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

The Lian Li Galahad II Trinity 12 cm Black is an all-in-one liquid cooler designed to improve CPU cooling with a larger pump housing that accommodates upgraded components and a 32 mm thick, high-density aluminum radiator with 19 FPI double-wave fins. The unit includes a 120 mm, 28 mm-thick LCP fan with a copper-shield bearing and daisy-chainable cabling, an interchangeable pump cap system with three distinct designs and dual RGB rings, and a rotatable 45° tubing connector for flexible installation. The pump integrates a controller compatible with L-Connect 3 for lighting and motor speed control.

Advantages

The Galahad II Trinity offers increased cooling capacity due to its larger pump and high-density radiator construction, while the double-stack fins and high-performance LCP fan provide improved heat dissipation and stable high-RPM operation. Interchangeable pump caps with dual lighting rings allow visual customization, and the built-in controller simplifies cable routing and software control through L-Connect 3. Installation is eased by redesigned one-piece backplates with fixed struts and supplied thermal paste control film and spreader.

Suitable for

• Cooling mainstream and high-performance desktop CPUs
• PC builds requiring compact 120 mm radiator solutions
• Systems where customizable RGB lighting is desired
• Enthusiast builds needing flexible tubing orientation and simplified cable management

How to use

Install the radiator and fan in a 120 mm mounting location in your case, attach the pump to the CPU using the provided one-piece backplate and fixed struts, and secure tubing orientation using the 45° rotatable connector to achieve the desired routing. Connect the fan to the pump using the included daisy-chain cable and attach the pump to the motherboard power headers as described in the manual. Use the supplied thermal paste control film and spreader to apply an appropriate amount of thermal compound before seating the pump block. Launch L-Connect 3 to configure lighting effects and monitor or adjust motor speed.

Recommendations

For best results, ensure good case airflow around the 120 mm radiator, verify compatibility with your CPU socket before installation, and keep L-Connect 3 up to date to access the latest lighting and control features.
