The Cooler Master MasterLiquid 240 Atmos II is an all-in-one liquid cooler designed for efficient CPU thermal management. It is constructed with a 240mm aluminum radiator and an ultra-low profile pump. A distinguishing feature is its integrated VRM fan module, which provides direct, active airflow to the motherboard's voltage regulator components. This targeted cooling helps maintain lower temperatures for critical components surrounding the CPU socket, contributing to overall system stability under load.
This cooler is equipped with two 120mm SickleFlow Edge fans that are PWM-controlled, allowing their speed to adjust dynamically based on thermal needs. These fans are engineered for high static pressure to effectively move air through the dense radiator fins. The unit features a white finish with Gen 2 Addressable RGB lighting on both the fans and the pump cap, which can be synchronized with compatible motherboards. Broad socket support ensures compatibility with a wide range of current Intel and AMD platforms.
