ASUS ROG RYUJIN III 240 ARGB WHT liquid cooler

240 mm all-in-one liquid CPU cooler

The ASUS ROG RYUJIN III 240 ARGB WHT is a closed-loop liquid cooler with a 279.5 mm radiator and two 120 mm magnetic ARGB fans. A copper cold plate and an 8th generation Asetek pump circulate coolant through aluminum channels. A 3.5 inch LCD screen on the pump block shows live hardware data or custom GIF animations. Armoury Crate software controls pump speed, embedded fan speed, radiator fan speeds and display content. A one-year AIDA64 licence is included for advanced monitoring.

Builders who want integrated monitoring and lighting

This cooler suits builders who want a white-themed loop with a built-in display for temperatures, clock speeds or personalised animations without adding separate sensors or screens. The daisy-chain fan design reduces cable clutter inside the case. It is not for systems that lack a 120 mm dual-fan mounting location or for users who prefer air cooling without liquid maintenance considerations. Buyers needing a larger radiator surface or a different block colour should look at other configurations.

240 mm radiator capacity and thermal headroom

The 279.5 mm radiator paired with two fans running up to 2200 RPM delivers 70.07 CFM airflow at 36.45 dB(A) noise. This capacity comfortably handles modern desktop CPUs at stock and moderate overclock settings. Under sustained heavy loads the coolant temperature will rise until the radiator reaches equilibrium, limiting further frequency headroom. The copper block and high-flow pump delay that point, but the 240 mm surface area remains the ultimate thermal ceiling for extreme continuous workloads.
