## Long description

The Noctua NH-U9 DX-4677 is a compact air cooler designed for Intel LGA4677 platforms. It combines a 120 mm fan, an enlarged copper contact surface tailored to LGA4677 processors, a 140 mm-class heatsink design derived from Noctua’s proven NH-U14S, two NF-A15 fans in a push/pull arrangement, the SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound to provide quiet, reliable cooling for Xeon-based workstations and servers.
Advantages
The cooler offers a larger, 70×56 mm copper contact surface that improves heat transfer from large LGA4677 integrated heat-spreaders, comes with two award-winning PWM-controlled NF-A15 140 mm fans for high acoustic efficiency, and includes Noctua’s SecuFirm2™ mounting with standard Intel parts and a Torx® T30 tool for correct installation. NT-H1 thermal compound is pre-applied to ensure optimal bond-line thickness and faster assembly. A 6-year manufacturer’s warranty covers the complete unit.
Suitable for
Xeon Scalable 4th generation CPUs (LGA4677) in servers and workstations
Xeon W-series processors for workstations (w9/w7/w5/w3)
Noise-sensitive environments such as audio/video production and engineering workstations

How to use
Ensure the system is powered off and placed on a stable surface. Fit the appropriate LGA4677 plastic carrier frame (E1A/E1B/E1C) onto the CPU as required by Intel’s installation guidelines. Position the NH-U9 DX-4677 heatsink so the enlarged copper base contacts the CPU IHS, then install the SecuFirm2™ bracket using the included Torx® T30 tool and the standard Intel parts (anti-tilt mechanism, Torx T30 PEEK nuts and carrier frame). Connect the PWM fan headers to the motherboard for automatic speed control. The cooler is supplied with NT-H1 pre-applied; no additional TIM is required unless re-installing after removal.
Usage recommendations
Use the NH-U9 DX-4677 in systems where low noise and reliable, long-term cooling of LGA4677 Xeon processors is required. For optimal performance, ensure adequate case airflow and allow the motherboard to manage fan speed via PWM. If the cooler is removed, clean off the pre-applied NT-H1 and reapply a suitable thermal compound before reinstallation.
