Noctua NH-L9A-AM4 Low Profile CPU cooler

The NH-L9a-AM4 is the latest, AM4-specific revision of Noctua's award-winning NH-L9a low-profile cooler for AMD Ryzen-based HTPCs and small form factor (SFF) systems. With an ultra-flat height of only 37mm, the NH-L9a is ideal for smaller cases, and thanks to its compact footprint, the cooler not only offers full compatibility with tall memory modules and PCIe cards but also allows easy access to socket-proximate ports, even on densely populated mini-ITX motherboards. The package is rounded off by Noctua's renowned NT-H1 thermal paste, thus combining the NH-L9a-AM4 with the advantages of larger Noctua coolers in an extremely compact, completely high-quality all-in-one package for ITX and HTPC systems with Ryzen CPUs or APUs.
The NH-L9a is an extremely compact, quiet low-profile cooler designed for use in small cases and HTPC environments. The cooler features outstanding cooling performance in its class but is not suitable for overclocking and is only recommended for CPUs or APUs with a TDP (thermal design power) of up to 95W. Please consult our TDP guidelines to verify if the NH-L9a-AM4 is suitable for your CPU/APU.

New revision for the Ryzen socket AM4


37mm height
Thanks to the extremely low heatsink (23mm) and the 14mm slim NF-A9x14 fan, the total height of the NH-L9 is only 37mm. This makes the cooler ideal for compact HTPCs and small form factor cases that offer very little space for CPU coolers.

100% RAM compatibility
The NH-L9a-AM4 features a compact footprint that precisely fits within the keep-out zones specified by AMD.

100% compatibility with PCIe cards on mini-ITX
On some AMD-based mini-ITX motherboards, the PCIe slot is located close to the CPU socket area. While larger coolers that extend beyond this zone may occasionally block the PCIe slot, the compact NH-L9a-AM4 offers full compatibility with PCIe cards.

Easy access to socket-proximate ports
With its compact footprint, the NH-L9a-AM4 offers convenient access to all ports and components.

NF-A9x14 PWM premium fan
The highly optimized NF-A9x14 premium fan supports PWM for fully automatic speed control and utilizes innovative aerodynamic construction measures as well as Noctua's AAO frame system. This keeps the NH-L9a-AM4 remarkably quiet.

Low-Noise Adapter
With the Low-Noise Adapter (L.N.A.), virtually silent systems can be realized with CPUs under 65W TDP.

Custom SecuFirm2 mounting system for AM4
Of course, the proven SecuFirm2 quality remains unchanged.

NT-H1 thermal paste
Noctua's renowned NT-H1 is a professional TIM solution that combines minimal thermal resistance with excellent application comfort and outstanding reliability. As a popular choice among overclockers and enthusiasts worldwide, NT-H1 has become an established standard for premium thermal pastes.


Noctua products are known for their flawless quality and outstanding durability, and like all Noctua fans, the included NF-A9x14 also has an MTTF specification of over 150,000 hours.
