With a super-flat height of only 37 mm, the NH-L9a-AM5 chromax.black is ideal for particularly compact cases and thanks to its compact footprint, the cooler offers full compatibility with memory modules and VGA cards on Mini-ITX mainboards.Thanks to the extremely low heatsink (23 mm) and the 14 mm slim fan, the overall height of the NH-L9a-AM5 chromax.black is only 37 mm. This makes the cooler ideal for compact HTPCs and small form factor cases that only offer very little space for CPU coolers. The NH-L9a-AM5 chromax.black features a compact footprint that fits neatly into the keep-out zone of the AM5 socket (LGA1718). So there are no problems with other parts or components.The highly optimized NF-A9x14 HS-PWM premium fan supports PWM for fully automatic speed control and uses innovative aerodynamic construction measures and Noctua's AAO frame system. With a volume of only 23.6 dB(A) at a speed of up to 2,500 rpm and a decent 57.5 m³/h airflow, the fan shows impressive values ??despite its small size of only 92 x 92 x 14 millimeters.With the Low-Noise Adapter (LNA), the speed of the NF-A9x14 HS-PWM fan can be reduced to 1,800 rpm. If you need more power reserves, you can replace the pre-installed fan with a 92 model with a height of 25 mm.Chic stealth design with optionsThe special edition of the NH-L9a-AM5 , the chromax.black edition , is completely black .
