Lian-Li Galahad II Trinity SL-INF 360mm AIO Cooler - Quiet Performance

Our review of the Lian-Li Galahad II Trinity SL-INF 360mm All-In-One cooler finds it best suited to PC builders who want strong cooling with style options. The Galahad II Trinity delivers meaningful temperature drops thanks to its single-stack fin radiator and pre-installed fans, while the interchangeable pump caps and ARGB options let users tailor the look. Installation is straightforward for those familiar with AIOs, and the inclusion of UNI FAN SL-INF compatibility makes it a sensible choice for builders who want a visually unified fan setup.

Key Features

• 360mm single-stack radiator: Provides a balance of high heat dissipation and compatibility with most full-tower and many mid-tower cases.
• Pre-installed fans: Saves time during build and ensures the radiator is ready to mount out of the box without sourcing separate fans.
• ARGB and UNI FAN SL-INF options: Lets builders choose between high-performance RGB fans or matching UNI FAN SL-INF fans for a cohesive case aesthetic.
• Interchangeable pump caps: Three pump cap designs let users customize the top of the pump with different looks and two independently controllable color rings.
• 45 degree rotary fittings: Improve hose routing and reduce stress on fittings for cleaner cable and loop management inside the case.
• L-Connect 3 control compatibility: Offers software control of lighting and some pump/fan behavior for users who want centralized tuning.

Who It's For

The Galahad II Trinity SL-INF 360mm is aimed at PC enthusiasts and gamers who need substantial cooling for modern CPUs and who care about aesthetic customization. It is a good fit for builders with full-tower or roomy mid-tower cases who value an easy install and a polished ARGB presentation.

Those on very tight budgets or owners of small form-factor cases should look elsewhere, since the 360mm radiator requires room and is priced for builders prioritizing performance and looks rather than bare-bones cost efficiency.
