NA-FG1-5 Sx2

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.

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.

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!

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.
