Noctua NH-L9i, 92 mm Low-profile CPU Cooler

The Noctua NH-L9i is a highly compact CPU air cooler specifically engineered for Intel LGA 115x and LGA 1200 sockets in space-constrained small form factor (SFF) builds. The unit maintains an ultra-low profile height of 37 mm, ensuring full mechanical compatibility with thin Mini-ITX chassis and low-profile HTPC enclosures. Its footprint is standardized to guarantee clearance above RAM modules and PCIe slots on supported motherboards. The cooler is rated to reliably dissipate heat for processors consuming up to 65W Thermal Design Power (TDP).

Heat is transferred from the nickel-plated copper base via two 6mm heat pipes and subsequently dispersed through the densely packed aluminum fin stack. Cooling is provided by a single 92mm NF-A9x14 PWM fan, which supports automatic speed regulation via its 4-pin connector. The fan operates within a minimum speed of 300 RPM up to a maximum of 2500 RPM. This operational range results in noise levels between 14.8 dB and 23.6 dB while generating a maximum static pressure of 2.11 mmH₂O.
