Cougar Poseidon Vistek 240mm ARGB White CPU Liquid Cooler with Digital Display

The COUGAR Poseidon Vistek 240mm ARGB White is an all-in-one liquid CPU cooler designed for builders who want both effective thermal management and a clear view of their system’s performance data. Mounted on the pump head is a 1.9-inch digital display that shows real-time CPU temperature, fan RPM, and CPU TDP wattage, removing the need to open monitoring software during a gaming session or a heavy workload. Cooling is handled by a 272 × 121 × 27 mm aluminium-alloy radiator with right-angle contoured fins that widen the effective surface area for improved heat dissipation. Two 120 mm PWM fans are integrated into a single-frame assembly, meaning all fan connectors route through one cable run rather than individual leads. Fan speed adjusts between 700 and 2500 RPM (±10%), delivering up to 78.2 CFM of airflow at a maximum static pressure of 5.4 mmH2O. Noise output reaches up to 38 dB(A) at full speed. Each fan draws up to 6.72 W (fan motor) and 5 W (LED), connects via a 4-pin PWM header for speed control, and uses a 5 V 3-pin ARGB header for lighting. The copper cold plate sits within a pump head measuring 70 mm in diameter and 59 mm in depth. The pump runs at 2700 RPM (±10%) on 12 V DC, consuming 2.4 W. A 390 ±5 mm tubing run connects the block to the radiator. The pump head rotates so the display can be oriented correctly regardless of how the cooler is mounted. Socket compatibility is broad: on the Intel side the unit supports LGA1851, LGA1700, LGA1200, LGA1155, LGA1156, LGA1151, LGA1150, LGA1152, and LGA1366. On the AMD side it covers AM5, AM4, AM3, AM2, FM2, and FM1. This range makes the Poseidon Vistek 240 a practical choice for recent platforms such as Intel Core Ultra 200 and AMD Ryzen 9000 series, as well as many older systems. The white colourway complements white or light-themed builds, while the 5 V ARGB lighting on both fans can be synchronised through compatible motherboard headers.
