Radiator fan shroud EK Water Blocks EK-Loop 15 cm black

EK Water Blocks EK-Loop 15 cm black is a rigid fan shroud engineered for use with 150 mm cooling fans in PC liquid-cooling radiators and compatible chassis. The shroud channels airflow evenly through the radiator core, reducing bypass and turbulence to help maintain consistent heat transfer performance in custom water-cooling loops. Its black finish integrates with common cooling components and mounting arrangements used in enthusiast systems.

Advantages

The solid housing focuses air through the radiator core for improved cooling efficiency compared with an unshrouded fan, while minimizing recirculation and uneven flow. The design is compatible with standard 150 mm fan mounting patterns and radiator layouts, enabling simpler alignment and a neater installation. A rigid construction maintains shape under fan pressure and helps preserve consistent airflow direction over time.

Suitable for

• Custom PC liquid-cooling radiators using 150 mm fans
• Chassis installations where guided airflow through a radiator core is required
• Enthusiast builds that require precise fan-to-radiator alignment

Key specifications

• Compatibility: designed for 150 mm (15 cm) cooling fans
• Function: airflow channeling/shrouding for radiators and chassis
• Material: rigid housing (black finish)
• Form factor: 15 cm fan-sized shroud for PC cooling systems
• Application: intended for liquid-cooling radiator and chassis mounting

How to use

Position the EK-Loop 15 cm shroud so the fan aligns with the shroud's circular opening and the radiator core. Secure the shroud to the radiator or chassis using the existing fan/radiator mounting points and compatible screws, ensuring the fan blades have adequate clearance and the airflow orientation matches the cooling loop requirements. Verify that the shroud does not obstruct other components and that all mounting hardware is tightened to prevent vibration.

Recommendations

For best results, pair the shroud with a high-quality 150 mm fan rated for radiator use and verify fan direction to ensure air is pushed or pulled through the radiator as intended. Check clearance in your case and confirm screw lengths to avoid contact with the radiator fins or PCB components.
