Low-profile AMD socket CPU cooler
Overview
Noctua
Low-Profile Fan for AMD Ryzen CPUs on socket AM4
The Noctua NH-L9a-AM4 is the latest version of the popular Noctua NH-L9a low-profile fan for CPU cooling. This is the version specifically designed for SFF (Small Form Factor) or HTPC configurations with AMD Ryzen. With a height of only 37mm, the NH-L9a is ideal for cases with a very low profile, as its small footprint ensures compatibility with both RAM modules and PCIe slots and allows easy access to connections around the socket, even on compact mini-ITX motherboards. The SecuFirm2 mounting system, specifically designed for the AM4 socket, makes installation a breeze. The high-tech NF-A9x14 92mm fan, whose speed can be fully automated via PWM, also allows the NH-L9a-AM4 to operate with surprising silence.
Special AMD AM4 versionThe original NH-L9a for the AM2(+), AM3(+), FM1 and FM2(+) has received more than 50 awards and recommendations from the international press and specialist websites. The new version for AM4 builds on the same advanced technology features that have made it so successful to ensure the ultimate level of performance for Ryzen CPUs and APUs in a compact design. With a slim 23mm heatsink combined with the NF-A9x14 small form factor fan that is only 14mm thick, the NF-A9x14 offers an overall height of only 37mm, making it ideal for HTPCs and small form factor cases that leave little space for the CPU's fan. The small footprint of the NH-L9a-AM4 perfectly meets AMD's requirements for a keep-out zone. This means that neither the fan nor the cooling unit encroaches on the RAM module slots, thus ensuring compatibility with high memory modules. |

Reliable, efficient and quietSome AMD mini-ITX motherboards have a PCIe slot close to the CPU socket area. While larger fans that extend into this critical area prevent the PCIe slot from being used, the compact size of the NH-L9a-AM4 ensures full compatibility with PCIe cards. Many low-profile fans have larger fans or heatsinks for performance reasons, which encroach on the socket area. This makes it difficult or impossible to access the connectors around the socket on crowded ITX motherboards. The NH-L9a-AM4, on the other hand, allows free access to the connectors and other components around the socket due to its compact size. The NF-A9x14 is a highly optimised premium fan with a unique Noctua AAO frame and advanced design for outstanding aerodynamic performance. PWM compatible, with fully automatic speed control, the NF-A9x14 keeps the NH-L9a-AM4 surprisingly quiet. With the ability to reduce the NF-A9x14 PWM's top speed from 2500rpm to 1800rpm, the included Low Noise Adapter (L.N.A.) allows for nearly inaudible configurations with CPUs having a TDP of less than 65W. |

Noctua fan
Silent when controlled by the motherboard software.
Very flat, takes up very little space.
Easy to install for someone who already knows a little about computers.
Can be complicated for someone who has never installed a cooling system.Review automatically translated -

perfect for a small footprint
My NAS is in a wardrobe without much airflow, the CPU runs at 45º idle and goes up to 60º at 100% use.

1st time for Noctua
As a fan of Be Quiet! I wanted to test Noctua. Used for a Ryzen 3 2200G, it does the job perfectly despite its small size. Processor under 50°C despite the high temperatures in a BitFenix Phenom Mini-ITX case. It is discreet and fits right on my CM ASRock A320M-ITX. This fan looks like a quality product
