Anti-vibration gasket Noctua NA-SAVG1 Rubber Black 3 pcs

The Noctua NA-SAVG1 chromax.black is a set of three black anti-vibration gaskets designed for use with compatible Noctua 120x25mm fans on water-cooling radiators or other applications where a tighter seal between fan and surface improves cooling efficiency. Made from extra-soft yet tear-resistant silicone rubber, these gaskets dampen minute vibrations and reduce air loss between fan and radiator, helping to optimise airflow and thermal performance.

Advantages

The NA-SAVG1 gaskets provide improved sealing between fan and radiator, which can reduce air bypass and slightly improve cooling effectiveness. Their soft, tear-proof silicone construction reduces transmitted vibrations and helps lower noise caused by mechanical coupling. The set comes in an all-black chromax.black finish that matches Noctua’s black fan lines.

Suitable for

• 120x25mm Noctua fans (e.g., NF-A12x25, NF-F12, NF-S12A, NF-P12 redux)
• Water-cooling radiators (240 mm and 360 mm configurations)
• PC builds where improved fan-to-radiator sealing and vibration damping are desired

Key specifications

• Contents: 3 anti-vibration gaskets
• Compatibility: designed for 120x25mm Noctua fans; not compatible with 120x15mm NF-A12x15 series
• Material: extra-soft, tear-resistant silicone rubber
• Finish: chromax.black (all black)
• MPN: NA-SAVG1 ch.bk, EAN: 9010018201154

How to use

Fit the gasket around the fan frame so that it sits between the fan and the radiator or mounting surface, aligning the gasket with the fan’s screw holes. The gaskets leave the screw holes accessible, allowing installation with standard fan screws, radiator screws or anti-vibration mounts (e.g., Noctua NA-AV1/NA-AV2/NA-AV3/NA-AV4). Use one gasket per fan; the set of three is suitable for installing up to three 120x25mm fans on a radiator.

Recommendations

Use the NA-SAVG1 gaskets when you want to minimise air leakage between fan and radiator and reduce mechanical vibration. Ensure compatibility with 120x25mm fans and avoid use with 120x15mm models. For optimal results on 360 mm radiators, install three gaskets with three matching 120x25mm fans.
