Asus ROG Ryujin III 240mm All-In-One White Liquid CPU Cooler with ARGB Fans and LCD Screen

Why this is a deal

This white 240mm ROG Ryujin III bundles high-end cooling, addressable RGB fans, and a large pump-top LCD into a footprint that fits more cases than 280/360mm units. You’re getting flagship-style extras—the embedded VRM fan, customizable screen, and unified ASUS ecosystem control—without having to upsize your case or add separate accessories.

Best for / Not for

• Best for: White-themed builds that want a showcase LCD and ARGB without sacrificing thermal headroom.
• Best for: Mid-tower systems running modern Intel/AMD CPUs at stock or moderate OC.
• Not for: Ultra-compact cases that can’t accommodate a 240mm radiator.
• Not for: Users who dislike installing vendor software to control lighting/LCD.

Key things that matter

• 240mm radiator: The sweet spot for fit vs. performance—easier case compatibility than 280/360mm, while handling mainstream high-core CPUs with sensible fan curves.
• ARGB radiator fans: Static-pressure-optimized ARGB fans move air through dense fins and let you sync lighting across the build.
• Pump-top LCD: Displays temps, logos, or animations—useful at-a-glance telemetry without extra screens or software overlays.
• Embedded VRM fan: Moves air around the socket to trim motherboard/VRM hotspots, helpful in dense builds or low-airflow layouts.
• Socket support/build: Modern Intel and AMD compatibility and robust tubing/radiator quality are typical for this class.

Pros / Cons

• Pros: Excellent cooling for a 240mm class AIO.
• Pros: LCD + ARGB deliver both function (telemetry) and clean aesthetics.
• Pros: VRM-assist fan improves surrounding component temps.
• Cons: Full control relies on ASUS Armoury Crate, which some find heavy.
• Cons: You’re paying for showpiece features; unnecessary if you don’t want a screen/lighting.

Our take

If you want a white 240mm AIO that actually adds meaningful extras, this is near the top of the pile. Great thermals, a genuinely useful LCD, and VRM airflow make it an easy pick—provided you’re fine with ASUS software and your case supports 240mm.
