# Silence-Focused Fan Spacers Noctua Launched Two Sizes of 5mm Plastic Fan Spacers for PCs By Colin Smith | Published 2022-11-29 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/na-is1-12 References: [noctua.at](https://noctua.at/en/na-is1-12-sx2) & [noctua.at](https://noctua.at/en/products/accessories/anti-vibration)  [Noctua](https://www.trendhunter.com/trends/noctua-nf-a6x15), the company most known for its high-quality, silent PC fans, debuted the 'NA-IS1-12' and 'NA-IS1-14' inlet side spacers. These spacers sit between a PC fan and the chassis or radiator that it is mounted to, adding a small gap between the two components. This gap allows for improved airflow by pulling air through a larger surface area of the case or radiator, while also reducing volume levels by absorbing some vibrations from the fan. The NA-IS1-12 is available in Noctua's signature Brown and Beige colors, as well as in a monochrome black color. This spacer is for 120mm fans. The NA-IS1-14 on the other hand is for 140mm fans and is only available in the signature Brown and Beige Noctua colorway.
