Noctua NH-L9a-AM4 37mm low-profile CPU cooler for AMD Ryzen
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 optimized 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.
Caution: The NH-L9a-AM4 is a highly-compact low-profile quiet 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 only recommended for CPUs/APUs with up to 95W TDP (Thermal Design Power). Please consult the TDP guidelines to find out whether the NH-L9a-AM4 is recommended for your CPU/APU.
Noctua NH-L9a-AM4 Features:
New revision for Ryzen’s 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, which makes 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 92x114mm footprint that complies to the 96x114mm keep-out zone specified by AMD. This means that it doesn’t overhang the RAM slots, so it’s fully compatible with tall memory modules.
100% Compatibility with PCIe Cards on Mini-ITX
Some AMD based mini-ITX mainboards have the PCIe slot sitting close to the 96x114mm socket zone. While larger coolers that exceed this zone may block the PCIe slot, the 92x114mm 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 optimized 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 to stay remarkably quiet.
Allowing to reduce the maximum speed of the NF-A9x14 fan from 2500 to 1800rpm, the included Low-Noise Adaptor (L.N.A.) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.
Custom-designed SecuFirm2™ mounting for AM4
The NH-L9a bundles a custom-designed SecuFirm2™ mounting system for AM2(+)/AM3(+)/FM1/FM2 that offers extended compatibility with mini-ITX boards and makes installation easier than ever, all while maintaining the trusted SecuFirm2™ quality.
NT-H1 Thermal Compound
Noctua’s much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.
6 Years Manufacturer's Warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9x14 features an MTBF rating of more than 150,000 hours and the entire NH-L9a package comes with a full 6 years manufacturer's warranty.
