CPU cooler Noctua NH-D9L CHROMAX.BLACK — 92 mm fan, 400–2000 RPM, 22.6 dB, dimensions 95×95×110 mm, weight 531 g

The Noctua NH-D9L chromax.black is an all-black compact dual-tower CPU cooler with a total height of 110 mm designed for space-restricted builds such as HTPCs and small form factor systems. With a 95×95 mm footprint it clears RAM and PCIe slots on Intel and most AMD mini-ITX motherboards. The package includes a preinstalled NF-A9 92 mm PWM fan (400–2000 RPM, up to 22.8 dB(A)), the SecuFirm2™ multi-socket mounting system, Noctua NT-H1 thermal compound and a 6-year manufacturer’s warranty.

Advantages

The NH-D9L chromax.black combines a low-profile tower layout with proven Noctua engineering to offer strong cooling performance in only 110 mm of height, maintaining full compatibility with tall RAM modules and nearby PCIe slots on small motherboards. The included NF-A9 premium fan supports PWM automatic speed control and can be paired with a second optional fan for increased performance. The all-black finish (coated heatsink, black fan, clips and mounting parts) allows unobtrusive integration into black or mixed-colour builds.

Suitable for

• Compact HTPC and small form factor (SFF) desktop builds
• 3U rack or chassis systems with 110 mm CPU cooler clearance
• Mini-ITX systems requiring full RAM and PCIe compatibility

How to use

Install the NH-D9L using the supplied SecuFirm2™ mounting hardware following the motherboard socket instructions. Apply a small, pea-sized amount of the included NT-H1 thermal compound to the CPU heatspreader, position the heatsink over the socket and secure it with the mounting system to ensure even contact pressure. Connect the NF-A9 PWM fan to the CPU fan header; to reduce noise, use the supplied Low-Noise Adaptor or allow the motherboard to regulate fan speed via PWM. For improved cooling, fit an optional second NF-A9 to the front fin stack using the included clips and connect both fans with a Y-cable to a single header.

Recommendations

Ensure case clearance of 110 mm before installation, verify that the 95×95 mm footprint does not obstruct tall memory modules or adjacent PCIe cards on your specific mini-ITX or mATX motherboard, and use PWM control or the Low-Noise Adaptor to balance noise and cooling performance according to your needs.
