Noctua NA-IS1-12 chromax.black Sx2, Inlet Side Spacers for 120/140mm Fans (Black)

Designed to replace the fans 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. The chromax. black variant is a perfect match for black chromax or industrialPPC line fans.

Caution: As influx turbulences vary between different fans models and setups (e. g. different fan speeds, grill shapes, mesh patterns, overall flow resistance, etc. ), it is not possible to reliably predict how much of an improvement adding inlet spacers will make. While the improvements are significant in most configurations, there sometimes may be little to no improvements and, in rare situations such as with particular slit-type grills, adding spacers may even lead to undesirable results with particular fan models.
