    Next-Gen DirectCU H2O Hybrid Cooling
    Complete flexibility with your choice of air or liquid cooling
    Next-Gen DirectCU H2O is a hybrid thermal solution that combines a vapor chamber and water channel. Compared to the previous-gen design, the DirectCU H2O's in-channel water-flow rate has been increased by 22% for better heat dissipation. The new ROG Poseidon is constructed with a larger 2.5-slot cooler, providing 40% more surface area for thermal dissipation compared to previous 2-slot designs, leading to lower temperatures and quieter performance.
    Standard G1/4-Inch Terminal Block
    With a new G1/4-inch terminal block*, the Poseidon allows you to choose from a wide variety of fittings and makes plumbing a custom water loop easier than ever.
    * Barbs need to be purchased separately.
    Make the Cooling Even More
    The ROG Poseidon features our patented wing-blade design fans that provide maximum airflow. With IP5X certification, the fan bearings are protected from dust ingress, ensuring a long lifespan. Armed with an efficient cooler and 0dB fan technology, the ROG Poseidon allows you to play light gaming sessions in complete silence and has the credentials to tackle heavier workloads with minimal noise.
    Patented Wing-Blade Design
    Max Air Flow with 105% More Air Pressure
    Patented wing-blade fans deliver maximum air flow and 105% greater static pressure over the heat sink, while operating at an up to 3X quieter volume than reference cards.
    0dB Technology
    Game in Complete Silence
    Innovative 0dB technology stops the fan completely when the GPU temperature remains below a set level*, letting you enjoy light gaming in complete silence.
