In a nutshell, the ASUS Ryujin provides a great look and good cooling performance. If you are looking for an individual AIO with high quality features, you should definitely take a look at the ASUS ROG Ryujin 240.
Fortunately, we also see some manufacturers focus on content features, instead of just lights and show. For example, you get two Noctua fans with the Ryujin from ASUS...
The taste has been very sweet and its OLED screen is a real step in terms of customization and system monitoring.
“With this AIO, you’ll come for the customisable OLED display but stay for its impeccable cooling.”
The Asus ROG Ryujin is a good, but naturally luxurious AIO solution at a price of 1400 lira, which can be preferred for those who prioritize something luxurious but beautiful like maximum silence and display.
Both models (Ryuo and Ryujin) have an extra feature that you practically won't find on any other AiO in the market. And that is OLED display, which can display many things. ASUS bet on a special design and super quality fans, and it's a lot to know about the price. It is high, the price/performance ratio of both ASUS AiO coolers is definitely not a strong point, but if you don't mind, then I recommend it.
As for the Ryujin, the design of the cooler has generally disappointed me, looking more like a cheaper version of Ryuo. On the other hand, it has a much quieter run that is ensured by a pair of Noctua coolers. Ryujin has greater efficiency than Ryuo through AIR Flow. Result of the measurements was beautiful and sustainable in this case 63 degrees, which is relatively decent for tested clock and processor.
