Product information

Description

The NA-IS1-12 Sx2 is a set of two 5 mm intake side spacer frames for Noctua 120x25 mm square-frame fans. They are designed to offset the fan from grills, perforated plates, mesh panels, filters or radiators in suction (pull) applications, reducing influx turbulence to improve airflow behavior and acoustic performance. The kit replaces the stock NA-AVP1 anti-vibration pads and is compatible with current Noctua 120x25 mm square-frame models. The set includes spacers, anti-vibration mounts, long self-tapping fan screws and radiator screws in both M3 and UNC 6-32 threads for flexible installation options.

Advantages

The 5 mm offset created by the NA-IS1 spacers reduces turbulence caused by obstacles in front of intake fans, which can result in lower noise levels and a smoother noise profile. By reducing inlet disturbances, the spacers can also allow fans to operate more efficiently, sometimes delivering higher airflow and reduced noise emissions simultaneously. The kit is straightforward to install and replaces the fan’s original anti-vibration pads while providing both case- and radiator-mounting hardware.

Suitable for

  • 120x25 mm Noctua square-frame intake fans (e.g., NF-A12x25, NF-F12, NF-P12 redux, NF-S12A series)
  • Front case intake applications with grills, mesh or perforated panels
  • 240 mm radiators or other radiator mounts in intake (pull) configuration

Key specifications

  • Set: NA-IS1-12 Sx2 (two 5 mm spacer frames)
  • Compatibility: Noctua 120x25 mm square-frame fans (not compatible with slim 120x15 mm models)
  • Included hardware: 8 long self-tapping fan screws, 8 NA-AV3 silicone anti-vibration mounts, 8 M3 radiator screws (35 mm), 8 UNC 6-32 radiator screws (35 mm)
  • Material / color: brown / light brown (matches Noctua aesthetic)

How to use

Replace the fan’s stock NA-AVP1 anti-vibration pads with the NA-IS1 spacer frames. For case intake installation, position the spacer between the fan and the case panel and secure using the supplied self-tapping screws or the NA-AV3 anti-vibration mounts, which sandwich the spacer to the fan. For radiator mounting in intake configuration, use the supplied 35 mm radiator screws in the thread type required by the radiator (M3 or UNC 6-32). Ensure screws are tightened securely but avoid overtightening.

Usage recommendations

Use the NA-IS1-12 spacers specifically for suction (pull) applications where fans draw air through obstacles. Do not use with slim 120x15 mm fans or non-square-frame models. Choose the correct radiator screw thread (M3 or UNC 6-32) for your radiator and check compatibility with your fan model before installation.
