Noctua NH-L9A-AM4 Chromax Black Low Profile CPU Cooler
Overview
The NH-L9a-AM4chromax.black is an all-black version of
Noctuas award-winning NH-L9a-AM4 low-profile quiet
CPU cooler for AMD Ryzen based HTPCs and Small Form Factor (SFF) builds. Thanks
to the same proven heatsink design and NF-A9x14 PWM fan, it stays true to the
NH-L9a-AM4s successful formula of fusing a height of only 37mm with strong
performance and excellent quietness of operation, as well as 100% RAM and PCIe
compatibility. At the same time, the chromax.black version with its black fan
and black coated heatsink combines these assets with a sleek stealth look.
Topped off with the renowned SecuFirm2 low-profile mounting system for AMD AM4,
Noctuas enthusiast-grade NT-H1 thermal compound and
a full 6-year manufacturers warranty, the NH-L9a-AM4 chromax.black is a premium
choice for customers who seek an ultra-compact heatsink that looks just as great
as it cools.
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 or CPUs that create high heat loads. Please
consult ourCPU compatibility listto find out
whether the NH-L9a-AM4 is recommended for your
CPU/APU.
Details
Award-winning NH-L9a-AM4 cooler
Tens of thousands of enthusiast users all over the world swear by the
NH-L9a-AM4s quality and performance. Recommended by more than 50 international
hardware websites and magazines, it is renowned as being one of the best
low-profile coolers for AMD Ryzen CPUs and APUs.
chromax.black designchromax.black design
The NH-L9a-AM4 chromax.black is black from head to toe: Featuring a black
coated heatsink, a black fan with black anti-vibration pads, black fan screws
and black mounting parts, its right at home in all-black builds and easy to
integrate with other colour schemes.
37mm low profile37mm 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 compatibility100% 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-ITX100% 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 connectorsEasy 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 fanNF-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 AdaptorLow-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 with suitable CPUs/APUs that only create smaller heat
loads.
Custom-designed SecuFirm2 mounting for AM4Custom-designed SecuFirm2
mounting for AM4
The NH-L9a-AM4 comes with a custom-designed SecuFirm2 mounting system for the
AM4 socket of AMDs 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 compoundNT-H1 thermal compound
Noctuas 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.
Soldered interface between heatpipes and finsSoldered interface
between heatpipes and fins
With many heatsinks, the fins are press-fitted to the heatpipes. Due to the
different thermal expansion coefficients of copper and aluminium, this fit can
loosen over years of thermal cycling, which may lead to reduced performance. By
contrast, the NH-L9as fins are soldered to the heatpipes in order to guarantee a
superior thermal interface that doesnt deteriorate even after many years of
usage.
