❄️ Elevate your SFF cooling game — because every degree counts!
The Noctua NA-FD1 Fan Duct Kit is a modular EVA foam spacer system designed to bridge gaps between NH-L9i/NH-L9a CPU coolers and perforated case panels. Adjustable from 5 to 45mm in 1mm increments, it channels fresh outside air directly to the cooler, improving CPU temperatures by up to 5°C while reducing fan intake noise. Ideal for popular Small Form Factor cases like Dan A4-SFX and Louqe Ghost S1, it offers easy installation and broad compatibility with NH-L9 series coolers, making it a smart, flexible upgrade for compact, high-performance PC builds.

Noticeable performance upgrade.
Works great to squeeze some extra performance out for the cooler when installed in slim and small cases. Used in a Fractal Node 202 and noticed an immediate performance upgrade. Fans can run slower and quieter and still deliver acceptable temperatures.

Gamechanger
Gerade in kleinen ITX Gehäuse ist der Bausatz Gold Wert, vorher überhitzungsprobleme, weil der Kühler nur warme Luft gesaugt hat und mit dem Duct Kit sehr schöne Temperaturen und vorallem ein Stabiles System!

Top als het past
Als het in je case past, dan echt een aanrader. Kost vrij weinig en maakt een aanzienlijk verschil.
