Corsair (Nasdaq: CRSR) announced second-generation cooling hardware: NAUTILUS II all-in-one liquid CPU coolers and updated RS II and RS II ARGB fans. These components deliver powerful, low-noise cooling with easy setup and management for simple plug-and-play operation on any modern PC. NAUTILUS II, RS II, and RS II ARGB devices connect directly to the motherboard for simple fan management without external fan controllers, offering affordable and effective cooling with easy setup and maintenance.

The launch includes a wide range of new hardware: NAUTILUS II RS LCD Liquid CPU Cooler (240/360, Black or White), NAUTILUS II RS Liquid CPU Cooler (240/360, Black), NAUTILUS II RS ARGB Liquid CPU Cooler (240/360, Black or White), RS II PWM Fans (RS120 II, RS140 II, RS360 II Unified Frame, Black), and RS II ARGB PWM Fans (RS120 II, RS140 II, RS360 II Unified Frame, Black or White).

The Nautilus II RS LCD succeeds the first-generation with a 67% larger 3.5" display, an upgraded Flow Drive 2S pump, a thinner AMD-optimized cold plate, and new RS II fans. The LCD is a 3.5" IPS at 480x640 and 60 Hz, showing metrics, GIFs, and iCUE Widgets. The Flow Drive 2S pump provides powerful liquid circulation, while the thinner cold plate reduces thermal resistance. RS II fans use Corsair Air Guide technology and Magnetic Dome Bearings for quiet operation and longevity. Their Unified Frame design simplifies installation and cabling, with direct motherboard connectivity and Zero RPM Mode.

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 only black, while the NAUTILUS II RS ARGB is black or white. Both AIOs come in 240 mm or 360 mm radiator sizes. Each RS II ARGB fan contains eight RGB LEDs, plus eight LEDs in the pump cap, providing 24 individually customizable LEDs on the 240 mm model and 32 on the 360 mm model. Compatible motherboard software controls fan speeds and lighting without an external controller. Together, the upgraded pump, cold plate, and fans deliver excellent cooling and refined acoustics in a streamlined design.
