Noctua - Bild

The NH-L9a is a premium quality quiet CPU cooler for AMD based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9a is ideal for extremely slim cases and due to its 92x114mm footprint, it provides excellent compatibility with tall RAM modules and other components on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for AM3+/FM1/FM2/FM2+ makes installation a child’s play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9a runs remarkably quiet. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9a fuses everything users have come to expect from Noctua’s larger coolers into a super-compact package for slim HTPC systems.

Caution: The NH-L9a 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 with up to 65W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9a is recommended for your CPU.



NH-L9 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.

NH-L9 100% RAM compatibility
The NH-L9a 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.*

NH-L9 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 provides full compatibility with PCIe cards.

NH-L9 NF-A9x14 PWM premium fan
The highly optimised 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.button

NH-L9 Low-Noise Adaptor
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.

NH-L9 Custom-designed SecuFirm2™ mounting for AMD
The NH-L9a bundles a custom-designed SecuFirm2™ mounting system for AM2(+)/AM3(+)/FM1/FM2/FM2+ that offers extended compatibility with mini-ITX boards and makes installation easier than ever, all while maintaining the trusted SecuFirm2™ quality.

NH-L9 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. button

NH-L9 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.

*Some mini-ITX mainboards violate the 96x114mm keep-out zone specified by AMD, so the NH-L9a can only be used with low-profile RAM (<28mm) on these boards. Please consult our compatibility list for details.
