Mounting kit Noctua NM-I4677 for LGA 4677 processors

The Noctua NM-i4677 mounting kit enables installation of Noctua DX-4189, DX-3647 and TR4-SP3 series coolers onto Intel LGA4677 sockets used by 4th generation Xeon Scalable (Platinum, Gold, Silver, Bronze) processors and Intel workstation CPUs in the w9, w7, w5 and w3 series. The kit integrates standard Intel elements such as the anti-tilt mechanism, Torx® T30 PEEK nuts and CPU-specific carrier frames (these frames are included with boxed retail CPUs and are available separately for tray CPUs). A Torx® T30 mounting tool is included. The NM-i4677 is compliant with Intel installation guidelines and provides the familiar mounting procedure used for LGA4677 systems. Caution: the NM-i4677 is only compatible with Noctua DX-4189, DX-3647 and TR4-SP3 series heatsinks and cannot be used with other Noctua coolers.

Advantages

The NM-i4677 uses Intel-standard components to ensure compatibility with LGA4677 installation practices and includes a Torx® T30 mounting tool for convenience. Its design supports secure attachment of supported Noctua coolers to server and workstation motherboards while following Intel’s anti-tilt and mounting specifications. The compact package and durable materials provide a reliable mounting solution for 4th generation Xeon Scalable and related workstation CPUs.

How to use

Follow the motherboard and cooler manufacturer instructions when mounting the kit. Install the CPU-specific carrier frame (included with boxed CPUs or purchased separately for tray CPUs), fit the anti-tilt mechanism and secure the heatsink using the Torx® T30 PEEK nuts provided. Use the included Torx® T30 tool to tighten fasteners to the torque recommended by Intel and the cooler manual. Verify proper seating and even contact between cooler and CPU before powering the system.

Recommendations

Only use the NM-i4677 with compatible Noctua DX-4189, DX-3647 or TR4-SP3 series heatsinks. Do not attempt to adapt this kit to other cooler models. Follow Intel and Noctua mounting torque and installation instructions to ensure safe and reliable attachment.
