The Coming of Winter The Poseidon Ultra ARGB stands at the pinnacle of PC liquid cooling. Its Vortent radiator fan achieves the perfect ratio of performance and silence, with its unique frame design generating a vortex effect that optimizes airflow and air pressure. The water cooling block pushes the limits of conduction tech, simultaneously reducing cooling plate thickness and increasing cooling fin surface area, as well as boosting coolant flow speed. * Support the latest AMD AM5 and Intel LGA1851 CPU sockets. The Coanda Effect Defined as the tendency of a fluid jet to stay attached to a convex surface, this principle of fluid mechanics is the science behind the Poseidon Ultra ARGB’s fan frame design: convex ridges generate a vortex, concentrating airflow velocity to maximize its cooling effect. Perfectly Balanced In regular fans, performance is inversely proportional to noise: the stronger the performance, the louder the fan.
