ASUS ROG Ryujin III 240 All-in-One Liquid CPU Cooler - HighPerformance

In this review the ASUS ROG Ryujin III 240 is assessed as a high-performance AIO aimed at PC builders who want strong thermal control and an informative display. The single biggest reason to consider it is the combination of Asetek's latest 8th gen pump and two Noctua industrialPPC 120mm fans, which together deliver consistent cooling for demanding CPUs while keeping noise in check. The integrated 3.5 color LCD also gives immediate system feedback and customizable visuals, making the Ryujin III 240 a practical choice for users who value both function and presentation.

Key Features

• 3.5 Color LCD Display: The front-mounted screen shows hardware information instantly and supports custom GIF uploads with doubled file volumes for personalized monitoring.
• 8th Gen Asetek Pump: The latest pump with a 3-phase motor provides higher flow, lower impedance, and improved noise reduction for sustained cooling performance.
• Noctua industrialPPC Fans: Two 120mm industrial-grade fans deliver high airflow and stable pressure while maintaining minimal noise under load.
• Embedded VRM Fan: An integrated fan with a ring-shaped frame and optimized airflow channels reduces heat around VRM areas to protect motherboard components.
• Armoury Crate Control: Software control for pump, embedded fan, and radiator fan speeds allows fine-tuning and displays system stats or custom animations on the LCD.

Who It's For

The Ryujin III 240 is best suited for enthusiastic PC builders and gamers who need strong CPU cooling paired with a high-quality display for monitoring temperatures and system status. It is a good fit for users running high-core-count CPUs or overclocked systems where sustained thermal performance matters.

Users who prioritize an ultra-compact radiator, the absolute quietest passive solution, or those on a tight budget might look elsewhere; smaller cases or minimal cooling needs may be better served by simpler AIOs or air coolers with lower cost and complexity.

Pros & Cons

Pros

• Outstanding cooling capacity from the 8th gen Asetek pump paired with Noctua industrial fans for stable temperatures under load.
• The screen quality and customization options let users display system stats or custom GIFs directly on the cooler.
• Embedded VRM fan and improved airflow channels help reduce nearby component temperatures for a more reliable system.
• Armoury Crate integration gives straightforward control over pump and fan behavior.

Cons

• The added display and embedded fan increase complexity compared with simple AIOs and may be unnecessary for casual builders.
• Higher-end components and features make it a more premium-priced option than basic coolers.
