Noctua NA-SFMA1 120mm 2-pack Mounting Kits, Black

The Noctua NA-SFMA1 is a set of two adapters designed to mount 120 mm fans onto 140 mm water-cooling radiators. Each frame is made from polybutylene terephthalate (PBT), a durable material suited for high-performance cooling setups. This kit allows you to use the specific acoustic and airflow characteristics of 120 mm fans in systems originally designed for 140 mm mounting points. These adapters resolve compatibility issues in custom liquid cooling loops and chassis fan placements without requiring permanent modifications.

The adapters are designed for 120x25 mm Noctua fan models, including the NF-A12x25 and NF-F12 series. The package includes eight NA-AV4 anti-vibration mounts, which decouple the fan from the radiator to minimise noise caused by vibration. Standard mounting screws are also provided to secure the frames to the radiator or case. This kit is a practical solution for builders who want to standardise fan sizes across their system without replacing existing 140 mm radiators. The 2-pack allows for the conversion of dual-fan radiator setups with a single purchase.

• Compatible with NF-P12 redux, NF-S12A, and industrialPPC variants of Noctua 120 mm fans.
• Total kit weight of 170 g; the lightweight design avoids adding strain to radiator mounts.
• Frames match the 140 mm footprint of standard 140 mm fans.
• Polybutylene terephthalate construction withstands the temperatures typical in liquid cooling environments.
• Includes mounting hardware for a straightforward, modular installation process.
