Noctua NH-L9a-AM4 chromax.black CPU Cooler NH-L9A-AM4-CH-BK

The NH-L9a-AM4 chromax.black is an all-black version of Noctua's award-winning NH-L9a-AM4 low-profile quiet CPU cooler for AMD Ryzen 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-AM4'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. Topped off with the renowned SecuFirm2 low-profile mounting system for AMD AM4; Noctua's enthusiast-grade NT-H1 thermal compound and a full 6-year manufacturer's warranty; the NH-L9a-AM4 chromax.black is a premium choice for customers who seek an ultra-compact heatsink that looks just as great as it cools.

Award-winning NH-L9a-AM4 cooler Tens of thousands of enthusiast users all over the world swear by the NH-L9a-AM4's quality and performance. Recommended by more than 50 international hardware websites and magazines; it is renowned as being one of the best low-profile coolers for AMD Ryzen CPUs and APUs.
chromax.black design The NH-L9a-AM4 chromax.black is black from head to toe: Featuring a black coated heatsink; a black fan with black anti-vibration pads; black fan screws and black mounting parts; it's right at home in all-black builds and easy to integrate with other colour schemes.
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.0% 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.0% 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 with suitable CPUs/APUs that only create smaller heat loads.
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.
Soldered interface between heatpipes and fins With many heatsinks; the fins are press-fitted to the heatpipes. Due to the different thermal expansion coefficients of copper and aluminium; this fit can loosen over years of thermal cycling; which may lead to reduced performance. By contrast; the NH-L9a's fins are soldered to the heatpipes in order to guarantee a superior thermal interface that doesn't deteriorate even after many years of usage.
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.
