The Cooler Master MasterLiquid 240 Atmos is an all-in-one liquid CPU cooler designed for thermal management in modern computer builds. It is equipped with a 240mm aluminum radiator and two 120mm PWM fans that operate between 690 and 2500 RPM. These fans are engineered to deliver a maximum airflow of 70.7 CFM and a static pressure of 3.61 mmH₂O, facilitating heat dissipation from the CPU. Both the fans and the dual-chamber pump utilize a Loop Dynamic Bearing, which contributes to their operational longevity and acoustic profile.
This cooler provides broad compatibility with contemporary Intel and AMD processor sockets, including LGA 1700 and AM5. The system features Addressable Gen 2 RGB lighting on the fans and pump, which can be managed with the included controller. A distinct design feature is the pump's top cover, which is removable and allows for customization using 3D-printed parts. The unit is constructed with an aluminum base plate and rubber tubing to connect the components.
