ASUS ROG RYUJIN III 360 liquid cooler 3.5 LCD Asetek 8th Gen 3x Noctua 2000 PWM 120mm

3.5-inch LCD all-in-one liquid cooler

The ASUS ROG RYUJIN III 360 is a closed-loop liquid CPU cooler built around a 3.5-inch LCD screen that shows live system data or custom animated GIFs. It uses an 8th Gen Asetek pump paired with a copper cold plate whose contact surface is 32% larger than the previous design. Three 120 mm Noctua PWM fans spin up to 2000 RPM and deliver 71.6 CFM each at 29.7 dB(A). The radiator measures 399.5 x 120 x 30 mm and uses aluminum fins with braided-mesh sleeved tubing enlarged to a 7 mm inner diameter.

360 mm radiator clearance and fan-header limits

A 360 mm radiator needs a case that can fit a 399.5 mm long, 30 mm thick core plus 25 mm fans on one or both sides. The three included 120 mm fans connect through a single 1-to-3 PWM splitter cable, so the motherboard must supply enough current on one CPU or AIO fan header for all three fans combined. The embedded VRM fan inside the pump block draws power from the same header through the splitter, adding to that load. Tubing length is fixed by the pre-filled loop and cannot be extended or shortened.

Motherboard socket bracket and VRM fan clearance

Before ordering, verify that the supplied bracket kit includes the correct mounting hardware for your specific CPU socket. The pump block measures 89 x 91 x 101 mm and the embedded axial-tech fan sits on top of it; tall motherboard heatsinks or VRM covers immediately adjacent to the socket may interfere with that fan or prevent the block from seating flat. The pre-applied thermal compound is intended for a single installation, so have replacement paste ready if you need to re-seat the cooler.
