Corsair Nautilus 240 RS ARGB CPU Liquid Cooler (Black)

The Corsair Nautilus 240 RS ARGB is a 240mm all-in-one liquid CPU cooler designed for builders who want efficient thermal performance without the complexity of additional controllers or software. The cooler connects directly to a standard 4-pin PWM fan header on the motherboard, and the two included RS120 ARGB fans can be daisy-chained together so only a single header is needed — keeping cable management clean and straightforward. At the heart of the cooling loop is a pump rated at a whisper-quiet 20 dBA. The pump circulates coolant at a high flow rate through an aluminum radiator measuring 275 mm × 125 mm × 125 mm, which is cooled by two 120 mm RS120 ARGB fans. Those fans are tuned for a balance of high airflow and high static pressure, aided by Corsair AirGuide technology and Magnetic Dome bearing construction that helps reduce operational noise. PWM control allows fan speeds to reach up to 2,100 RPM under load, while Zero RPM mode lets the fans stop entirely during light workloads for near-silent operation. Maximum noise output at full fan speed is rated at 34 dBA. The cold plate is machined from copper for efficient heat transfer and features a slightly convex profile designed to improve contact with the integrated heat spreader found on modern CPUs. Thermal paste comes pre-applied in an optimized pattern to simplify and speed up installation. Socket compatibility covers Intel LGA 1851, LGA 1700, and AMD AM5 and AM4, making the Nautilus 240 RS ARGB a suitable choice for systems built around the latest Intel Core Ultra and AMD Ryzen processors. ARGB lighting on the fans can be controlled via the motherboard's ARGB header without any separate Corsair controller required.
