NA-FG1-4

Available in sets of 2 (Sx2) or 5 (Sx5) including screws and a tool-free mounting system that can help to reduce both turbulence noise and performance losses, Noctua’s NA-FG1-4 are premium grade 40mm fan grills for the highest demands in acoustic optimisation and ease of installation. Thanks to an offset design with round struts, the NA-FG1 guards offer excellent protection with minimal impact on the fan’s acoustics and flow rate. The included tool-free push-pin mounting system not only makes installation a breeze, even if the fans are already installed in a PC system, it also introduces an additional 5mm offset in order to achieve even lower influx turbulence, further improved running smoothness and better airflow performance. Last but not least, the high-quality matte black finish and the Noctua logo at the centre make the NA-FG1 grills a visual testament to Noctua’s renowned premium quality.

Improvements from offset mounting

Details

Reliable protection

Thanks to their densely spaced, sturdy steel ribs, Noctua’s NA-FG1 series fan grills offer excellent protection and reliably prevent you from accidentally touching the running fan or cables from being pushed into the impeller.

Excellent acoustics, high airflow

While flat fan grills or fan guards with sharp edges can create unpleasant, high-pitched turbulence noises and often also reduce airflow significantly, Noctua’s NA-FG1 units use an offset design with rounded struts in order to ensure that the impact on fan acoustics and performance is as low as possible.

Elegant, matte-black design

With their sturdy steel construction, elegant matte-black finish and Noctua logo at the centre, the NA-FG1 series fan guards are visual testament to Noctua’s renowned premium quality and a great compliment to its iconic fans.

Tool-free push-pin mounting

The NA-FG1 sets include a proprietary push-pin mounting system that makes installing the grills a breeze: Push the rubber plugs into the fan’s mounting holes, put on the grill and fix it by pushing in the plastic pins. No screwdriver or other tools required!

Offset mounting for extra quietness and better performance

The supplied push-pins make it possible to install the grills 5mm offset from the fan. This extra spacing helps to further improve acoustics and airflow by reducing influx turbulence. In practice, this means that fans can run noticeably quieter and more efficient when the grills are fixed using the push-pins instead of screws. In case there isn’t enough space for the 5mm offset, the push-pins can be shortened using a cutter knife or scissors.

Mounting screws included

In addition to the tool-free push-pin mounts, Noctua NA-FG1 grills also include regular fan screws. Thanks to a high-quality black coating, the screws nicely complement the matte black finish of the grills and can either be used for applications that require extra-strong attachment, or for installing the fans themselves.

Sets of 2 and 5

The NA-FG1-4 are available in sets of 2 (NA-FG1-4 Sx2) and 5 (NA-FG1-4 Sx5). In addition to the fan grills, the kits include standard fan screws as well as Noctua’s unique, offset push-pin mounts for tool-free, acoustically optimised installation (one set of screws and one set of push-pins for each fan grill).
