Since both units share this exact specification, neither product holds an advantage in terms of physical radiator footprint. You will find the same cooling potential from the radiator itself in both models. The choice between them will not depend on the size of the cooling block or the tube length, as these are identical. This is a clear tie for the radiator dimension.
Display
Each cooler includes a 3.5-inch LCD screen. This display allows you to monitor hardware information and upload customized GIF animations. The data confirms that both the ASUS ROG Ryujin III 240 and the ASUS ROG Ryujin III 240mm possess this same display size. There is no difference in the visual interface provided by the pump head. You get the same screen real estate and functionality on both units. The decision between these two models does not hinge on the display specifications. This aspect remains a tie.
Pump technology
Both coolers utilize the latest 8th generation Asetek pump. This pump features a 3-phase motor designed to deliver higher flow rates and lower impedance. The result is improved cooling performance alongside reduced noise levels. The product data indicates that both the ASUS ROG Ryujin III 240 and the ASUS ROG Ryujin III 240mm use this identical pump technology. You receive the same fluid dynamics and acoustic profile from the pump in either case. There is no distinction in the core cooling mechanism. This is a tie.
Radiator fans
The ASUS ROG Ryujin III 240 comes with Noctua iPPC-2000 PWM fans. These are industrial-grade fans known for high airflow and minimal noise. In contrast, the ASUS ROG Ryujin III 240mm uses Premium ROG ARGB magnetic daisy-chainable fans. While both fan types aim for efficient cooling, the specific models differ. The Noctua fans offer a specific airflow profile, whereas the ROG fans focus on ARGB integration. You get different fan characteristics depending on your choice.
