NAUTILUS II RS LCD – More Flow, More Show

The Nautilus II RS LCD succeeds the first-generation Nautilus RS LCD with a 67% larger 3.5″ display, an upgraded FlowDrive 2S pump, a thinner AMD-optimized cold plate, and new RS II fans. Available in black or white with a 240mm or 360mm radiator, it combines powerful cooling with extensive display customization.

The standout feature is the new LCD, which has been upgraded from a circular 2.1″ IPS LCD to a rectangular 3.5″ IPS LCD with a resolution of 480×640 at 60Hz. The screen can simultaneously show system metrics, animated GIFs, and iCUE Widgets at up to 60 FPS. The display connects via DisplayPort and can be used as a secondary display in Windows.

The second-generation FlowDrive 2S pump provides powerful liquid circulation, while the thinner cold plate reduces thermal resistance for improved heat transfer on the latest CPUs. RS II fans deliver concentrated airflow and excellent static pressure using CORSAIR AirGuide technology, supported by Magnetic Dome Bearings for quiet operation and enhanced longevity. Their Unified Frame design simplifies installation and cabling, while direct motherboard connectivity and Zero RPM Mode provide convenient control and quieter operation at low loads. 

Nautilus II RS / RS ARGB Liquid CPU Cooler – Truly Awesome AIOs

NAUTILUS II Series Liquid CPU Coolers replace the NAUTILUS RS with an upgraded Flowdrive 2S pump, a thinner AMD-optimized cold plate, and second-generation RS II fans in a Unified Frame design. The NAUTILUS II RS is only available in black, while the NAUTILUS II RS ARGB is offered in both black or white. Both AIOs are available in either 240mm or 360mm radiator sizes to satisfy the cooling needs of a wide variety of PC builders.

The NAUTILUS II RS complements high-performance blackout builds, while the NAUTILUS II RS ARGB adds vivid and customizable RGB lighting. Their Unified Frame fans reduce vibration and deliver consistent static pressure, while CORSAIR AirGuide technology focuses airflow. The Magnetic Dome Bearing in each fan supports quiet operation and long-lasting durability, and direct motherboard connectivity simplifies setup and maintenance.

Each RS II ARGB fan contains eight RGB LEDs, complemented by eight LEDs in the pump cap. This provides 24 individually customizable LEDs on the 240mm model and 32 on the 360mm model. Compatible motherboard software controls fan speeds and lighting without requiring an external controller. 

Together, the upgraded pump, cold plate, and fans deliver excellent cooling performance and refined acoustics in a streamlined design that is easy to install and maintain. 

RS II & RS II ARGB PWM Fans – COOL & QUIET

Second-generation RS II and RS II ARGB PWM fans deliver improved acoustics without compromising cooling performance. Redesigned CORSAIR AirGuide stator vanes reduce noise while focusing high-volume airflow through dense radiators for excellent static pressure. Magnetic Dome Bearings provide quiet operation and enhanced longevity.

Both series are available as 360mm Unified Frames that simplify cabling and mount using only four screws. Individual 120mm and 140mm fans are also available. Daisy-chain connectivity makes multiple fans easy to link and control as a group using compatible motherboard software.

RS II fans come in black, while RS II ARGB models are offered in black or white and include eight individually customizable RGB LEDs per fan.

READY FOR iCUE LINK INTEGRATION

NAUTILUS II AIOs and RS II fans can be easily integrated with iCUE LINK enabled fans using the COMMANDER DUO Lighting and Fan Controller (sold separately). Its dual PWM, ARGB, and iCUE LINK channels enable synchronized control through powerful CORSAIR iCUE software. The iCUE LINK System Hub docks directly to the COMMANDER DUO, providing unified control of PWM and iCUE LINK devices. 

Powerful and Quiet No-Hassle Cooling

NAUTILUS II AIO liquid CPU coolers and RS II PWM fans deliver quiet, effective cooling with straightforward installation and maintenance at an accessible price. With different colors, sizes, and configurations, these products make it easy to find the right cooling solution for your current or future build.
