ASUS Republic of Gamers RYUJIN III 240 ARGB AIO Liquid CPU Cooler

The ASUS ROG RYUJIN III 240 ARGB is a liquid CPU cooler built for PC enthusiasts who want dependable thermal performance, quiet operation, and a touch of personality inside the case. It pairs a radiator that measures 240 mm and is made of aluminum with an eighth-generation Asetek pump, delivering steady cooling headroom for today’s multi-core processors.

The pump relies on a three-phase motor that moves coolant efficiently between the water block and radiator. A copper cold plate that is 32 percent larger than the previous design draws more heat away from the CPU, while an embedded fan guides airflow toward the VRM area to keep power-delivery components stable during overclocks or extended workloads.

Two fans that measure 120 mm attach to the radiator through connections that are magnetic and allow daisy chaining. Each fan supports PWM control and addressable RGB lighting, so you can fine-tune the balance of airflow, noise, and style to match the rest of your build.

A 3.5-inch full-color LCD crowns the pump top. With 32 MB of onboard memory, it can display real-time temperatures, clock speeds, or custom animations that you load through Armoury Crate. System information stays visible at a glance, whether you are mid-game or deep in a render queue.

Sleeved rubber tubing runs 400 mm to give flexibility for front- or top-mounted installations in most mid-tower and full-tower cases. Included brackets cover Intel LGA 1700, 1200, and 115x sockets along with AMD AM5 and AM4, making the cooler a straightforward fit for new builds or upgrades.
