The NH-L9a-AM5 chromax.black is an all-black version of Noctua’s award-winning NH-L9a-AM5 low-profile quiet CPU cooler for AMD AM5 based HTPCs and Small Form Factor (SFF) builds. Thanks to the same proven heatsink design and NF-A9x14 PWM fan, it stays true to the NH-L9a-AM5’s successful formula of fusing a height of only 37mm with strong performance and excellent quietness of operation, as well as 100% RAM and PCIe compatibility. At the same time, the chromax.black version with its black fan and black coated heatsink combines these assets with a sleek stealth look. Topped off with the renowned SecuFirm2™ low-profile mounting system for AMD AM5, Noctua’s enthusiast-grade NT-H1 thermal compound and a full 6-year manufacturer’s warranty, the NH-L9a-AM5 chromax.black is a premium choice for customers who seek an ultra-compact heatsink that looks just as great as it cools.



Key features

37mm low profile

Due to the slim 23mm heatsink and the NF-A9x14 low-profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers.

100% RAM compatibility

The NH-L9a-AM5 has a compact footprint that fully complies with the socket keep-out zones specified by AMD. This means that neither the heatsink nor the fan overhang the RAM, so the cooler provides easy access to the slots and is fully compatible with tall memory modules.

100% compatibility with PCIe cards

Some AMD-based mini-ITX motherboards have the PCIe slot located close to the CPU socket zone. While larger coolers that exceed this zone may block the PCIe slot, the compact-sized NH-L9a-AM5 provides full compatibility with PCIe cards.

NF-A9x14 PWM premium fan

The highly optimised, award-winning NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9a to stay remarkably quiet.
