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.
