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

The ALSEYE M240 Plus II ARGB is a 240mm all-in-one CPU liquid cooler designed for enthusiasts who want effective thermal management paired with vibrant addressable RGB lighting. The cooler ships in a matte black finish that suits a wide variety of build aesthetics, and its ARGB header connects to any 5V ARGB-compatible motherboard port or standalone controller for synchronised lighting across your system. At the heart of the cooling loop sits a copper cold plate machined with 90 skived fins and multiple micro water channels, expanding the contact surface area to accelerate heat transfer away from the CPU die. The pump housing measures 65 × 67 × 83 mm and uses a ceramic bearing for quiet, durable operation. Cooling liquid is circulated through a dual-sucker system that the manufacturer states forms a thermal-protective film between the cold plate and the inner wall of the water tubes, reducing the risk of chemical interaction between the coolant and internal components. The aluminium radiator measures 276 × 120 × 27 mm. Its high-density “W”-profile fin array is 20 mm tall, increasing the conductive surface area without altering the overall radiator footprint, which aids heat dissipation under sustained loads. Two 120 × 120 × 25 mm fans are mounted to the radiator. Each fan uses a hydraulic bearing and spins between 800 and 2,000 RPM (±10%) under PWM control. At those speeds, airflow ranges from 38.75 to 77.65 CFM (±10%) and static pressure from 0.56 to 2.23 mmH₂O (±10%). Noise output is rated between 24.2 and 37.3 dB(A) (±10%), keeping the system relatively quiet at lighter workloads while scaling up when thermals demand it. Platform compatibility is broad. On the Intel side the cooler supports LGA 1700, 1200, 1366, 2066, 2011, 115X, and 775 sockets, including 13th Generation Core processors on LGA 1700. AMD support covers AM5, AM4, AM3, AM2+, AM2, FM2, and FM1 sockets, making it compatible with Ryzen 7000 series and earlier platforms. The cooler carries a 3-year manufacturer warranty.
