## Summary description

The Noctua NH-D9DX i4 3U is a compact CPU cooler featuring a 9.2 cm fan with a rotational speed range of 400 to 2000 RPM. It provides an airflow of 78.9 m³/h and utilizes a Self-Stabilising Oil-pressure Bearing for durability. With dimensions of 95 mm x 95 mm x 110 mm, this silver cooler is designed for efficient cooling in tight spaces, making it ideal for 3U cases.

## Long description

The Noctua NH-D9DX i4 3U is a compact, dual-tower CPU cooler designed for Intel Xeon platforms with LGA2011 (Square and Narrow ILM), LGA1356 and LGA1366 sockets. With a 95×95 mm footprint and a reduced height of 110 mm, the cooler is fully 3U compliant while clearing RAM slots on supported platforms. It ships with an NF-A9 PWM 92 mm fan, the SecuFirm2™ professional mounting system and Noctua's NT-H1 thermal compound to form a complete cooling solution for workstations and servers.
Advantages
The NH-D9DX i4 combines a dual-tower heatsink with the NF-A9 PWM fan to deliver improved quiet cooling performance in a compact 3U-compatible form factor. Its 95×95 mm base avoids interference with memory modules, ensuring full RAM compatibility even with tall heatspreaders. The included SecuFirm2™ mounting guarantees correct contact pressure on supported Xeon sockets, and the bundled NT-H1 thermal paste offers proven low thermal resistance and reliable application. The NF-A9 fan supports PWM automatic control and can be run at reduced top speed using the supplied Low-Noise Adaptor for lower acoustics. The package also supports a second optional fan for increased cooling capacity.
Suitable for
3U servers and rackmount workstations where height is limited
Quiet Xeon-based systems for audio, video processing or scientific workstations
Systems requiring full RAM access and compatibility with tall memory heatspreaders

Warranty: 6 years manufacturer’s warranty
How to use
Install the SecuFirm2™ mounting brackets onto the target socket following the supplied instructions for your specific Intel Xeon platform. Apply a small, even amount of the included NT-H1 thermal compound to the CPU heatspreader. Seat the heatsink onto the CPU and fasten it with the SecuFirm2™ screws to achieve correct contact pressure. Connect the NF-A9 PWM fan to the CPU fan header on the motherboard for automatic speed control. If lower noise is required, attach the supplied Low-Noise Adaptor to reduce the maximum fan speed. To increase cooling capacity, mount an optional second NF-A9 fan to the front fin stack using the included clips and connect both fans with the supplied y-cable to one header.
Usage recommendations
Use the NH-D9DX i4 in 3U enclosures and workstations where clearance above memory modules is critical. Ensure the motherboard BIOS or system software supports PWM fan control for automatic speed regulation; if acoustic priority is required, fit the Low-Noise Adaptor or run a second fan at reduced speed for improved thermal performance with minimal noise increase.
