What this cooler is and who it fits

The COUGAR Poseidon Vistek ARGB 240 is an all-in-one liquid cooler with a 240 mm radiator and two 125 mm PWM fans. It mounts on AMD sockets from AM2 through AM5 and Intel sockets from LGA115X through LGA1851. The 1.9-inch digital display shows live temperature and speed data, while the rotatable pump head lets you orient the screen for easy reading.

The spec that decides fit

Clearance is defined by the 243.6 x 125 x 25 mm fan frame and the 390 mm tube length, so the case must accept a 240 mm radiator with those exact dimensions. The copper cold plate and aluminum radiator connect to standard 4-pin headers, and the package includes brackets for every listed AMD and Intel platform.

Behaviour under sustained load

Fans run between 700 and 2500 RPM, pushing up to 78.2 CFM at a maximum of 38 dB(A). The UTTERIGHT fin geometry enlarges the dissipation area, and PWM control keeps airflow matched to load rather than spiking to peak speed only in short bursts.

Questions about this item

What does the 1.9-inch digital display show while the PC is running?

It provides real-time system monitoring readouts so you can track performance metrics directly on the pump head.

How does the 4-pin PWM fan connector control the 700-2500 RPM range?

The motherboard adjusts voltage on the 4-pin header to vary speed between 700 and 2500 RPM, capping airflow at 78.2 CFM and noise at 38 dB(A).

Will the 243.6 x 125 x 25 mm radiator and 390 mm tubes fit my case?

The 240 mm radiator needs a 243.6 mm by 125 mm mounting area with 25 mm thickness, and the 390 mm tubes must reach from the CPU socket to that location.
