## Long description

The Lian Li Galahad II Trinity 12 cm all-in-one liquid cooler is designed for high-performance gaming and enthusiast PC builds. The cooler integrates a 120 mm ARGB PWM fan with 89.1 CFM airflow and 3.66 mmH2O static pressure, a 27 mm thick aluminum radiator with single-wave fins and 20 FPI, and a pump unit with interchangeable cap designs and built-in controller. The unit supports modern AMD sockets and comes in a black finish, combining thermal performance, customizable lighting and flexible installation options for compact and full-size cases.
Advantages
The Galahad II Trinity improves on previous designs by increasing thermal efficiency through a high-density aluminum radiator and optimized fin pattern that reduces airflow restriction. The included 120 mm fan uses fluid dynamic bearings for quieter operation and longer life while delivering the specified airflow and pressure. The pump offers three interchangeable cap styles and dual lighting rings for adaptable aesthetics, and the integrated controller with L-Connect 3 compatibility simplifies lighting and pump speed management. Flexible tubing with a 45° connector and redesigned one-piece mounting backplate streamline installation and orientation inside a variety of cases.
Suitable for
 High-performance gaming PCs that require effective CPU cooling
 Compact builds where a single 120 mm radiator is preferred
 Systems that benefit from ARGB lighting and centralized controller management
 Upgrades from stock air coolers to improve thermal headroom and acoustics

How to use
Prepare the mounting area by removing any existing cooler and cleaning the CPU surface. Attach the supplied one-piece mounting backplate and fixed struts according to the socket type, apply thermal paste using the included control film and spreader to ensure an even layer, and secure the pump block onto the CPU. Mount the 120 mm radiator in the chosen case location, route the tubing using the 45° connector freedom to avoid kinks, and connect the ARGB PWM fan(s) to the pump controller using the short daisy-chain cable. Connect the pump and lighting headers to the motherboard or controller and configure pump speed and lighting through L-Connect 3.
Usage recommendations
For best cooling performance, install the radiator where it can receive unobstructed airflow and set fan curves in the motherboard or L-Connect 3 to balance noise and thermal performance. Use the included thermal paste control film to apply the correct amount of paste. Ensure ARGB headers and cables are connected according to the motherboard manual when synchronizing lighting effects.
