ASUS added to the very long list of Republic of Gamers (ROG) branded hardware that can make up your gaming PC, with its first directly branded all-in-one liquid CPU cooler, the ROG RYUO 120 and the RYUJIN 240/360. Now, you might be thinking "hey look, it's yet another AIO cooler plastered with an ROG logo, a dash of RGB lighting, and a price-premium to make up for the brand," but pay close attention to the pump-block. It's studded with an actual 1.77-inch full-color OLED display, which shows the ROG logo out of the box, but when interfaced with software over a USB 2.0 header, it displays a host of things such as RPMs, coolant temperature, CPU temperature, a personalized logo, or even an animated GIF! This, besides an addressable RGB ring along the perimeter on the RYUO 120, and a polygonal element on the RYUJIN 240/360. If your interest is only piqued 99% by this point, allow the included Noctua IndustrialPPC fans, and M.2 SSD cooling to make up for the remaining 1% for the RYUJIN series. Not all Asetek-sourced AIO coolers are equal.
