Lian Li Galahad II Trinity SL-INF Liquid CPU Cooler Review

As I mentioned in my last AIO review, summer is in full-swing here in North America, with many parts of the country seeing temperatures above 100F. Hopefully most of us don’t endure those temperatures indoors, as our AC units work to keep us cool by removing humidity and heat from the air and pumping in cool, dry air. Stepping over to the PC realm, an all-in-one liquid cooler’s job is to keep a CPU cool by transferring heat from the CPU via what is often known as a coldplate or waterblock, and sending it over to a radiator via a closed loop of fluid in order remove the heat from the loop and return cooler liquid back to the CPU to start the process again. Lian Li is probably most noted for their contributions to the PC case world, but they have been offering AIO coolers for a while now, and have just released their latest version, the GA II Trinity SL-INF 360. As part of the Galahad series, the GA II Trinity SL-INF 360 utilizes a 360mm radiator along with three of their SL-Infinity 120mm fans, paired up with a customizable pump housing. There is a ton of customization that can be done to this cooler from both a lighting and physical design aspect, and I will cover these options within this review. Keep on scrolling to get a better look at the GA II Trinity SL-INF 360 and to see how it performs.

Special thanks to Lian Li for providing the GA II Trinity SL-INF 360 review sample!

As with pretty much every other AIO, the GA II Trinity SL-INF 360 is housed in a rectangular cardboard box featuring a product image and naming information on the top/front. This design gives potential buyers a good idea of what is to be expected visually from the cooler, and also highlights a few of the cooler’s features like ARGB lighting on the fans and pump housing, as well as the white components, 5-year warranty, and compatibility with the L-Connect 3 software via the included hub.

The back side of the box shows off the three interchaneable looks for the pump housing that can easily be swapped out at any time, along with multiple additional images highlighting some of the unique features on the cooler.

Inside, I found the AIO neatly stored in a molded cardboard tub, like most other manufacturers use.

Included with the GA II Trinity SL-INF 360 is a variety of mounting hardware for multiple AMD and Intel sockets and mounting types, as well as a short installation guide, which I will expand on later on.

Also included is the L-Connect 3-compatible hub and associated cabling. In order to support the multiple physical layouts of the pump housing, there are a few additional aesthetic components that are also included, that I will go into more detail about in a bit.
