Premium 140mm fan guards for quiet builds

Noctua's NA-FG1-14 Sx2 set provides two matte-black metal grills designed for 140mm fans. They use round struts and an offset pattern to protect spinning blades while keeping airflow restriction and turbulence noise to a minimum. The package includes eight standard screws plus eight tool-free push-pin mounts that add an extra 5mm stand-off for smoother intake flow. Builders who want reliable finger and cable protection without sacrificing acoustic performance will appreciate the premium fit and finish.

Suited for noise-focused PCs and exposed-fan setups

These grills are ideal for enthusiasts who run 140mm fans in open panels, desk-mounted rigs, 3D printers or home ventilation projects where safety and low noise matter. They are not intended for builders using smaller fan sizes, for cases that already ship integrated fan filters, or for anyone needing a coloured accent other than the supplied matte black. The two-pack also falls short for full-tower builds that require more than two guarded positions.

Tool-free pins and offset mounting simplify

The push-pin mounts let you secure or remove grills in seconds without tools, even when fans are already fixed in a chassis, while the built-in 5mm offset reduces inflow turbulence for quieter operation. Standard screws remain an option for permanent installations or thicker panels. No software, lighting controllers or additional accessories are bundled; the package contains only the two grills, screws and push-pins.

Questions about this item

Will these 140mm grills fit the 140mm fans I already own?

Yes, the grills are made for 140mm fans and the set includes both traditional screws and tool-free push-pin mounts for standard fan frames.

Does the 5mm offset from the push-pin mounts change clearance next to my existing side-panel or radiator?

The push-pin system adds a 5mm stand-off, so allow that extra depth when measuring space beside panels, radiators or cable runs.

How can I confirm the offset mounting is reducing turbulence after I install the pair?

Listen for smoother airflow noise and check that fan speeds hold steady under load compared with the same fans running without the grills.
