The NA-IS1-12 Sx2 is a set of two distance spacers measuring 120mm for Noctua 120x25mm fans, designed to improve soundproofing and performance in air intake applications.

• Spacer thickness: 5mm
• Reduction of air intake turbulence, enhancing airflow and reducing noise.
• Compatible with all compatible Noctua 120x25mm fans.
• Includes suitable anti-vibration mounts and screws for easy tool-free installation.
• Ideal for applications with resistance, such as grilles and filters.
• Reduction of overall noise level and improvement of noise profile.
• The package includes 8 screws for the fan and 8 NA-AV3 anti-vibration mounts.

The black version chromax.black perfectly matches Noctua's black fans from the chromax and industrialPPC series.

The use of distance spacers can allow fans to achieve higher airflow speeds while simultaneously reducing noise emission.
