Manufacture # Noctua | Model # NH-L9a-AM4
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.
Features:
- 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.
- The NH-L9a-AM4 has a compact footprint that fully complies with the socket keep-out zones specified by AMD.
- Some AMD-based mini-ITX motherboards have the PCIe slot located close to the CPU socket zone.
- 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.
- The highly optimised, award-winning NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures.
- The NH-L9a-AM4 comes with a custom-designed SecuFirm2™ mounting system for the AM4 socket of AMD’s Ryzen platform.
- 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.
