Genuine Noctua NA-FD1 fan duct kit for NH-L9i and NH-L9a series CPU coolers, sold as an open-box incomplete kit. This is a great option for SFF / Mini-ITX builders who need a replacement NA-FD1 set at a lower cost and do not need the full retail package.
The NA-FD1 is designed to bridge the gap between a Noctua NH-L9 cooler and a perforated top or side panel, helping the cooler draw in fresh outside air instead of warmer air from inside the case. Noctua states this can improve temperatures by up to 5°C or more depending on the setup, and the full kit is adjustable for gaps from 5mm to 45mm using modular EVA foam spacers.
This listing is ideal for:
- Replacing a lost or damaged Noctua NA-FD1
- Completing an NH-L9i / NH-L9a SFF build
- Improving cooling in Mini-ITX / SFF cases
- Buyers who want an original Noctua accessory without paying full retail for a sealed kit
Important condition note
This kit is missing the 6mm foam spacer. The original NA-FD1 scope of delivery from Noctua is 7 foam spacers total: 10mm (2x), 7mm, 6mm, 5mm, 4mm, 3mm, plus 16 plastic tubes and 4 steel bolts. This sale does not include the 6mm spacer, so it is not a complete retail kit.
