ALSEYE M240 Plus II ARGB 240mm CPU Liquid Cooler (Black)

The Alseye M240 Plus II ARGB is a 240 mm all-in-one CPU liquid cooler finished in black, designed to deliver efficient thermal management alongside customisable addressable RGB lighting. At its heart is a copper cold plate machined with 90 skived fins and expanded micro water channels, maximising the surface area in contact with the coolant and accelerating heat transfer away from the processor. Two included 120 mm PWM fans spin between 800 and 2000 RPM, adjusting speed automatically in response to system load. At minimum speed the noise floor sits at 24.2 dB(A), while maximum output reaches 37.3 dB(A) — keeping acoustics reasonable across both idle and peak workloads. Each fan moves between 38.75 and 77.65 CFM of airflow at static pressures ranging from 0.56 to 2.23 mmH2O, pairing effective radiator throughput with quiet daily operation. The fans use hydraulic bearings for longevity. The pump head features a ceramic bearing and a three-phase motor for stable, long-life operation. A thermal-conductive protection film inside the cooling loop guards the cold plate and tube inner wall against chemical interaction with the coolant, addressing both performance and leak-resistance simultaneously. The aluminium radiator measures 276 × 120 × 27 mm, with high-density "W"-profile fins at 20 mm height to enlarge the heat-exchange surface without altering the unit's overall footprint. The cooler connects to the motherboard via the 5V ARGB header, allowing lighting synchronisation through compatible ARGB software and controllers. Compatibility spans an extensive range of mainstream platforms: Intel LGA 1700, 1200, 1366, 2011, 2066, 115X, and 775 (including 13th Gen CPUs), as well as AMD AM5, AM4, AM3, AM2+, AM2, FM2, and FM1 sockets.
