## Summary description

Noctua NH-U9DX i4 is a compact processor cooler with an aluminium heatsink and two 92 mm fans (92 x 92 x 25 mm) delivering up to 64.3 m³/h airflow. It measures 125 mm in height, 95 mm in width and weighs 640 g. Fans run 300–1,600 RPM at 12 V, producing 13.1–17.6 dB noise. Designed for LGA 2011-v3 sockets, it provides reliable CPU cooling with low noise and long MTBF (150,000 h).

## Long description

The Noctua NH-U9DX i4 is a compact 9.2 cm CPU cooler designed for Intel Xeon platforms. The tower cooler stands 125 mm tall, uses an aluminium heatsink with a brown finish and includes two Noctua NF-B9 PWM fans for automatic speed control. It supports LGA2011 (Square ILM and Narrow ILM), LGA1356 and LGA1366 sockets and is supplied with the SecuFirm2™ mounting system and industrial-grade NT-H1 thermal compound.
Advantages
The NH-U9DX i4 combines effective airflow and low noise thanks to dual NF-B9 fans running between 300 and 1600 RPM and delivering up to 64.3 m³/h. Its 125 mm height preserves full 4U compatibility for rack or compact tower systems. The SecuFirm2™ mounting ensures secure installation on supported Xeon sockets, while the included NT-H1 thermal paste simplifies setup and improves thermal contact.
Suitable for
Cooled Intel Xeon workstations and servers using LGA2011, LGA1356 or LGA1366 sockets
4U chassis and compact server/tower builds where height is limited
Systems requiring quiet but reliable CPU cooling under sustained load

How to use
Mount the NH-U9DX i4 using the supplied SecuFirm2™ kit following the socket-specific instructions included in the package. Apply a small, even amount of the bundled NT-H1 thermal compound on the CPU heatspreader before seating the heatsink. Connect the two PWM fan headers to the motherboard fan headers or a fan controller to enable automatic speed regulation. Ensure sufficient case airflow and clearances inside the chassis for proper operation.
Usage recommendations
For stable temperatures and low noise, use motherboard fan control profiles or a PWM fan controller to adjust fan curves based on CPU load. Verify compatibility with your chassis and memory modules before installation due to the cooler’s tower design and fan placement.
