Cooler Master MasterLiquid Atmos II LCD 240mm ARGB CPU Liquid Cooler

The Cooler Master MasterLiquid Atmos II LCD 240mm is a closed-loop all-in-one liquid cooler designed for builders who want meaningful thermal headroom alongside high-impact RGB aesthetics. At its centre sits a 2.1-inch circular LCD display (480 × 480 px, 300 cd/m², 60 Hz refresh rate) built into the pump head, letting you surface system temperatures, custom animations, or other real-time data without any secondary panel. The pump itself is engineered around Cooler Master’s patented dual-chamber design, which separates the intake and outlet flow paths to increase internal water pressure and direct coolant precisely toward the CPU heat-spreader. The housing is constructed from PPS (polyphenylene sulfide) reinforced with fiberglass — an industrial-grade thermoplastic chosen for its heat resistance — and Cooler Master states the assembly has passed endurance validation at 70 °C for 3,000 hours and 120 °C for 12 hours under controlled conditions. Pump MTTF is rated at over 210,000 hours. The ultra-low-profile pump head (92.5 × 87 × 38.5 mm) keeps vertical clearance low enough to fit a wide range of mid-tower and compact ATX cases. Two 120 mm SickleFlow Edge ARGB fans are pre-installed on the aluminum 240 mm radiator (277 × 119.2 × 27 mm). Each fan delivers up to 141.4 CFM combined airflow (240.35 m³/h total) at up to 3.61 mmH₂O static pressure, using a Loop Dynamic Bearing for long-term reliability. Fan noise tops out at 36 dB(A) at maximum speed. The pump’s noise ceiling is 25 dB(A) at its maximum 3,400 RPM (±300 RPM). Connectivity is straightforward: fans use a 7-Pin PWM + ARGB header, the pump uses a 4-Pin PWM + 3-Pin Addressable Gen2 RGB header, and the LCD connects via USB Type-C to a standard 9-pin motherboard USB header at 5 VDC. The 350 mm tube length accommodates a variety of radiator mounting positions. A quick-mount kit covers Intel LGA 1851, 1700, 1200, 1150, 1151, 1155, and 1156 sockets, plus AMD AM5 and AM4. Cooler Master includes dedicated offset mounting brackets for LGA 1851 builds, which are optimised for the heat-distribution characteristics of Intel’s latest platform. The cooler carries a 6-year warranty.
