Fan grill Noctua NA-FG1-20 SX5 Steel 20 cm 154 x 154 mm

The Noctua NA-FG1-20 SX5 is a premium-grade steel fan grill designed for 200 mm (20 cm) fans with a mounting hole pattern of 154 x 154 mm. Supplied in a set of five with mounting screws and Noctua’s tool-free push-pin system, this grill protects the fan and cables while minimising impact on airflow and acoustic performance. The offset design with rounded struts and a matte-black finish with a central Noctua logo provides robust protection and a discreet, quality appearance.

Advantages

The dense, sturdy steel ribs reliably prevent fingers or cables from reaching the spinning impeller, while the offset layout with rounded struts reduces turbulence noise and preserves airflow. The included push-pin mounting system allows tool-free installation and adds a 5 mm offset for improved inflow smoothness and quieter running. Regular black-coated screws are also included for applications requiring a stronger attachment.

Suitable for

• Protecting 200 mm PC fans from accidental contact and debris
• Acoustic optimisation of fan intake/exhaust in computer cases
• Systems requiring tool-free, quick grill installation or extra offset spacing
• Setups where a matte-black, discreet visual match to Noctua fans is desired

Key specifications

• Model: Noctua NA-FG1-20 SX5
• Type: Fan grill (steel)
• Fan size compatibility: 200 mm (20 cm)
• Mounting hole pattern: 154 x 154 mm

How to use

Insert the supplied rubber plugs into the fan’s mounting holes, place the grill over the fan so the holes align, then secure the grill by pushing in the plastic push-pins. If desired or required, use the included black-coated screws to fasten the grill or the fan itself. To achieve the acoustically optimised configuration, install the grill with the push-pins to obtain the 5 mm offset; if space is limited, trim the push-pins with a cutter or scissors before installation.

Recommendations

For lowest turbulence noise and best airflow performance, prefer the push-pin offset mounting when there is enough clearance. Use the included screws when a firmer mechanical connection is needed or when the available space does not allow the 5 mm offset.
