Description
The NH-L9a-AM4 chromax.black is a completely black version of Noctua's award-winning low profile cooler NH-L9a-AM4, designed for AMD Ryzen, HTPCs and small form factor (SFF) systems. The success story remains unchanged thanks to the same super-flat heatsink and the proven NF-A9x14 PWM premium fan: Strong cooling performance and excellent quietness at a height of just 37 mm, paired with 100% RAM and PCIe compatibility. The chromax.black version with its black fan and black coated heat sink combines these advantages moreover with a smart stealth design. Award-winning NH-L9a-AM4 cooler
Tens of thousands of hardware enthusiasts around the world swear by the NH-L9a-AM4. With recommendations of more than 50 international hardware websites it is considered one of the best low-profile coolers in the market.
Chromax black design
The NH-L9a-AM4 chromax.black is black from head to toe: With its black coated heat sink, black fans including black anti-vibration pads, black fan clips and black mounting parts it is perfect for all black systems and fits well with other color schemes.
37mm height
Thanks to the extremely low heat sink (23mm) and the 14mm slim NF-A9x14 fan, the overall height of the NH-L9 is only 37mm. Thus the cooler Ideal is suitable for compact HTPCs and small form factor housings, which offer very little space for CPU coolers.
100% RAM compatibility
The NH-L9a-AM4 has a compact footprint that fits exactly into the keep-out zones specified by AMD. This means that neither the cooler nor the fan surpass the RAM slots and thus a comfortable access to the memory as well as full compatibility with high modules is guaranteed.
100% compatibility with PCIe cards on mini ITX
With some AMD-based mini-ITX mainboards, the PCIe slot is located close to the CPU base zone. While larger coolers extending beyond this zone sometimes block the PCIe slot, the compact NH-L9a-AM4 offers full compatibility with PCIe cards.
Easy access to socket-close connections
Many Low-Profile coolers fall back on larger fans and heat sinks, in order to ensure adequate cooling power, but extend beyond the socket zone and make it on tightly fitted ITX main boards often difficult or even impossible to reach connections lying close to the socket. With its compact base, the NH-L9a-AM4 offers easy access to all connections and components.
NF-A9x14 PWM Premium-Fan
The highly optimized NF-A9x14 Premium fan supports PWM for fully automatic speed regulation and falls back on innovative aerodynamic design measures as well as Noctua's AAO frame system. The NH-L9a-AM4 thus remains remarkably quiet.
Low-noise adapter
With the Low-Noise Adapter (L.N.A.) the speed of the NF-A9x14 PWM fan can be reduced from 2500 to 1800rpm. CPUs that use low heat output to produce virtually silent systems.
Customised SecuFirm2 mounting system for AM4
The tried and tested SecuFirm2 quality remains unchanged.
NT-H1 thermal compound
Noctua's renowned NT-H1 is a professional TIM solution that combines minimal thermal resistance with excellent ease of use and outstanding reliability. As a popular choice for over-clocking and enthusiasts around the world, NT-H1 has become an established standard for premium thermal conductive pastes.
Soldering of heat pipes and cooling fins
With many coolers the cooling fins and heat pipes are connected by a simple pressing method. Due to the thermal stress applied As well as the varying coefficient of expansion of copper and aluminum, this connection can loosen over the years, leading to loss of performance by WAS. With the NH-L9a however, the cooling fins and heat pipes are soldered, WAS enables a better and stable heat transfer over many years.
