Overview
- The Corsair NAUTILUS II 240 RS is a 240mm all-in-one liquid CPU cooler designed to deliver powerful, quiet cooling for modern processors. Built around a FlowDrive 2S pump and redesigned copper cold plate, it moves heat away from the CPU efficiently whilst maintaining minimal noise levels (36 dBA), making it suitable for both demanding workloads and noise-sensitive environments.
This cooler supports the latest socket standards: Intel LGA 1851, LGA 1700 and AMD AM5, AM4. The RS II Unified Frame fans feature precise PWM control (420–2100 RPM) and a Zero RPM mode that stops the fans during light loads, reducing noise and power consumption. Installation is straightforward thanks to pre-applied XTM60 thermal paste and simple daisy-chained PWM connections.
With a 12-month warranty and five-year extended coverage, the NAUTILUS II 240 RS combines reliability with practical cooling performance for gaming, content creation, and professional workloads.
