Noctua NA-IS1-12-SX2 Inlet Side Spacers
The NA-IS1-12 Sx2 is a set of two 5mm thick intake side spacer frames for Noctua 120x25mm 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-IS1-12 are compatible with all current square-frame Noctua 120x25mm fans and extremely straightforward to install: For case fan applications, either the supplied self-tapping screws or the included NA-AV3 anti-vibration mounts can be used to sandwich the spacer between the fan and the case panel.
For radiator mounting, both M3 and UNC 6-32 screws are supplied. In sum, the NA-IS1-12 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.
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.
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.
Improving Suction Acoustics
Suction applications where fans draw air through obstacles such as grills or perforated panels are notoriously challenging acoustically due to the turbulences caused by these obstacles. Introducing a 5mm off-set between the fan and the obstacle, the NA-IS1 spacers can reduce these turbulences, which often improves noise levels and/or noise profiles significantly.
Compatible with All Current Noctua 120x25mm Fans
Replacing the fan’s stock NA-AVP1 anti-vibration pads, the NA-IS1-12 are compatible with all current Noctua square-frame 120x25mm fans such as the popular NF-A12x25, NF-F12, NF-P12 redux or NF-S12A series. The slim NF-A12x15 or fans from other manufacturers are not supported.
Anti-vibration Mounts and Fan Screws
For use with case intake fans, the NA-IS1-12 Sx2 contains eight long self-tapping fan screws and eight NA-AV3 silicone anti-vibration mounts for tool-free, vibration-proof installation. Both the screws and the anti-vibration mounts simply go through the holes in the spacer and attach to the fan, sandwiching the spacer between the fan and the case.
Features
• Helps achieve higher airflow and lower noise.
• Offsets the fans by 5mm to reduce fan turbulence.
• Supplied with eight anti-vibration mounts.
