Cooling Performance Without the Noise

For PC builders who demand serious thermal performance without the roar of a wind tunnel, the Corsair NAUTILUS 240 RS Liquid CPU Cooler delivers efficient, low-noise cooling that helps your CPU reach its full potential. Built around a 240mm aluminium radiator and a copper cold plate, it's designed to handle sustained workloads and long gaming sessions alike, keeping temperatures in check while staying refreshingly quiet.

RS120 Fans: Built for Airflow and Silence

Tired of coolers that trade quiet running for cooling power? The NAUTILUS 240 RS pairs its radiator with RS120 fans engineered to deliver high airflow (13.3 - 72.8 CFM) and strong static pressure (0.2 – 4.15 mm-H2O), all while keeping noise to a minimum. Running at up to 2100 RPM, these fans push air efficiently through the radiator fins without turning your rig into a distraction, so you can focus on the work or the game in front of you.

Precise Control, Zero Fuss

PWM fan speed control puts you in charge of the balance between cooling and quiet, automatically adjusting fan speed to match your system's needs. When things ease off, Zero RPM mode lets the fans stop spinning altogether for genuinely silent operation at idle and under light loads. Better still, the NAUTILUS 240 RS plugs directly into your motherboard, with no additional controllers or software required to get it running.

Ready for Your Platform

Whether you're building on the latest Intel or AMD platform, the NAUTILUS 240 RS is ready to fit. It supports Intel LGA 1851 and LGA 1700 sockets alongside AMD AM5 and AM4, making it a dependable choice for current and recent-generation builds. With a 400mm tube length for flexible routing and a 60-month warranty backing it, this is a cooler built to stay part of your system for years to come.
