Radiator Watercool MO-RA IV 200 Front Logo aRGB — 500 mm radiator for PC cooling

Watercool MO-RA IV 200 Front Logo aRGB is a 500 mm external radiator engineered for custom liquid-cooling loops in high-performance PCs. The unit combines a dense fin stack with multiple coolant channels to transfer heat from the loop into the surrounding air. A front logo with addressable RGB lighting provides customizable illumination for visible external mounting or placement in large chassis that support wide radiators.

Advantages

The large 500 mm surface area and compact but dense fin arrangement increase thermal dissipation while allowing compatibility with multiple fan configurations. Addressable RGB on the front logo enables integration with ARGB control systems for synchronized lighting. Constructed for external or internal mounting in appropriately sized cases, the radiator supports common liquid-cooling hose fittings and is intended to improve CPU and GPU cooling when incorporated into a custom water-cooling loop.

Suitable for

• Custom high-performance water-cooling loops for CPUs and GPUs
• External radiator mounting or installation in large PC cases supporting 500 mm radiators
• Systems requiring increased coolant-to-air heat transfer capacity

Key specifications

• Length: 500 mm radiator core designed for external or spacious internal mounting
• Fin density: dense fin stack for improved heat dissipation
• Channel layout: multiple coolant channels suitable for liquid-cooling loops
• Fittings compatibility: accepts commonly used 1/4" or G1/4-type hose/barb/fitting interfaces
• Lighting: front logo with addressable RGB (aRGB) for synchronized lighting control
• Use case: intended for integration into custom water-cooling systems for CPUs and GPUs

How to use

Install the radiator in a location that accommodates its 500 mm length, either externally or in a compatible large chassis. Connect the radiator to the loop using appropriate hose and fittings compatible with 1/4" or G1/4 interfaces; ensure all connections are tightened and leak-tested before powering the system. Mount fans as required to achieve the desired airflow through the fin stack and connect the aRGB wiring to a compatible controller or motherboard header for lighting control. Fill the loop with suitable coolant, purge air, and verify flow and temperatures under typical load conditions.
