Fan grill Noctua NA-FG1-6 SX2 Steel 6 cm 50x50 mm 2 pcs

The Noctua NA-FG1-6 SX2 steel fan grill is engineered for 60 mm (6 cm) fans with a 50 x 50 mm mounting hole pattern and supplied as a pack of two. Constructed from sturdy steel with a matte-black finish and a central Noctua logo, this grill protects fan blades and internal cables while maintaining high airflow. An offset design with rounded struts minimises turbulence and acoustic impact, and the set includes both conventional screws and a tool-free push-pin mounting system that provides an additional 5 mm offset for improved smoothness and reduced inlet turbulence.

Advantages

The dense, robust steel ribs reliably prevent accidental contact with the rotating impeller and stop cables from being drawn into the fan. The offset strut geometry and rounded profile reduce high-pitched turbulence and preserve airflow, so cooling performance remains close to that of an unprotected fan. The included push-pin mounts enable fast, tool-free installation and introduce a controlled offset that lowers noise and increases effective airflow. Matte-black coating and central branding provide a uniform, unobtrusive appearance suitable for visible system builds.

Suitable for

• Protecting 60 mm case fans in desktop PCs and small form factor systems
• Reducing accidental contact with fan blades in workstations or public-access systems
• Acoustic optimisation where reduced inlet turbulence is required
• Upgrading aesthetic appearance of visible fan installations

Key specifications

• Material: steel with matte-black finish
• Compatible fan size: 60 mm (6 cm)
• Mounting hole spacing: 50 x 50 mm
• Pack contents: two fan grills per set, screws and tool-free push-pin mounts
• Offset mounting capability: 5 mm with supplied push-pins (push-pins can be shortened if clearance is limited)
• Design: offset struts with rounded profile to minimise turbulence

How to use

For push-pin installation, insert the supplied rubber plugs into the fan’s mounting holes, position the grill over the fan, then push the plastic pins through the grill into the plugs until they lock. This creates a 5 mm offset that reduces inlet turbulence and can improve acoustic behaviour and airflow. If clearance does not allow the offset, the push-pins can be shortened or the provided screws can be used instead. When using screws, align the grill to the fan mounting holes and secure it with the included black-coated screws for a firm attachment.

Recommendations

Use the push-pin mounting method when space permits to prioritise lower turbulence and quieter operation; switch to screws for applications that require maximum mechanical retention. If limited clearance prevents the full offset, carefully shorten the push-pins with a cutter or scissors to achieve the best fit while maintaining protection and airflow.
