Fan grill Noctua NA-FG1-9 SX5 Steel 9.2 cm 5 pcs

The Noctua NA-FG1-9 SX5 is a steel fan grill designed for 92 mm (9.2 cm) fans. Supplied as a set of five, the pack includes fan screws and Noctua's tool-free push-pin mounting system that allows an offset installation to reduce turbulence noise and minimise performance losses while providing reliable protection for the fan blades.

Advantages

Constructed from sturdy steel with a matte-black finish and a central Noctua logo, the NA-FG1 grills combine durable protection with low acoustic impact. The offset design with rounded struts minimises airflow disruption and high-pitched turbulence, while the included push-pin system enables a 5 mm offset mounting for improved running smoothness and airflow. Standard black-coated screws are also included for stronger attachment when required.

Suitable for

• Protection of 92 mm PC fans against accidental contact and cable ingress
• Acoustic optimisation of cooling setups where lower turbulence noise is desired
• Systems requiring both tool-free installation and the option of screw mounting
• Upgrading visual appearance of fans with a matte-black grill

How to use

For tool-free installation, insert the supplied rubber plugs into the fan’s mounting holes, position the grill and press the plastic push-pins through until secured. To benefit from reduced inlet turbulence and improved acoustics, use the push-pins to mount the grill with the 5 mm offset; if there is insufficient clearance, the push-pins can be shortened with a cutter or scissors. Alternatively, use the included black-coated screws to fasten the grill directly for a more rigid attachment or when offset mounting is not possible.

Recommendations

If you prioritise the quietest possible operation, mount the grills using the push-pins to achieve the 5 mm offset. Ensure the push-pins are fully engaged and check clearance before finalising installation; trim the pins only if necessary and avoid damaging the fan housing.
