## Summary description

The Noctua NH-D9 DX-4677 4U is an air cooler designed for efficient CPU cooling. It features a 9.2 cm fan with a rotational speed range of 400 to 2500 RPM and utilizes a self-stabilizing oil-pressure bearing for quiet operation. Its dimensions are 95 mm in width, 120 mm in depth, and 134 mm in height, making it suitable for 4U cases. The cooler's aluminum construction and beige-brown color provide a sleek appearance.

## Long description

The Noctua NH-D9 DX-4677 4U is a low-profile air cooler developed for Intel LGA4677 Xeon processors in 4U and other space-constrained systems. It is based on Noctua’s 92 mm NH-D9L heatsink design and comes with two PWM-controlled NF-A9 92 mm fans (high-efficiency 2500 rpm version), a SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound. The cooler measures 95 mm × 120 mm × 134 mm and uses an aluminum heatsink with a beige-brown aesthetic suitable for rack and workstation builds.
Advantages
The NH-D9 DX-4677 4U delivers a balance of cooling performance and compatibility for 4U chassis thanks to its compact 92 mm dual-fan configuration and a larger, custom-designed contact surface for LGA4677 CPUs. Its PWM-controlled high-efficiency NF-A9 fans provide a wide speed range (400–2500 RPM) for adjustable cooling and quiet operation, and the included SecuFirm2™ mounting and pre-applied NT-H1 paste simplify installation and ensure reliable thermal contact.
Suitable for
4U rackmount servers and workstations with Intel LGA4677 sockets
Space-restricted systems where low-profile CPU coolers are required
Enclosures that exhaust airflow perpendicular to the socket’s long axis
Key specifications
Type: Air cooler
Model: Noctua NH-D9 DX-4677 4U
Fan diameter: 92 mm (two NF-A9 PWM fans, 400–2500 RPM)
Bearing type: SSO (self-stabilizing oil-pressure bearing)
Dimensions (W×D×H): 95 × 120 × 134 mm
Weight: 0.769 kg
Compatibility: Intel LGA4677

How to use
Install the cooler using the included SecuFirm2™ mounting system following the manufacturer’s mounting instructions for LGA4677. Remove protective covers, place the cooler onto the CPU so the custom contact surface seats evenly, and secure the mounting hardware evenly in the recommended sequence. Connect the fan headers to motherboard PWM fan headers so the NF-A9 fans are controlled automatically. Ensure there is sufficient chassis airflow in the intended direction (perpendicular to the socket long axis) for optimal performance.
Usage recommendations
For systems that require airflow parallel to the socket’s long axis, select a cooler model designed for that orientation. Verify clearance in your 4U chassis before installation and ensure chassis exhaust fans support the cooler’s intended airflow direction.
