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.

IP5X-Certified Dust Resistance
Longer Fan Lifespan
The fans in ROG Poseidon graphics cards are certified under the International Protection Marking (IP code) as IP5X dust resistant for improved reliability and a longer lifespan. This stringent certification process ensures ROG Poseidon graphics cards provide optimal fan performance, even under severe conditions.
ASUS FanConnect II
Optimal System Cooling
ASUS FanConnect II features two 4-pin, hybrid-controlled headers that can be connected to both PWM and DC system fans for optimal system cooling. The connected fans reference both the GPU and CPU, operating automatically based on the one with the higher temperature. A comprehensive set of tuning options allow you to tune fan speeds for efficient cooling.
GPU Tweak II lets you easily set these ASUS FanConnect II modes
Auto mode

Chassis fan speeds reference GPU temperatures and operate based on the default factory setting.

Manual mode:

Allows you to set a fixed speed for connected fans.

User-defined mode

Allows you to set chassis fans to reference either the CPU or GPU temperature to determine rotational speed. Additionally, a smart, automatic calibration routine senses the controllable range of connected fans and allows you to fine-tune speeds for efficient cooling and low noise.
