Alongside its anniversary motherboard, ASUS has shown the ROG Ryujin 360 Edition 20 liquid cooler. The unit was developed specifically for the ROG Crosshair X870E Edition 20 and ships with it, and its role goes beyond that of a conventional all-in-one: the loop draws heat from the CPU and from the board's power stages at the same time.

Pump and coldplate

At the centre of the system sits an Asetek EMMA Gen10 V3RX pump. The coldplate is machined from 99.95 percent pure copper with a microfinned surface that increases contact area with the coolant. A copper heatsink sits beside it, working on the VRM area.

According to ASUS measurements, the arrangement lowers MOSFET temperatures by 40 °C and CPU temperatures by roughly 10 percent compared with cooling those areas separately.

Radiator and fans

The radiator is noticeably thicker than typical 360 mm units at 40 mm rather than the usual 27 mm, with a 20 FPI fin density and a non-louvered design. ASUS calls the channel layout Counter-Cross Flow Hex, routing coolant through the radiator in a pattern that increases heat dissipation area.

The bundled fans spin between 500 and 2600 rpm, delivering 95.65 CFM of airflow and 5.71 mmH2O of static pressure. Because of the radiator's thickness, ASUS notes that third-party cases need at least 70 mm of clearance at the mounting point.

ASUS AIO Q-Connector replaces separate pump, fan and display cables with a single connector, simplifying assembly.

Two swivelling curved 6.67-inch AMOLED panels show system data, and Display Sync-Up Mode aligns their visuals with the ROG Astral GeForce RTX 5090 Edition 20 graphics card.

The ROG Ryujin 360 Edition 20 was introduced on June 2, 2026 at Computex in Taipei as part of the ROG Edition 20 anniversary lineup.
