## Summary description

Noctua NH-U9DX i4 is a compact tower CPU cooler with a 92 mm aluminium-bladed fan delivering up to 64.3 m³/h airflow. It operates at 300–1600 RPM with a peak noise level of 17.6 dB and runs on 12 V. Dimensions are 95 × 120 × 125 mm. Designed for effective heat dissipation in space-constrained server and workstation systems.

## Long description

Noctua NH-U9DX i4 is a compact tower processor cooler designed for Xeon-based workstations and servers where space and noise constraints matter. The cooler stands 125 mm tall and uses a 92 mm aluminium-bladed fan that operates from 300 to 1600 RPM, providing up to 64.3 m³/h of airflow with a maximum noise level of 17.6 dB. The unit is compatible with Intel LGA2011 (Square ILM and Narrow ILM), LGA1356 and LGA1366 platforms and is supplied with a professional mounting system and thermal compound for immediate installation.
Advantages
The NH-U9DX i4 combines a small footprint with efficient heat dissipation and low acoustic emissions. Dual 92 mm fans with PWM support enable automatic speed adjustment to balance cooling performance and noise. Its 125 mm height preserves compatibility with 4U chassis and other space-constrained enclosures, while the aluminium-bladed fan and tower design maintain consistent airflow across the heatsink. Included industrial-grade thermal compound and a secure mounting system simplify installation and improve thermal transfer.
Suitable for
Xeon-based workstations and rack-mount servers with LGA2011, LGA1356 or LGA1366 sockets
4U and other space-constrained chassis where cooler height must be limited
Environments requiring low-noise operation and reliable continuous cooling
Key specifications
Fan size: 92 mm
Fan speed: 300–1600 RPM (PWM)
Airflow: up to 64.3 m³/h
Noise level: 17.6 dB (maximum)
Rated voltage: 12 V
Dimensions (H×W×D): 95 × 120 × 125 mm
Design: compact tower heatsink with dual 92 mm fans
Bundled thermal compound: industrial-grade thermal paste included
How to use
Mount the NH-U9DX i4 onto a compatible Intel LGA2011, LGA1356 or LGA1366 CPU socket using the supplied SecuFirm2™ mounting hardware. Apply the included industrial-grade thermal compound to the CPU heatspreader following the paste manufacturer’s instructions, then secure the heatsink to ensure even contact. Connect the fan PWM cable to the motherboard fan header to enable automatic speed control. Verify clearance within the chassis before final assembly, especially in 4U rack units or compact workstations.
Usage recommendations
For optimal cooling and quiet operation, ensure the system chassis has unobstructed airflow, set motherboard fan control to use PWM, and periodically clean the heatsink and fans to prevent dust accumulation. Use the cooler in systems where its 125 mm height and dual 92 mm fan configuration match chassis and airflow requirements.
