The NH-L9a-AM5 is the AM5-specific revision of Noctua's award-winning NH-L9a low-profile CPU cooler for AMD Ryzen based HTPCs and Small Form Factor (SFF) systems. At a height of only 37mm, the NH-L9a is ideal for extremely slim cases and, due to its small footprint, it provides 100% RAM and PCIe compatibility as well as easy access to near-socket connectors even on tightly packed mini-ITX motherboards. The custom-designed SecuFirm2 mounting system for the AM5 socket makes installation a breeze and, thanks to the highly optimized NF-A9x14 92mm fan that supports fully automatic speed control via PWM, the NH-L9a-AM5 runs remarkably quietly. Topped off with Noctua's renowned NT-H1 thermal compound, the NH-L9a-AM5 combines everything users have come to expect from Noctua's larger coolers into a super-compact, premium-quality package for ITX and HTPC builds with AMD AM5 processors.
