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

The Lian Li Galahad II Trinity 120 mm All-in-one liquid cooler in black combines a compact 120 mm ARGB PWM fan, a high-density 27 mm aluminum radiator, and a pump with interchangeable cap designs to provide efficient CPU cooling for gaming and workstation systems. It uses fluid dynamic bearings for reliable, quiet fan operation and supports mainstream sockets including AM4 and AM5. The pump integrates an ARGB controller compatible with L-Connect 3 for lighting and motor speed control, and the package includes a thermal paste control film and spreader to simplify correct thermal paste application.

Advantages

The Galahad II Trinity offers improved thermal performance over its predecessor thanks to revised design elements such as a single-wave fin radiator with 20 FPI and a 27 mm thickness that reduces airflow restriction. The pump cap provides three interchangeable looks and independently controllable dual lighting rings. Fans use fluid dynamic bearings for long life and low noise, and can be daisy-chained with short cables hidden inside the frame to simplify wiring. A 45° tubing connector allows 360° rotation for flexible installation, while redesigned one-piece backplates with fixed struts increase mounting convenience and compatibility.

Suitable for

• High-performance gaming PCs

How to use

Mount the radiator in a suitable 120 mm location in your case, orienting fins and airflow for optimal intake or exhaust as required. Attach the pump block to the CPU using the included one-piece backplate and fixed struts for your socket type (AM4 or AM5). Connect the ARGB PWM fan to the pump via the supplied daisy-chain cable, then connect the pump to the motherboard power and ARGB headers or control it with L-Connect 3. Apply the supplied thermal paste control film and spreader to ensure an even, correct amount of thermal compound before securing the pump head.

Recommendations

For best cooling results, install the radiator where airflow is unobstructed and ensure fans are oriented to create consistent case airflow. Use L-Connect 3 to monitor pump speed and adjust lighting effects; verify compatibility with your case layout when planning a 120 mm AIO installation.
