## Description

Noctua NA-FD1, CPU Cooler Fan Duct Kit for SFF PC Cases | NH-L9i, NH-L9a Series Compatible and 92mm Fans, Improves Cooling Boosts Performance, Set of: 2x10mm, 7mm, 6mm, 5mm, 4mm, 3mm : desertcart.co.uk: DIY & Tools

Review: Great results - Had Jonsbo NV10 case and with Noctua CPU cooler left slightly less than 5mm clearance. Took a chance on this kit. You could get away with just fitting 5mm spacer without tubes but cut tubes slightly less than securing "bolts". Push on lid of case fitted but only just. The results were better than I thought. Noise levels dropped dramatically and Fan speed dropped from around 1800rpm(idle) to 1600rpm with mid load. CPU temps dropped by about 15°
Review: Phenomenal for tiny cases - Phenomenal product if you’re using a very small PC case. My case is a sandwich ITX that’s sub 7ltrs and it dropped the temps of my 7600 from high 80’s to low 70’s.

## Features

- Bridges the gap between the fan and perforated case panels in order to enable the cooler to draw in fresh air from the outside for improved cooling performance (up to 5°C and more)
- Modular system made from EVA foam spacers, adjustable from 5 to 45mm in 1mm increments, ideal for popular SFF cases (e.g. Dan A4-SFX, Loque Ghost S1)

## Questions & Answers

**Q: What size are these.?  140 mm 120 mm etc?**
A: They are for 92 mm fans -- like on the NH-9Li, NH-9La, or NH-9x65/

**Q: Is there a model for 120mm fans?**
A: The Fan Duct Kit was specifically for the NH-L9 CPU Coolers which are low profile.  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)

### ⭐⭐⭐⭐⭐ Phenomenal for tiny cases
*by P***. on 23 January 2025*

Phenomenal product if you’re using a very small PC case. My case is a sandwich ITX that’s sub 7ltrs and it dropped the temps of my 7600 from high 80’s to low 70’s.

### ⭐⭐⭐⭐⭐ Super easy to install, seems to work well!
*by T***R on 12 April 2022*

I didn't follow the installation instructions to the letter - i.e. measuring the distance between the cooler and the side of the case to get a precise fit; just did it by eye instead -- and it was as snug without pushing on the side plate too much. Lots of different sized pieces of foam will definitely help with re-use with other cases, if that should come to pass.
