Cougar Poseidon Elite ARGB 240mm CPU Liquid Cooler

The Cougar Poseidon Elite ARGB 240mm AIO liquid cooler is engineered for enthusiasts who demand reliable thermal management and striking aesthetics in a single package. At the heart of this cooler is COUGAR’s proprietary UTTERIGHT fin technology — fins contoured at 90-degree right angles to the cold plate — which increases effective heat transfer surface area compared to conventional parallel fin designs, resulting in more efficient heat dissipation under sustained workloads. The pump head features an infinity mirror ARGB lighting design that creates a deep, layered visual effect inside your case. The pump head is fully rotatable, allowing you to orient the COUGAR logo correctly regardless of your chassis orientation or radiator mounting position. This is a thoughtful quality-of-life feature that avoids the upside-down logo problem common to fixed-head AIO designs. Two 120 mm PWM ARGB fans are included, spinning between 500 and 2,200 RPM to balance acoustics and airflow on demand. At maximum speed they move up to 62.53 CFM of air with a static pressure of 2.4 mmH2O, while peak acoustic noise is rated at 33.5 dB(A) — a competitive figure for a dual-fan 240 mm radiator. PWM control means your motherboard or fan controller can dial the speed down at idle for near-silent operation. Socket compatibility is broad, covering the current AMD AM5 and Intel LGA1851 platforms alongside older AM4, AM3, AM2, FM2, FM1, LGA1700, LGA1200, LGA115X, and LGA1366 sockets. All required mounting hardware is included in the box.
