CPU Cooler Noctua NH-L9I-17XX chromax.black — Low-profile LGA1700 cooler, 92 mm fan, 37 mm height

The Noctua NH-L9i-17xx chromax.black is an all-black, ultra-compact low-profile CPU cooler designed for Intel LGA1700 (LGA17xx family) systems, including HTPCs and Small Form Factor (SFF) builds. Measuring 95 x 95 x 37 mm and using a proven heatsink design with the NF-A9x14 PWM fan, it combines compact height with effective cooling, low noise and full RAM and PCIe compatibility. The chromax.black edition pairs this performance with a black-coated heatsink and black fan for a stealth appearance. The package includes the SecuFirm2 low-profile mounting system for Intel LGA1700, Noctua NT-H1 thermal compound and a 6-year manufacturer’s warranty.

Advantages

The NH-L9i-17xx chromax.black keeps a very low profile (37 mm) while delivering reliable cooling and quiet operation thanks to its NF-A9x14 PWM fan. Its soldered fin-to-heatpipe construction ensures a durable thermal interface that resists degradation over years of thermal cycling. The 95 x 95 mm footprint maintains 100% compatibility with mini-ITX PCIe slots and provides full RAM clearance. The all-black finish offers a discreet, uniform look for compact builds.

Suitable for

• HTPC and living-room PCs where low height and low noise are required
• Small Form Factor (SFF) and mini-ITX systems with limited clearance
• Builds that need full RAM and PCIe compatibility in a compact cooler

How to use

Install the NH-L9i-17xx chromax.black using the bundled SecuFirm2 low-profile mounting system following the motherboard and cooler instructions. Apply the included NT-H1 thermal compound to the CPU IHS, mount the heatsink on the LGA1700 socket and secure it according to the supplied manual. Connect the NF-A9x14 PWM fan to the CPU fan header on the motherboard to enable automatic speed control based on CPU temperature.

Recommendations

For best results in tight enclosures, verify case clearance and ensure unobstructed airflow around the cooler. Use the motherboard’s PWM fan control profile to balance noise and cooling, and reapply thermal compound only if the cooler is removed for maintenance or upgrades.
