Lian Li Galahad II Trinity 360MM AIO Liquid Cooler - ARGB Pump Caps

In this review of the Lian Li Galahad II Trinity 360MM AIO liquid cooler, the bottom line is clear: this is a strong choice for builders who prioritize cooling capacity and custom lighting. The triple 120mm radiator and larger tube diameter deliver measurable thermal headroom, while the interchangeable pump caps and individually controllable lighting rings give system builders a high degree of visual customization. Installation is straightforward thanks to the 45-degree tubing connector and broad socket compatibility, making it a sensible pick for many Intel and AMD systems.

Key Features

• Interchangeable pump caps: Three distinct cap designs each offer two independently controlled lighting rings for flexible ARGB styling to match a build.
• 27mm radiator thickness: A relatively thick 397.5 x 119.2 x 27mm radiator provides greater cooling surface area for improved thermal performance under sustained load.
• Improved internal flow: Larger tube diameter and 13% wider copper plate fin spacing reduce buildup and increase water flow for faster heat transfer.
• High-performance fans: Included 120 x 120 x 25mm fans use fluid dynamic bearings and up to 2,100 RPM to deliver strong airflow and static pressure across the radiator.
• Easy installation: The 45-degree tubing connector enables 360 tube rotation and the mounting backplates support Intel LGA 1700/1200/115x and AMD AM5/AM4 sockets for broad compatibility.

Who It's For

The Galahad II Trinity is best for PC builders running mid to high-end CPUs who want a 360mm AIO with a combination of serious cooling capacity and standout ARGB customization. Enthusiasts who value a clean visual presentation and the ability to swap pump caps for different looks will appreciate the included options and lighting rings.

It is less well suited to small-form-factor builds that cannot accommodate a 360mm radiator, or to buyers for whom the quietest possible operation is the single top priority, since customer reports about noise are mixed. Those needing integrated display or controller features beyond ARGB may want to compare alternatives.

Pros & Cons

Pros

• Excellent thermal capacity from a 360mm radiator and improved water flow for sustained cooling.
• Strong aesthetic flexibility with three pump cap designs and independently controlled lighting rings.
• Quality fans with fluid dynamic bearings provide stable long-term operation and effective airflow.
• Wide socket compatibility and thoughtful tubing connector design make installation straightforward.

Cons

• Some users report mixed noise experience, so operation may be louder on certain systems or settings.
• The 360mm radiator requires ample case space and is not suitable for compact enclosures.

Our Verdict

The Lian Li Galahad II Trinity 360MM is a compelling option for builders seeking strong cooling performance and high-quality ARGB presentation. It offers a thoughtful combination of larger flow paths, a capable radiator, and flexible pump cap lighting, delivering good value for mid and high-end builds that can fit a 360mm radiator. Buyers who need the absolute quietest pump or a small case alternative should compare quieter or smaller units.

Frequently Asked Questions

Will this fit an Intel LGA 1700 socket?
Yes, the cooler includes mounting support for Intel LGA 1700 along with 1200 and 115x sockets.

Are the fans daisy-chainable or replaceable?
The included 120mm fans support daisy-chainable ARGB and use fluid dynamic bearings; they can be swapped for compatible 120mm fans if desired.

Is installation difficult for first-time builders?
Installation is generally straightforward due to the 45-degree tubing connector for rotation and supplied mounting backplates, but a 360mm radiator requires sufficient case space and two people can make mounting easier.
