360 RS ARGB (Black)
Price and rating as shown on Amazon when we collected them. Both change.
The Corsair NAUTILUS 360 RS ARGB is the fourth entry in this guide to 360mm all-in-one liquid coolers. It pairs a 360mm radiator with three RS120 ARGB fans, a slightly convex cold plate that arrives with thermal paste already applied, and daisy-chained wiring that runs the fans from a single 4-pin PWM header plus one +5V ARGB header. The listing price is £79.99, and it carries a 4.6 rating from 1,181 ratings.
The number to look at here is the noise figure, because the listing gives two. The bullet points describe an "efficient, low-noise pump" generating a "whisper-quiet 20 dBA", while the specification field further down prints "Noise Level: 36 Decibels". That is the same cooler, on the same page, 16 dB apart — and the two fields do not even use the same unit. The wattage field is worth a second glance too: it reads "10 Watt-hours", which is a unit of energy rather than the power draw you would expect next to a 12-volt, 4-pin connector. The rating breakdown supplied with the listing adds up to 100, split 81 at five stars, 9 at four, 5 at three, 1 at two and 4 at one. Everything on this page comes from the Amazon listing as supplied, not from any testing of our own.

Verified purchase“Might be the best fans for heat and looks, did have a ticking noise but corsair support replaced it free of charge and now its really quiet.”
