Haven't seen a 120mm version. The Fan Duct works very well on the NH-L9 coolers, sealing out warm air from inside the case and only allowing the cooler outside air in. I have a tiny AMD build in a 4 liter case, and the Duct kit helps keep CPU Temps in the 95 degrees (39C) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Spettacularis *by G***A on 18 September 2023* Noctua Spettacularis la terza foto non ha bisogno di commenti…punteggio più basso senza Noctua FOAM, punteggio più alto con Noctua FOAM ### ⭐⭐⭐⭐⭐ Funciona de maravilla *by R***A on 23 August 2026* No fueron utilizados en el cooler de Noctua para el que fueron hechos, pero con los accesorios que trae se montó sin problemas, redujo mi temperatura del cpu (mini itx) en 5 grados celsius ### ⭐⭐⭐⭐⭐ Noticeable performance upgrade. *by T***S on 27 December 2024* 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. ## Frequently Bought Together - Noctua NA-FD1, Fan Duct Kit for NH-L9i and NH-L9a Series CPU Coolers (Black) - Noctua NF-A9x14 HS-PWM chromax.Black.swap, Premium Quiet Slim Fan, 4-Pin (92x14mm, Black) - Thermalright AXP90 X47 Full Low Profile CPU Cooler, 47mm Height, with TL-9015R Slim PWM CPU Fan,Pure Copper Version, Computer ITX Heatsink Cooler, for AMD:AM4 AM5/Intel 1150/1151/1200/1700 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/386453296-noctua-na-fd1-fan-duct-kit-for-nh-l9i-nh](https://www.desertcart.hr/products/386453296-noctua-na-fd1-fan-duct-kit-for-nh-l9i-nh) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-23*
