Tuuletinsäleikkö Noctua NA-FG1-4 SX5 teräs 4 cm 32x32 mm 5 kpl

The Noctua NA-FG1-4 SX5 is a steel fan grill set for 40 mm (32×32 mm mounting pattern) fans, supplied as a pack of five. It provides sturdy protection for running fans and cables while maintaining low acoustic impact and good airflow. The grills feature a matte-black finish with the Noctua logo at the centre and include both tool-free push-pin mounts and conventional screws for flexible installation options.

Advantages

Dense, rounded steel struts offer reliable protection from accidental contact and prevent cables from being drawn into the impeller while minimising turbulence noise. The offset, round-strut design preserves high airflow and reduces acoustic penalties compared with flat or sharp-edged guards. The included push-pin system allows a 5 mm offset mounting to further lower influx turbulence and improve running smoothness, while the supplied screws provide an option for a stronger, conventional attachment. The set’s matte-black finish and central Noctua logo deliver a consistent premium appearance.

Suitable for

• Protecting 40 mm (32×32 mm) cooling fans in PCs and electronics
• Reducing risk of accidental contact with fan blades
• Applications where low acoustic impact and preserved airflow are required
• Tool-free or screw-mounted installations

Key specifications

• Model: Noctua NA-FG1-4 Sx5
• Type: Steel fan grill
• Fan size compatibility: 40 mm (32×32 mm mounting pattern)
• Pack size: 5 pieces

How to use

Push the supplied rubber plugs into the fan’s mounting holes, position the grill over the fan, and secure it with the plastic push-pins by pressing them into place. For a conventional attachment, use the included coated screws to fasten the grill to the fan or chassis. If the 5 mm offset from the push-pins does not fit in your installation space, the pins can be shortened with a cutter or scissors to allow flush mounting.

Recommendations

For best acoustic and airflow results, install the grills using the push-pins to create the 5 mm offset; use the screws where extra mechanical strength or a flush fit is required.
