The Noctua NH-L9a-AM4 chromax.black is an air cooling solution engineered for space-constrained PC builds utilizing the AMD AM4 socket. This low-profile cooler maintains a total height of 37 mm, ensuring broad compatibility with Mini-ITX chassis, tall RAM modules, and primary PCIe slots. The compact footprint measures 114 mm by 92 mm, precisely fitting within the keep-out zone defined by the AM4 socket specification. This design prevents overhang onto adjacent motherboard components. The unit employs two 6 mm copper heat pipes connected to an aluminum fin stack and a copper base plate.
Cooling is managed by a single NF-A9x14 HS-PWM fan, which utilizes SSO2 bearing technology for long-term operational stability. The fan speed is controllable via PWM, offering a rotational range between 600 RPM and 2500 RPM. At maximum speed, the fan generates 57.5 m³/h of airflow and registers a peak noise output of 23.6 dB. An included Low-Noise Adaptor (L.N.A.) limits maximum fan speed to 1800 RPM, reducing acoustic output to 14.8 dB. Installation on AM4 motherboards is facilitated by the SecuFirm2 mounting system and pre-packaged NT-H1 high-grade thermal compound.
Key Features:- Low-profile air cooler with 37 mm overall height
- Designed exclusively for AMD AM4 processor sockets
- Includes a 92 mm NF-A9x14 PWM fan
- Fan speed adjustable from 600 to 2500 RPM
- Maximum airflow rating of 57.5 m³/h
- All major components finished in chromax.black
- Utilizes two 6 mm copper heat pipes
- Includes SecuFirm2 mounting hardware and NT-H1 thermal paste
- Fan rated for 150,000 hours MTBF
