Liquid cooler with 3.5 LCD

The ASUS ROG RYUJIN III 240 is an all-in-one liquid CPU cooler built around a 240 mm radiator and a full-colour 3.5 LCD. It targets enthusiasts who want real-time system monitoring and personalised animations directly on the pump head. The unit ships new and includes three 120 mm magnetic daisy-chainable ARGB fans for simplified cable routing.

Magnetic fans and included AIDA64 Extreme

Magnetic daisy-chainable fans reduce wiring clutter by linking power and ARGB signals through a single chain. An embedded VRM fan inside the pump housing directs airflow toward the motherboard voltage regulators. A bundled AIDA64 Extreme licence enables detailed hardware diagnostics and sensor logging that can be shown on the LCD.

Clearance and software before ordering

Verify that your case supports a 240 mm radiator and that the pump block fits your CPU socket without blocking memory slots or VRM heatsinks. The LCD and lighting effects are configured through ASUS software, so confirm operating-system compatibility for the personalisation features. The embedded VRM fan requires an available header or splitter on the motherboard.

Questions about this item

Will the embedded VRM fan or the 120 mm radiator fans need replacement first?

The embedded VRM fan and the three 120 mm daisy-chainable ARGB fans are the only moving parts; all share similar bearing life, so whichever accumulates the most dust or runs at the highest duty cycle will tend to wear first.

What thermal limit appears first when the 240 mm radiator runs continuously at full load?

The 240 mm radiator surface area and the Asetek 8th Gen pump flow rate together set the ceiling; once coolant temperature stabilises, the CPU hits its own thermal junction limit before the loop can reject more heat.

How loud and hot does the 3.5 LCD plus pump assembly get during all-day operation?

The pump runs at a constant low speed while the three magnetic 120 mm fans ramp only as needed, so noise stays near idle levels and the LCD adds negligible heat to the loop.
