Refined Dual Chamber Pump Design
The MasterLiquid 240 Core II features Cooler Master’s upgraded G9R dual chamber pump technology, engineered to deliver superior thermal performance while maintaining whisper-quiet operation. This compact design maximises cooling efficiency by separating hot and cold liquid channels, ensuring consistent heat dissipation even under heavy loads. The pump operates at 3,100 RPM with a noise level of just 25 dBA, making it virtually silent during typical usage scenarios.
Infinity Mirror Pump Cover & RGB Illumination
The pump cover incorporates an infinity mirror design that creates a mesmerising visual effect, reflecting RGB lighting infinitely within the mirrored surface. Multi-colour illumination adds a premium aesthetic touch to your build, with the lighting system being fully customisable through compatible motherboard software. This design element transforms the pump from a purely functional component into a striking visual centrepiece for your system.
Optimised Tubing & Installation Flexibility
400mm long, reinforced tubing provides exceptional installation flexibility, allowing you to mount the radiator in various orientations without strain on the connections. The optimised tube length ensures effortless routing whether you’re installing in a compact Mini-ITX case or a full-tower setup. The daisy-chain fan connection system simplifies cable management, reducing clutter and improving overall build aesthetics.
Enhanced 120mm SickleFlow Fans
The included SickleFlow fans have been completely redesigned with new blade geometry that delivers improved static pressure and airflow. Operating between 650-1,750 RPM, these fans move 120 m³/h of air while maintaining a maximum noise level of 30 dBA. The PWM control allows for dynamic speed adjustment based on CPU temperature, ensuring optimal performance when needed while remaining quiet during light workloads.
