Noctua NH-L9A-AM4 Low Profile CPU Cooler NH-L9A-AM4

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 easy 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.

New revision for Ryzen AM4 socket Since the original NH-L9a for AM2(+); AM3(+); FM1 and FM2(+) has received more than 50 awards and recommendations from international hardware websites and magazines; the new AM4 revision builds on the same proven heatsink design to provide excellent low-profile cooling performance for Ryzen CPUs and APUs.
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. Making 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-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-ITX 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-AM4 provides full compatibility with PCIe cards.
Easy access to near-socket connectors Many low-profile coolers use larger fans or heatsinks in order to achieve sufficient performance; but by protruding over the socket zone; they make it difficult or even impossible to reach near-socket connectors on tightly packed ITX motherboards. Thanks to its compact footprint; the NH-L9a-AM4 provides easy access to all connectors and components.
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-AM4 to stay remarkably quiet.
Low-Noise Adaptor Allowing the maximum speed of the NF-A9x14 PWM fan to be reduced from 2500 to 1800rpm; the included Low-Noise Adaptor (LNA) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.
Custom-designed SecuFirm2 mounting for AM4 The NH-L9a-AM4 comes with a custom-designed SecuFirm2 mounting system for the AM4 socket of AMD's Ryzen platform. Allowing the heatsink to be fixed from the back of the motherboard; it makes installation easier than ever; all while maintaining the trusted SecuFirm2 quality.
NT-H1 thermal compound Noctua's much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance; excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide; it has established itself as a benchmark for premium-quality thermal compounds.
6-year manufacturer's warranty Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans; the supplied NF-A9x14 features an MTTF rating of more than 150;000 hours and the entire NH-L9a package comes with a full 6-year manufacturer's warranty.

PLEASE NOTE - The NH-L9a-AM4 is a highly compact; quiet low-profile cooler designed for use in small form factor cases and HTPC environments. While it provides first-rate performance in its class; it is not suitable for overclocking and is only recommended for CPUs/APUs with up to 95W TDP (Thermal Design Power). Please consult Noctua's CPU compatibility list and TDP guidelines to find out whether the NH-L9a-AM4 is recommended for your CPU/APU.
