Cool Performance, Zero Compromise

The Corsair NAUTILUS 240 RS ARGB Liquid CPU Cooler is built for anyone pushing their processor hard, whether you're rendering, gaming, or running demanding workloads day after day. It pairs a 240mm aluminium radiator with a copper cold plate to pull heat away from your CPU efficiently, giving your system the thermal headroom it needs to run at its best. Straightforward installation means it plugs directly into your motherboard, with no additional controllers cluttering your build.

Tired of Coolers That Trade Quiet for Performance?

Many liquid coolers force you to choose between low noise and strong cooling. The NAUTILUS 240 RS ARGB avoids that trade-off with its RS120 ARGB fans, delivering airflow up to 72.8 CFM and static pressure up to 4.15 mm-H2O when your CPU is under load, while dropping to as low as 10 dBA — and into a Zero RPM mode — when demand eases off. Precise PWM control manages this balance automatically, so you get cooling when you need it and near-silence when you don't.

Built to Fit Your Platform

Upgrading or building fresh, compatibility shouldn't be a guessing game. The NAUTILUS 240 RS ARGB supports Intel LGA 1851 and LGA 1700 sockets alongside AMD AM5 and AM4 platforms, making it a dependable choice across current and recent-generation systems. A 400mm tube length gives you the flexibility to route the radiator where it fits best in your case, whether that's up top or at the front.

Lighting That Matches Your Build

Beyond the numbers, the NAUTILUS 240 RS ARGB brings dynamic ARGB lighting to your setup, letting you tie the cooler's look into the rest of your build's aesthetic. It's cooling that performs quietly under load and looks the part while doing it.
