ASUS has released two ROG Ryujin closed-loop liquid coolers designed for AMD’s Ryzen and Ryzen Threadripper processors. Both AIO LCSes feature a square waterblock with an embedded OLED screen that can be used for monitoring or style/personalization purposes. In addition, the waterblock has a small fan to cool down the CPU VRMs.

ASUS’ ROG Ryujin 240 and ROG Ryujin 360 closed-loop liquid coolers rely on an ASUS-designed proprietary waterblock, and which is compatible only with AMD’s CPUs in AM4 and TR4 packaging (for now, AMD only supplies mounting brackets for contemporary AMD CPUs). ASUS does not describe design of its pump/waterblock beyond the fact that it is large, square, features an embedded 1.77-inch OLED display, as well as a microfan that can cool down surrounding components by up to 20°C, according to the maker. Meanwhile, the relatively large dimensions may indicate that the block can cover 100% of the TR4 CPU IHS (integrated heat spreader), which means efficient cooling for AMD’s latest multi-core Threadripper 2 processors for "extreme" workstations. The manufacturer does not specify the maximum amount of thermal energy its ROG Ryujin LCSes can dissipate, but good large closed-loop liquid coolers can remove upwards of 500 W of heat.
