## Overview

The Noctua NH-L9a-AM4 is a premium ultra-low profile CPU cooler designed specifically for AMD AM4 sockets, boasting a minimal 37mm height ideal for small form factor and HTPC builds. Its compact footprint guarantees full compatibility with RAM modules and PCIe slots on mini-ITX motherboards, while the advanced NF-A9x14 PWM fan delivers exceptional cooling performance with whisper-quiet operation. Equipped with the SecuFirm2 mounting system and Noctua’s renowned NT-H1 thermal paste, this cooler combines effortless installation, reliable thermal management, and a 6-year warranty, making it the go-to choice for professionals seeking silent, efficient cooling in compact Ryzen systems.

## Description

The NH-L9a-AM4 is the latest version of the popular Noctua low profile NH-L9a fan dedicated to CPU cooling. This is the version specifically designed for configurations in SFF (Small Form Factor) or HTPC format with AMD Ryzen. With a height of only 37 mm, the NH-L9a is ideal for cases with very low height as its small footprint ensures perfect compatibility for both RAM modules and PCIe slots and allows easy access to connections around the socket including compact mini-ITX motherboards. The SecuFirm2 mounting system, specifically designed for the AM4 socket, makes installation simple. The NF-A9x14 92mm high-tech fan, whose speed can be fully automated via PWM, also allows the NH-L9a-AM4 to operate with astonishing silence. Packed with Noctua's famous NT-H1 thermal compound, the NH-L9a-AM4 brings together – in a premium pack dedicated to Ryzen CPU/APU for ITX and HTPC environments – everything users have been used to expecting larger Noctua coolers. The NH-L9a-AM4 is an ultra-compact low-profile silent fan for small SFF and HTPC enclosures. Despite its impressive level of performance, it is nevertheless not suitable for overclocking and is not suitable for CPU/APU with TDP (Thermal Design Power) greater than 95W. Please refer to our TDP guide to check the suitability of your CPU/APU with the NH-L9a-AM4. New version dedicated to the Ryzen AM4 socket. The original NH-L9a designed for AM2(+), AM3(+), FM1 and FM2(+) has received more than 50 awards and recommendations from international press and specialized sites. The new version for AM4 is based on the same advanced technology features that made this success to ensure the ultimate level of performance for Ryzen CPUs and APUs for a compact model. Low height of 37 mm. With a slim 23mm radiator combined with the NF-A9x14 low profile fan with a thickness of no more than 14 mm, the NF-A9x14 offers a total height of only 37 mm, making it ideal for HTPCs and Small Form Factor enclosures that leave little space available for the cooling fan CPU Full RAM compatibility. The NH-L9a-AM4's small footprint perfectly meets AMD's keep-out zone requirements. This means that neither the fan nor the fan encroach on the slots dedicated to RAM modules, ensuring compatibility with high memory modules. Full compatibility with VGA cards on mini-ITX. Some AMD mini-ITX motherboards have a PCIe slot close to the CPU socket area. While larger coolers spilling over this critical area prevent the use of the PCIe slot, the NH-L9a-AM4's compact form factor ensures full compatibility with PCIe cards. Easy access to near-socket connectors. Many low-rise coolers are equipped with larger fans or heatsinks for performance reasons and thus encroach on the socket area. It then becomes difficult or impossible to access the connectors surrounding the socket on congested ITX motherboards. The NH-L9a-AM4 is compact and offers free access to connectors and other surrounding components. NF-A9x14 PWM: A high-performance fan. The NF-A9x14 fan is a highly optimized premium model, featuring an exclusive Noctua AAO frame and an advanced design offering exceptional aerodynamic performance. PWM compatible, with fully automated speed, the NF-A9x14 keeps the NH-L9a-AM4 surprisingly quiet. Low Noise Adapter. By offering the ability to reduce the ceiling speed of the NF-A9x14 PWM (1800 rpm instead of 2500 rpm), the low-noise adapter (L.N.A.) provided allows for almost inaudible configurations with CPUs with a TDP of less than 65W. SecuFirm2 mounting system specific for the AM4. The NH-L9a-AM4 comes with a version of the SecuFirm2 mounting system specifically designed for AMD Ryzen configurations with AM4 socket. By allowing the fan to be attached from the back of the motherboard, this system offers extremely easy installation while maintaining the qualities and security of the SecuFirm2 system. Thermal paste NT-H1. Noctua NT-H1 is a professional TIM solution offering minimal thermal resistance, ease of application and unparalleled reliability. Constantly acclaimed by overclockers and passionate users, this product has become THE undisputed reference for premium thermal compounds. 6 year manufacturer's warranty. Noctua products have earned a solid reputation for their high quality and exceptional longevity. Like all Noctua fans, the NF-A9x14 has an MTTF of over 150,000 hours of testing, and the NH-L9a pack comes with a 6-year manufacturer's warranty.

Review: You get what you paid for. Price is much cheaper on desertcart compared to other sources
Review: Ich habe den Noctua L9a mittlerweile schon dreimal für verschiedene Systeme gekauft und bin jedes Mal aufs Neue überzeugt. Als jemand, der früher bei einem Mitbewerber im Bereich Kühltechnik gearbeitet hat, kann ich sagen: Noctua setzt seit jeher den Standard. Die Qualität und die Leistung dieses Kühlers sind einfach herausragend. Der L9a ist besonders für kompakte Builds oder HTPCs ideal. Trotz seiner geringen Größe liefert er eine sehr gute Kühlleistung und ist dabei unglaublich leise. Der Einbau gestaltet sich dank der klaren Anleitung und der durchdachten Konstruktion problemlos – auch in engen Gehäusen. Was mich besonders beeindruckt, ist die leise Laufweise. Selbst bei längeren Belastungen bleibt der Kühler nahezu unhörbar. Als jemand, der viele Kühler verschiedener Hersteller getestet und eigene mitentwickelt hat, kann ich sagen, dass Noctua immer der Maßstab für hochwertige und zuverlässige Kühlungstechnologie war und auch heute noch ist. Fazit: Der Noctua L9a ist ein exzellenter Kühler, der in jeder Hinsicht überzeugt. Ich werde ihn auch in Zukunft wieder wählen und kann ihn jedem empfehlen, der auf Qualität, Leistung und geringe Lautstärke setzt!

Exceeded my expectations for the low profile AM4 CPU heatsink, Noctua's customers service is second to none! I first bought the L9a heatsink and had Noctua sent me the AM4 kit free of charge because the at the time the L9a-AM4 wasn't not available yet, the AM4 kit for the L9a arrived at my door in a week but unfortunately I could not remove the bottom plate screws that held the older bracket in place in order to replace it with AM4 one without circling the screws (they were on too tight which is a good sign of build quality but a nightmare to remove in my case). I contacted Amazon and returned the L9a without hassle just as the L9a-AM4 was available on Amazon sold by Noctua and I ordered the L9a-AM4 as the replacement, the heatsink arrived very fast through Amazon's shipping service and I this time around had not trouble mounting the heatsink (which included Noctua excellent NT-H1 thermal compound) on my Ryzen CPU. I needed a low profile cooler which does not exceed 57mm in height and this heatsink did and exceeded the job being both efficient at cooling all the while being quiet on noise, currently I'm able to get a 3.9Ghz overclock on my Ryzen CPU with max temperatures of 70 degrees Celsius under full load and 60 - 65 degrees Celsius when gaming which is quite feat on it's own considering the size of the heatsink and the size of my mini ITX case (which is a Cooler Master Elite 110). All in all a great buy considering Noctua's great customer service, the cooling performance, form factor and noise this heatsink offers for AM4 adopters who need a low profile heatsink...no need to look elsewhere this heatsink is one of the very best.
