    Noctua NA-IS1-14 chromax.black Sx2, Inlet Side Spacers for 140mm Fans (Black)

    • Introducing a 5mm offset, NA-IS1-14 14cm inlet spacers can reduce influx turbulences in suction type applications where fans draw air through perforated panels or other obstacles in close proximity; Simple but effective: In many situations, reducing influx turbulence can lead to significantly improved airflow performance as well as lower noise levels and more pleasant sound signatures; Ideal for PC case intake fans, pull fans on water cooling radiators or other situations where fans draw air through grills, perforated panels, punctuated sheets, mesh structures, filters, etc.; Compatible with all current Noctua 140x25mm fans such as the popular NF-A14 or NF-P14s redux, not compatible with fans from other manufacturers; Sx2 set includes two inlet spacers, 8x NA-AV3 anti-vibration mounts, 8x screws for case fan installation, 8x screws for radiators with M3 threads and 8x screws for radiators with UNC 6-32 threads

    The NA-IS1-14 Sx2 is a set of two 5mm thick intake side spacer frames for Noctua 140x25mm fans that can help to improve both acoustics and performance in suction or "pull" type applications where the fan draws air through obstacles such as grills, perforated plates, mesh panels, filters or radiators. By offsetting the fan from the obstacle, the NA-IS1 inlet spacer reduces influx turbulences, which can, depending on the application and fan model, not only improve airflow but also significantly reduce overall noise levels and make the fan sound more pleasant to the ear.

    Designed to replace the fan's stock NA-AVP1 anti-vibration pads, the NA-IS1-14 are compatible with all current square-frame Noctua 140x25mm fans and extremely straightforward to install. In sum, the NA-IS1-14 Sx2 set is a simple yet highly effective fine-tuning measure for suction type applications where a reduction of influx turbulence can lead to improved airflow and acoustics. More airflow, less noise Reducing influx turbulences doesn't only improve acoustics, it also helps fans to operate more efficiently from an airflow performance point of view. In many suction-type applications, using inlet spacers can therefore enable fans to achieve both higher flow rates and lower noise emissions.
