Noctua NH-L9i-17xx chromax.black, 92 mm Low-profile CPU Cooler

This cooler is a dedicated low-profile air cooling solution engineered for Intel LGA1700 and LGA1851 sockets. Its critical dimension is the ultra-compact 37 mm height, a specification that permits installation in Small Form Factor (SFF) enclosures and HTPCs where vertical clearance must be minimized. The heatsink assembly features a construction utilizing nickel-plated copper base material and aluminum fins, with thermal energy transfer managed by two integrated heat pipes.

Thermal dissipation is handled by a single 92 mm NF-A9x14 fan, utilizing SSO2 bearing technology to ensure operational stability and longevity. The fan supports Pulse-Width Modulation (PWM), enabling dynamic rotational speeds ranging from 600 RPM to 2500 RPM relative to processor thermal load. At maximum speed, the cooling unit generates 33.84 CFM of airflow and achieves a static pressure of 2.11 mmH₂O. The acoustic signature peaks at 23.6 dB, and the system design maintains 100% compatibility with both RAM and PCIe slots on supported motherboards.
