The NH-L9a-AM4 is the latest, AM4-specific
revision of Noctua's award-winning NH-L9a low-profile CPU cooler for AMD
Ryzen-based HTPCs and Small Form Factor (SFF) systems. At a height of
only 37mm, the NH-L9a is ideal for extremely slim cases and, due to its
small footprint, it provides 100% RAM and PCIe compatibility as well as
easy access to near-socket connectors even on tightly packed mini-ITX
motherboards. The custom-designed SecuFirm2 mounting system for the AM4
socket makes installation child's play and, thanks to the highly
optimised NF-A9x14 92mm fan that supports fully automatic speed control
via PWM, the NH-L9a-AM4 runs remarkably quietly. Topped off with
Noctua's renowned NT-H1 thermal compound, the NH-L9a-AM4 combines
everything users have come to expect from Noctua's larger coolers into a
super-compact, premium-quality package for ITX and HTPC builds with
Ryzen CPUs or APUs.
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 our TDP guidelines to find out whether the
NH-L9a-AM4 is recommended for your CPU/APU.
New revision for Ryzen's AM4 socket
Since the original NH-L9a for AM2(+), AM3(+), FM1 and FM2(+) has
received more than 50 awards and recommendations from international
hardware websites and magazines, the new AM4 revision builds on the same
proven heatsink design to provide excellent low-profile cooling
performance for Ryzen CPUs and APUs.
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.
100% 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.
100% 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 using CPUs with less than 65W TDP.
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.
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.
