## Long description

The Cooler Master MasterLiquid 240 ATMOS is a liquid cooling kit designed for efficient CPU cooling in desktop PCs. The 240 mm radiator with dual 120 mm SickleFlow Edge fans, a refined dual-chamber pump and ARGB Gen 2 lighting deliver balanced thermal performance and flexible visual customization. The unit is finished in black and includes tube clips and pre-installed fans for simplified installation.
Advantages
The refined dual-chamber pump increases water pressure and optimizes flow to the CPU hot spot, while fully automated pump production ensures consistent quality. Pre-installed SickleFlow Edge 120 mm fans provide quiet, effective airflow across the radiator. The pump top cover is customizable with 3D-printed designs and the ARGB Gen 2 lighting is fully controllable. Eco-friendly materials and reduced packaging size contribute to a lower environmental impact.

How to use
Unbox the MasterLiquid 240 ATMOS and verify all components are present, including the radiator, pre-installed SickleFlow Edge fans, pump unit with customizable top, tube clips and mounting hardware. Mount the radiator and fans in the case, attach the pump to the CPU socket using the appropriate bracket for your platform, secure tubes with the included clips, and connect power and ARGB headers to the motherboard or controller. Install the MasterCTRL software to configure fan curves and ARGB lighting as needed.
Usage recommendations
Install in a case with sufficient clearance for a 240 mm radiator and ensure good intake/exhaust airflow. Use the included tube clips to prevent stress on fittings. For quieter operation, configure a moderate fan curve in MasterCTRL; for lower CPU temperatures, increase fan speed under load. Keep the radiator and fans free of dust for sustained performance.
