All-in-one liquid cooler Corsair Nautilus 240 RS LCD 12 cm White

The Corsair Nautilus 240 RS LCD is an all-in-one liquid cooler designed for compact high-performance PCs. It features a bright 2.1" 480 x 480 IPS LCD on the pump head that can display CPU temperature, animated GIFs, logos and more at 30 FPS with a 600 cd/m² backlight and 16.7 million colors. The unit includes a refined pump with a three-phase motor and a precision cold plate for improved thermal transfer, plus high-static-pressure RS120 fans for efficient airflow through the radiator. Installation requires a single USB 2.0 9-pin header connection to power and control the LCD.

Advantages

The cooler delivers efficient, low-noise thermal performance thanks to a high-flow, quiet pump that operates around 20 dBA and supports PWM fan control with Zero RPM mode. The slightly convex cold plate and optimized thermal paste application maximize contact with the CPU integrated heat spreader for consistent cooling. The 2.1" IPS display adds customization and monitoring options via CORSAIR iCUE with built-in GIPHY integration for animated content.

Suitable for

• Gaming desktops and compact high-performance PCs
• Systems requiring a 120 mm (12 cm) radiator solution
• Users who want on-pump temperature monitoring and customizable LCD content

How to use

Mount the radiator and fans in your case according to available 120 mm mounting points. Apply mounting hardware to the pump head and align the slightly convex cold plate over the CPU integrated heat spreader. Connect the pump and fans to the motherboard: attach the fan cables to a 4-pin PWM header (fans can be daisy-chained) and connect the pump LCD cable to an available USB 2.0 9-pin header to power and control the display. Use thermal paste applied in the supplied optimized pattern and fasten the pump bracket to complete installation.

Recommendations

For balanced noise and cooling, enable PWM control in BIOS or via CORSAIR iCUE and use Zero RPM mode at low loads. If you plan to use advanced display features or GIFs, install CORSAIR iCUE and connect the pump to a USB 2.0 header; for multi-device control consider a compatible iCUE controller (sold separately).
