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-FG1-8 are premium-grade 80-mm fan grilles 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 5-mm offset in order to achieve even lower influx turbulence, further improved running smoothness and better airflow performance. The high-quality matte black finish and the Noctua logo at the centre make the NA-FG1 grilles a visual testament to Noctua's renowned premium quality.
