CORSAIR announced the launch of its second-generation cooling hardware: NAUTILUS II all-in-one liquid CPU coolers and updated RS II and RS II ARGB fans. These components connect directly to the motherboard for simple fan management without external controllers, offering affordable and effective cooling with straightforward installation and maintenance.

NAUTILUS II RS LCD

The Nautilus II RS LCD succeeds the first-generation model 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 240mm or 360mm radiators, it combines powerful cooling with extensive display customization.

The standout feature is an upgraded LCD, expanding from a circular 2.1″ IPS display to a rectangular 3.5″ IPS LCD with 480×640 resolution at 60Hz. The screen simultaneously displays system metrics, animated GIFs, and iCUE Widgets at up to 60 FPS. The display connects via DisplayPort and functions 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. 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 Coolers

The NAUTILUS II Series replaces the NAUTILUS RS with an upgraded FlowDrive 2S pump, thinner AMD-optimized cold plate, and second-generation RS II fans in a Unified Frame design. The NAUTILUS II RS is available in black only, while the NAUTILUS II RS ARGB offers both black and white options. Both AIOs come in 240mm or 360mm radiator sizes.

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 with CORSAIR AirGuide technology focusing airflow. Magnetic Dome Bearings support 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, providing 24 individually customizable LEDs on 240mm models and 32 on 360mm models. Compatible motherboard software controls fan speeds and lighting without requiring an external controller.

RS II & RS II ARGB PWM Fans

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.

4 / 4 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

iCUE LINK Integration

NAUTILUS II AIOs and RS II fans integrate 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 CORSAIR iCUE software. The iCUE LINK System Hub docks directly to the COMMANDER DUO, providing unified control of PWM and iCUE LINK devices.
