Improve cooling efficiency in compact PC builds with the Noctua NA-FD1 Fan Duct Kit. Designed specifically for Noctua NH-L9 series low-profile CPU coolers, this modular airflow duct system helps bridge the gap between the cooler and your case panel, allowing the fan to pull in fresh outside air for significantly improved thermal performance.
Ideal for Small Form Factor (SFF) systems, the EVA foam spacer design is adjustable from 5mm to 45mm in precise 1mm increments, making it compatible with many popular mini-ITX cases such as the Dan A4-SFX and Loque Ghost S1.
Easy to install and engineered with Noctua’s trusted premium quality, the NA-FD1 can help reduce CPU temperatures by up to 5°C or more, making it a must-have upgrade for compact high-performance PCs.
