CPU cooler Noctua NH-L9x65 chromax.black low-profile 65 mm height, 92 mm fan, 2500 RPM

Noctua NH-L9x65 chromax.black is a low-profile CPU cooler with a total height of 65 mm. It features a single 92 mm fan that reaches up to 2500 RPM, providing quiet and reliable airflow for compact HTPC and small-form-factor systems. The cooler is finished in black and does not include illumination.

Advantages

The cooler's low 65 mm height enables installation in tight spaces where clearance is limited. A single 92 mm fan delivers effective airflow at up to 2500 RPM while maintaining a low noise level of 23.6 dB. The chromax.black finish offers a uniform black appearance suitable for discreet builds. No illumination reduces power use and avoids unnecessary visual distraction.
