Radiator fan frame Watercool MO-RA IV 400 — compatible 200 mm fans, white

The Watercool MO-RA IV 400 radiator fan frame in white is an accessory designed to mount 200 mm fans to the MO-RA IV 400 radiator. It provides a secure and precise mounting interface that positions large-diameter fans to direct airflow evenly across the radiator surface. The frame is intended to integrate with the MO-RA IV 400 radiator housing and helps maintain consistent fan placement for reliable heat dissipation in custom PC and water-cooling configurations.

Advantages

The fan frame ensures stable attachment and alignment of 200 mm fans, reducing vibration and preventing misalignment that can diminish cooling performance. Its design optimizes airflow distribution over the radiator fins, which supports efficient heat exchange. The white finish offers a neutral aesthetic that suits many system builds and helps blend the frame with light-colored components or chassis interiors.

Suitable for

• Custom water-cooling radiators using the MO-RA IV 400 chassis
• PC builds that use 200 mm fans for quiet, high-volume airflow
• System upgrades where improved fan mounting and alignment are required
• Enclosures or test benches that accept externally mounted 200 mm fan assemblies

Key specifications

• Compatible fan size: 200 mm diameter
• Intended radiator model: MO-RA IV 400 housing
• Finish: white
• Function: fan mounting/frame for large-diameter fans to ensure even airflow
• Mounting: designed to position and secure multiple 200 mm fans over radiator surface

How to use

Align the frame with the MO-RA IV 400 radiator housing and secure it according to the radiator manufacturer’s mounting points. Install compatible 200 mm fans into the frame, ensuring that fan airflow direction corresponds to the radiator orientation for push, pull, or combined configurations. Tighten mounting hardware evenly to avoid stress on the fan housings and confirm that electrical connections for each fan are correctly routed and powered by the system.

Recommendations

Use fans rated for continuous operation at the intended RPM range and verify airflow direction before final assembly. Maintain clearance between the frame and other components to prevent obstruction of intake or exhaust paths. Periodically check mounting screws and fan bearings for wear to sustain consistent cooling performance.
