The Cooler Master MasterLiquid 240 Atmos is an all-in-one liquid cooling system designed for efficient CPU thermal management. It utilizes a refined dual-chamber pump paired with a 272mm aluminum radiator to effectively dissipate processor heat. Two 120mm SickleFlow Edge fans are engineered to generate high static pressure for optimal airflow through the radiator fins. Fan speeds are automatically adjusted via PWM control to balance cooling performance with acoustic output, and the unit uses an aluminum base plate for thermal transfer from the CPU.
This cooler incorporates ARGB Gen 2 lighting on the pump and fans, providing customizable illumination managed through the included controller or compatible software. A distinguishing feature is the pump's modular top cover, which can be removed and replaced with custom 3D-printed designs for extensive personalization. All performance metrics and lighting effects can be monitored and adjusted using the MasterCTRL software utility. The system includes mounting hardware for a wide range of current Intel and AMD sockets, ensuring broad compatibility for new builds and upgrades.
