Grelha para ventoinha Noctua NA-FG1-4 SX2 aço 4 cm 32x32 mm

The Noctua NA-FG1-4 Sx2 is a steel fan grill designed for 40 mm (32 x 32 mm mounting) fans, supplied as a set of two. It provides reliable protection for the fan and cables while preserving acoustic performance and airflow, and includes both conventional screws and a tool-free push-pin mounting system that allows an optional 5 mm offset for reduced turbulence.

Advantages

Constructed from sturdy steel with densely spaced rounded struts, the NA-FG1-4 grill protects fingers and wiring without significantly affecting fan noise or flow. The tool-free push-pin system enables quick installation and can position the grill 5 mm away from the fan for reduced inlet turbulence and improved running smoothness. The matte-black finish and centre Noctua logo ensure a consistent, high-quality appearance that matches Noctua fans.

Suitable for

• Protection of 40 mm fans with 32 x 32 mm mounting holes
• Quiet PC builds where inlet turbulence should be minimised
• Systems that require tool-free or quick grill installation
• Aesthetic upgrades to Noctua or other matte-black fan assemblies

How to use

For screw mounting, align the grill with the fan's 32 x 32 mm mounting holes and secure it using the supplied black-coated screws. For tool-free mounting, insert the rubber plugs into the fan’s mounting holes, place the grill over the plugs and push the plastic pins through to lock the grill in place. If the optional 5 mm offset cannot be accommodated, the push-pins can be shortened with a cutter or scissors.

Recommendations

Use the push-pin mounting when possible to gain the acoustic and airflow benefits of the 5 mm offset; use screws when a stronger mechanical attachment is required or when there is insufficient clearance for the offset.
