All-in-one liquid cooler Lian Li Galahad II Trinity 12 cm White

The Lian Li Galahad II Trinity 12 cm White is an all-in-one liquid cooler designed for efficient CPU cooling in modern PC builds. It combines a high-density aluminum radiator, a pump with interchangeable cap designs and integrated controller, and a 120 mm ARGB PWM fan with fluid dynamic bearings to deliver stable airflow and quiet operation. The unit is compatible with mainstream sockets including AM4 and AM5 and features a 27 mm thick radiator with 20 FPI for balanced thermal performance.

Advantages

The Galahad II Trinity improves on previous generations with redesigned components that increase cooling efficiency. The pump cap offers three interchangeable designs and dual controllable lighting rings for a customizable appearance. A daisy-chainable ARGB fan simplifies cable management while fluid dynamic bearings reduce noise during operation. The radiator's single-wave fins and 20 FPI layout reduce airflow restriction, and the 45° tubing connector allows flexible orientation during installation. The built-in pump controller supports L-Connect 3 for synchronized lighting and fan control.

Suitable for

• Gaming desktops requiring efficient CPU cooling
• Compact or white-themed PC builds where a 120 mm AIO fits
• Systems using Socket AM4 or Socket AM5 processors

How to use

Install the radiator and fan in a compatible 120 mm mounting position inside the case, then attach the pump block to the CPU socket using the provided redesigned one-piece backplate and fixed struts. Connect the fan to the pump using the short daisy-chain cable and plug the pump into the motherboard or power header as described in the manual. Use the supplied thermal paste control film and spreader to apply the correct amount of thermal compound before securing the pump. After hardware installation, install L-Connect 3 to configure lighting effects and monitor pump and fan speeds.

Recommendations

For best results mount the radiator where airflow is unobstructed and ensure the fan orientation provides a consistent flow through the radiator. Keep ARGB cables routed inside the fan frame where possible and verify compatibility with your case clearance for a 27 mm radiator and 25 mm fan stack.
