ASUS ROG RYUJIN II 360 CPU Cooler Review: Core i9-12900K Update - Ryujin II

Update 11/11/2021: This review was originally published in June 2021 close to the Intel Rocket Lake CPU launch. We are now updating it to include our 12th-gen Intel Core CPU testing aka Alder Lake with the Intel Core i9-12900K as the ROG Ryujin II 360mm is included in the ROG Z690 review package. We advise anyone reading this review to get themselves up to speed with Alder Lake as well checking our review of the Intel Core i9-12900K. For the ROG Ryujin II 360mm AIO, the rest of the review will remain untouched and will only include an addition to our conclusion regarding the 12900K as well as its own section. The original review published July 2021 follows:


The ASUS ROG Ryujin cooler was one of the first coolers to not only include to not only have a full LCD display on the waterblock but also collaborate with Noctua for their fans. Our review of the original ROG Ryujin would show it still holds up to today’s modern CPUs but as good as it was, there was a few things that original Ryujin needed correcting: its OLED screen and its unused pump/block size. That changes today as ASUS recently released the ROG Ryujin II AIO cooler. It retains much of what makes the original Ryujin a great cooler but improves the overall aesthetic with a larger LCD display as well as including some distinctive extras in the package.
