Noctua NH-L9A-AM4 CH.BK CPU Cooler
The NH-L9a-AM4 chromax.black is an all-black version of Noctua’s 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-AM4’s 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, Noctua’s enthusiast-grade NT-H1 thermal compound and a full 6-year manufacturer’s 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.
Award-winning NH-L9a-AM4 cooler
Tens of thousands of enthusiast users all over the world swear by the NH-L9a-AM4’s 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 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, it’s right at home in all-black builds and easy to integrate with other colour schemes.
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 with suitable CPUs/APUs that only create smaller heat loads.| Specification: | Noctua L9A-AM4 CH.BK |
