Innovative design with triple water flow pump
The innovative way to prevent pump overload by: separating the refrigerant inflow and outflow into three flow paths. Maximum cooling performance by minimizing residual liquid. 32mm 7-blade cooling fans to increase coolant flow and speed.

Unique design from ZALMAN
Sphere Pump lid design with addressable RGB lighting effects. The Alpha attracts the attention of users with different and aesthetic effects. Zalman brings a unique design to life with the Alpha series.

Fascinating Sphere Pump Cover
Planet-inspired pump cover design. It grabs the user's attention with different lights and provides visual satisfaction through the addressable RGB effects.

360° rotatable water block housing
Alpha Water Block is designed to rotate 360°. It can rotate freely according to the direction of the tube and the location of the logo. The radiator can be mounted in different positions.

Perfect synchronization ARGB
Exclusive design with ARGB effect. Control your ARGB with motherboard that supports 3-pin 5V RGB SYNC. The impact of ARGB lighting allows harmonized lighting effects.

Anti-Vibration Rubber Pads
The housing is made of a robust material. It has excellent durability and anti-vibration rubber pads for the occurrence of the fan operation.

ARGB controller
The ARGB controller allows users to switch LED mode, colors and speeds when using a motherboard without a 5V addressable RGB header. Users can switch different colors and LED speed options.

Aluminum radiator with maximum heat dissipation area
Heat dissipation fins in aluminum radiator provide great airflow. Rapid cooling of coolant. Mounting holes on both sides for easier installation. Pull and push setup for maximum airflow.

How to use

Install the radiator in the case using the supplied mounting holes and choose a pull, push or push-pull fan arrangement for optimal airflow. Fit the pump/water block onto the CPU socket and rotate the housing as needed to orient tubing and the logo. Connect fans and pump to the motherboard headers or to the provided ARGB controller; use the 3-pin 5V header on compatible motherboards for synchronized ARGB control. Apply the supplied thermal compound to the CPU before mounting the water block.

Recommendations

Use PWM fan and pump control via motherboard software or BIOS to balance cooling performance and noise. Ensure the radiator is mounted so airflow is not obstructed and check tubing orientation after installation. If the motherboard lacks a 5V ARGB header, use the included ARGB controller to adjust lighting modes and speeds.
