Prime LC vs Ryujin III Specs
Display size
The ASUS ROG Ryujin III 240 features a 3.5-inch LCD screen. This larger panel allows for detailed hardware monitoring and supports custom GIF animations with doubled file volumes. You can view system stats clearly without straining your eyes. The ASUS Prime LC 3-Fan ARGB also includes an LCD screen, but the specific dimensions are not listed in the published specifications. Because the Ryujin III explicitly states its larger display size, it offers a more defined visual experience for monitoring your build. If screen real estate matters to you, the Ryujin III has the clear advantage here.
Radiator size
The ASUS ROG Ryujin III 240 is built around a 240mm radiator. This size is designed for cases that support two 120mm fans in the front or top. The ASUS Prime LC 3-Fan ARGB is listed with a 3-fan configuration, which typically corresponds to a 360mm radiator. A 360mm radiator provides more surface area for heat dissipation than a 240mm unit. This means the Prime LC can potentially handle higher thermal loads by spreading the heat across more fins. If you need maximum cooling capacity for a high-end CPU, the larger Prime LC radiator is the better choice.
Fan quality
The ASUS ROG Ryujin III 240 uses embedded Noctua industrial-grade iPPC-2000 PWM radiator fans. These fans are known for high airflow and minimal noise, operating up to 2000 RPM. They also feature a ring-shaped frame design to improve airflow around the VRM area. The ASUS Prime LC 3-Fan ARGB uses chainable fans focused on static pressure and airflow, but the specific brand and performance metrics are not detailed in the provided data. Since the Ryujin III specifies premium Noctua fans with clear performance targets, it offers a more transparent quality guarantee for your build.
Pump generation
Both coolers utilize Asetek pumps for reliable fluid circulation. The ASUS ROG Ryujin III 240 explicitly features the latest 8th generation Asetek pump with a 3-phase motor. This newer pump delivers ultimate cooling performance, higher flow rates, lower impedance, and reduced noise. The ASUS Prime LC 3-Fan ARGB is described as having a powerful Asetek pump with a robust motor, but it does not specify the generation. The Ryujin III’s 8th gen pump represents a technological step forward, likely offering better efficiency and thermal transfer than the unspecified pump in the Prime LC.
Weight
The ASUS ROG Ryujin III 240 weighs 3.1 pounds. This includes the radiator, pump block, and fans. The ASUS Prime LC 3-Fan ARGB weighs 2 pounds according to the specifications. The Ryujin III is significantly heavier, likely due to its larger LCD screen and more complex pump assembly. When installing a heavy cooler, you must ensure your motherboard has adequate backplate support to prevent sagging. The Prime LC is lighter, which may reduce stress on your CPU socket during installation. If you prefer a lighter load on your motherboard, the Prime LC is the safer option.
