Product Description

Manufacture # Noctua | Model # NA-FD1


The NA-FD1 fan duct kit makes it possible to significantly improve the performance of Noctua NH-L9i and NH-L9a series CPU coolers in Small Form Factor (SFF) environments where there is a gap of 5mm or more (up to 45mm) between the cooler and a perforated top or side panel. Bridging this gap, the duct prevents the cooler from taking in hot air from the interior and enables it to draw in fresh air from the outside through the perforated panel, which can, depending on the setup, improve CPU temperatures by as much as 5°C or more. As the duct is assembled from EVA foam spacers of different thickness, it is fully modular and can be adjusted in 1mm increments from 5mm to 45mm height in order to fit various different cases and configurations.



  • By enabling the NH-L9 cooler to draw in fresh air from the outside instead of hot interior air, adding the NA-FD1 can lead to huge performance gains of up to 5°C and more. 
  • The NA-FD1 is fully compatible with all variations of the NH-L9i (NH-L9i, NH-L9i, NH-L9i-17xx, NH-L9i-17xx and NH-L9a (NH-L9a, NH-L9a-AM4, NH-L9a-AM4 series. It is not compatible with the NH-L9x65, NH-L9x65 SE-AM4 or other coolers.
  • With the NA-FD1, the NH-L9’s fan has at least 5mm (and up to 45mm) of breathing space, which yields a smoother sound signature compared to taller coolers that may struggle with intake noise issues due to low clearance.
  • Consisting of 7 foam spacers from 10 to 3mm thickness, the NA-FD1 can be adjusted from 5mm to 45mm in 1mm increments.
  • The NA-FD1 set consists of 7 Ethylene-Vinyl Acetate (EVA) foam spacers with different thicknesses (2x 10, 7, 6, 5, 4, 3mm) that can be stacked to bridge gaps of different sizes.
