A Closer Look

Like most all-in-one liquid coolers, the radiator used for the ROG Ryujin II 360 is pretty basic. It is essentially the bog-standard unit used on pretty much every Asetek AIO with only the ROG added on the side setting it apart. The sleeved tubing and fittings remain unchanged compared to the majority of other units, but that isn't really a hit on quality; it is just something I would expect to have been visually improved considering the unit's hefty price tag. Still, I can also respect the "if it's not broke, don't fix it" side of the equation. When it comes to the radiator's heat dissipation potential, it has a fins-per-inch count of 20. This is pretty typical for AIO liquid coolers, and ASUS doesn't buck the trend here, either. As for the tubing, it is 380 mm or roughly 15-inches long.


The pump is where things get more interesting. On top is a 3.5-inch full-color display, and inside the housing is an embedded fan that has a maximum RPM of 4800, and yes, it gets loud. When it comes to the pump, it is an Asetek 7th gen unit with an RPM range of 800 to 2800. The fittings for the tubing are of the swivel variety, and thanks to the wiring extruding at a corner, they have a fairly decent range to orient the tubing as needed. In a unique twist, the entire LCD and pump cover can be removed relatively easily—it simply lifts off. Compared to the MSI MPG CORELIQUID K240, the ASUS ROG Ryujin II pump cover has better fitment and is much more robust.


The copper cold plate is nothing new here, but the finish is quite good. Machining marks are visible, but cannot be felt, and I noticed no tarnish or other abnormalities.


Part of the system's high cost can be attributed to the high quality of the fans. Rather than using generic spinners, ASUS opted for Noctua's IndustrialPPC NF-F12 fans which have a maximum RPM of 2000. While the embedded fan will likely be the loudest part of the unit, these Noctua offerings should deliver good performance and noise characteristics, but more on all of that later.
