Product Description
The NH-L9a-AM4 is the latest, AM4-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 AM4 socket makes installation child’s play and, thanks to the highly optimised NF-A9x14 92mm fan that supports fully automatic speed control via PWM, the NH-L9a-AM4 runs remarkably quietly. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9a-AM4 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 Ryzen CPUs or APUs.
37mm low profileDue 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 compatibilityThe NH-L9a-AM4 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 on mini-ITXSome 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-AM4 provides full compatibility with PCIe cards. | NF-A9x14 PWM premium fanThe 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-AM4 to stay remarkably quiet. |
