ASUS today formally launched the Republic of Gamers (ROG) Ryujin II series all-in-one liquid CPU coolers. The second generation of Ryujin was first shown off in January 2021. The production version is unchanged. Launching in two variants based on radiator size—the Ryujin II 360 and Ryujin II 240, these coolers are characterized by a 3.5-inch true-color LCD display on the pump-block, and the inclusion of premium Noctua Industrial PPC 2000 PWM fans with the package.

The screen can be made to display anything from cool animation presets, to system monitoring, real-time cooling performance, and your clan's identity. The pump-block also has a concealed lateral fan that ventilates the CPU VRM area around the socket. The pump-block is functionally based on the 7th generation of AIO CLC technology by Asetek. The included Noctua Industrial PPC 2000 fans turn at speeds of 450 - 2000 RPM, pushing up to 71.6 CFM of air-flow at 3.94 mm H₂O static pressure. The company didn't reveal pricing.

ASUS has showcased an update to their ROG Ryujin AIO, which features an LCD display that's far increased in size compared to the original's 1.77" OLED. The ROG Ryiujin 2 features a redesign of the OLED screen component (now an LCD, likely due to OLED burn-in) sitting on top of the CPU waterblock, now measuring in at a whopping 3.5", that can be user-configured to showcase ROG pre-installed graphics, system data such as temperatures, voltages, and etc, or even user-created graphics.

The ROG Ryujin II looks much the same as its predecessor, barring the new larger display. While the original sold at an MSRP of $220, the ROG Ryujin II will likely retail for higher than that. While the cooler features RGB lighting capabilities, ROG elected to showcase it in a more subdued approach, marrying the LCD graphics with the black aesthetics of its ROG Maximus Z590 Hero motherboard. A beautiful AIO loop, to be sure, although the expectedly high pricing may give would-be buyers some pause.
