CPU cooler Noctua NH-L9i chromax.black, low-profile 92 mm fan, LGA1151/LGA115x/AM4 support, 37 mm height, 95x95 mm heatsink

The Noctua NH-L9i chromax.black is an all-black, ultra-compact low-profile CPU cooler designed for HTPCs and Small Form Factor (SFF) systems. It combines a slim 23 mm heatsink and the 14 mm NF-A9x14 PWM fan to achieve a total height of 37 mm while maintaining strong cooling performance, low noise levels and full compatibility with RAM modules and PCIe cards on mini-ITX boards. The package includes Noctua's SecuFirm2™ low-profile mounting system for Intel LGA115x, the NT-H1 thermal compound and a Low-Noise Adaptor for reduced fan speed.

Advantages

The NH-L9i chromax.black offers a proven heatsink design with soldered fins and heatpipes for a durable thermal interface, a premium NF-A9x14 PWM fan that supports automatic speed control, and an all-black appearance with black fan, anti-vibration pads and mounting parts for easy integration into dark or monochrome builds. Its 95×95 mm footprint matches the Intel LGA115x keep-out zone to ensure 100% RAM and PCIe compatibility on compact motherboards. Included accessories such as the NT-H1 thermal paste and L.N.A. further increase installation flexibility and allow near-silent operation on CPUs with lower TDP.

Suitable for

• HTPC and living-room compact PCs
• Small Form Factor (SFF) and mini-ITX builds
• Systems requiring full-height RAM compatibility
• All-black or stealth-themed PC builds

• Compatible sockets: Intel LGA115x (LGA1150/1151/1155/1156); optional adapter available for AMD AM4
• Colour: Black

How to use

Install the NH-L9i chromax.black using the included SecuFirm2™ low-profile mounting system for Intel LGA115x following the manufacturer’s instructions. Apply a small, even amount of the included NT-H1 thermal compound onto the CPU heatspreader, position the heatsink over the socket area and secure it with the provided mounting hardware. Connect the NF-A9x14 PWM fan to the CPU fan header on the motherboard to enable automatic speed control. If lower noise is needed and the CPU TDP is below ~65 W, fit the Low-Noise Adaptor to reduce the fan’s maximum speed.

Recommendations

For optimal results ensure the cooler fits within your case’s 37 mm clearance and check motherboard keep-out zones for socket compatibility. Use the included Low-Noise Adaptor when building near-silent systems with CPUs of lower TDP, and order Noctua’s optional AM4 mounting kit if you need AMD AM4 support.
