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

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.
