Corsair Nautilus RS ARGB AIO Liquid CPU Cooler — Black | 240mm / 360mm | Intel LGA1851/1700 / AMD AM5/AM4

The Corsair Nautilus RS ARGB is built for gamers, content creators, and enthusiast PC builders on Intel or AMD platforms who want effective, low-noise AIO liquid cooling with ARGB aesthetics and completely controller-free plug-and-play simplicity. The 240mm variant suits mid-range CPU builds and cases with limited radiator space, while the 360mm variant provides higher thermal headroom for flagship high-TDP CPUs and sustained demanding workloads. Both variants are ideal for clean, minimal cable builds that connect directly to the motherboard without proprietary hubs, adapters, or additional software.

The Nautilus RS ARGB features CORSAIR's slightly convex cold plate design with factory-applied thermal paste in an optimised spread pattern, ensuring maximum contact surface area with the CPU integrated heat spreader (IHS) for superior heat transfer from first installation. Dual or triple RS120 ARGB fans — for the 240mm and 360mm variants respectively — feature CORSAIR AirGuide technology to direct airflow precisely through the aluminium radiator fins, while Magnetic Dome bearings deliver near-silent operation and long-term reliability across the 0–2100 RPM range; each fan is equipped with eight addressable RGB LEDs and supports Zero RPM mode for completely fanless operation at low loads. All fans daisy-chain together via 4-pin PWM headers, connecting to a single motherboard PWM fan header for a clean, simple build with precise PWM speed control. The efficient low-noise pump circulates coolant at a whisper-quiet 20 dBA with a high flow rate through 400mm low-permeation rubber tubing to keep coolant fresh over its lifetime. Eight addressable RGB LEDs on the pump head light up alongside the fan LEDs for a cohesive ARGB display controllable via motherboard RGB software or optionally via a CORSAIR iCUE controller (sold separately). The 240mm radiator measures 275×120×27mm with two fans, while the 360mm radiator measures 396×120×27mm with three fans — both featuring standard 27mm thickness for broad case compatibility.
