Noctua, a well-known cooling system manufacturer, recently released a new series of products for enthusiasts that included fan grills! While for sure didn't expect this, Noctua is very proud of this new lineup of products and today we will take a look at what is all this fuss about.

The Noctua NA-FG1 series of fan grills for 40, 50, 60, 70, 80, 92, 120, 140, and 200mm fans. Available in sets of 2 (Sx2) or 5 (Sx5) including screws and a tool-free mounting system can help to reduce turbulence and thereby improve both airflow performance and noise levels.

Noctua explains that “Fan grills may seem like a trivial accessory, but many available solutions can seriously hamper your fans’ acoustics and performance, so we decided to offer our own selection of grills, Our NA-FG1 use a proven, highly efficient design and top it off with a convenient tool-free mounting system that introduces an extra offset and can thereby help to improve both airflow and noise levels.”

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 included tool-free push-pin mounting system not only makes installation a breeze, even if the fans are already installed in a PC system, but it also introduces an additional 5mm offset in order to achieve even lower influx turbulence, further improving running smoothness and better airflow performance.

In Noctua’s tests, the additional offset allowed for a reduction of the grills’ average impact on airflow performance from 3 to 2% and the average impact on noise levels from 1.2dB(A) to 0.6dB(A).

The NA-FG1 are available in sets of 2 (Sx2) and 5 (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 optimized installation (one set of screws and one set of push-pins for each fan grill).

Below we gathered a table including links for all released products and their retail prices. As we can see up to 90mm prices are the same, also from 120 up to 200mm also the price is constant.
