Noctua is a well respected manufacturer in the highly competitive CPU cooler space, offering products optimized for high efficiency and low-noise. Their latest release for AMD Ryzen processors offer good stock performance at minimal noise levels. The cooler's minimalistic dimensions also ensures broad compatibility with AM4-based systems. Unlike other members of the Noctua cooler line, the L9a-AM4 uses a proprietary mounting system, not the standard SecuFirm2™ mounting mechanism. With an MSRP of $39.99, the NH-L9a-AM4 comes at a premium price for its performance goals.

The NH-L9a-AM4 CPU cooler is single radiator cooler placed in a horizontal orientation with a single included fan. The radiator's horizontal orientation gives the cooler a lower height in comparison to a cooler with the traditional vertical radiators while maintaining equivalent cooling performance. In typical Noctua fashion, the NH-L9a-AM4 combines a copper base plate and heat pipes with aluminum finned cooling towers for an optimal hybrid cooling solution. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion.
