Grelha para ventoinha Noctua NA-FG1-8 SX2 aço 8 cm 71,5x71,5 mm

The Noctua NA-FG1-8 SX2 is a steel fan grill designed for 8 cm (71.5 x 71.5 mm mounting pattern) fans and supplied in a set of two. It provides sturdy protection for running fans while minimising impact on airflow and acoustics. The grills feature rounded, offset struts, a matte-black finish and a central Noctua logo. The set includes both screws and a tool-free push-pin mounting system that allows optional 5 mm offset installation to reduce influx turbulence and improve running smoothness.

Advantages

Dense, sturdy steel ribs reliably prevent accidental contact with the impeller and stop cables from being drawn into the fan. The offset design with rounded struts reduces turbulence noise and limits airflow loss compared to flat or sharply edged guards. The included push-pin system enables tool-free installation and an additional 5 mm spacing for improved acoustics and airflow, while the supplied coated screws provide a secure alternative attachment. The matte-black finish and central logo offer a consistent visual match with Noctua components.

Suitable for

• 8 cm (80 mm) case fans with 71.5 x 71.5 mm mounting hole pattern
• Systems where quieter fan operation and reduced turbulence are desired
• Installations requiring tool-free mounting or optional offset spacing
• Applications needing reliable finger and cable protection for fans

Key specifications

• Material: steel
• Finish: matte black
• Compatibility: 80 mm (8 cm) fans, mounting hole pattern 71.5 x 71.5 mm
• Set contents: 2 fan grills, screws and push-pin mounts (one set per grill)
• Optional offset: 5 mm when using push-pin mounts

How to use

Push the supplied rubber plugs into the fan’s mounting holes, position the grill over the fan and fix it by inserting the plastic push-pins until they lock. For a more secure or non-offset installation, use the supplied screws to attach the grill to the fan or chassis. If the 5 mm offset created by the push-pins does not fit your installation space, the push-pins can be shortened with a cutter or scissors before insertion.

Recommendations

For lowest turbulence and best acoustic performance, mount the grills using the push-pin system to achieve the 5 mm offset where space permits; use the coated screws for situations that require stronger mechanical attachment or when offset mounting is not possible.
