The Noctua NH-D9 DX-4677 4U is a high-performance CPU cooler designed for Intel Xeon processors with LGA4677 and LGA4710 sockets. It is specifically tailored for use in 4U servers, offering a compact design that ensures compatibility with PCIe components. The cooler features a dual-tower structure with four heatpipes, providing efficient heat dissipation while maintaining a low profile of 125mm in height. This makes it ideal for environments where space is limited but cooling performance is critical.
The dual NF-A9 premium fans offer excellent airflow and noise control, with PWM support allowing the motherboard to adjust fan speeds based on temperature. This ensures the cooler remains quiet during idle periods while delivering maximum cooling capacity when needed. The push-pull configuration enhances airflow across the CPU, improving thermal efficiency. The fans are known for their reliability and are designed to operate silently under normal conditions.
The cooler comes with pre-applied NT-H1 thermal compound, which is highly regarded for its thermal conductivity and long-term stability. Installation is simplified with the included Torx T30 mounting tool, making it easier for users to set up without requiring additional tools. A CPU carrier frame is required for installation, which is typically included with boxed retail CPUs or available separately for tray CPUs.
This cooler is well-suited for data centers and server environments where consistent performance and quiet operation are essential. It supports both E1 (LGA4677-1) and E2 (LGA4710-2) socket types, making it versatile for different server configurations. However, users should ensure they have the necessary mounting hardware and compatible motherboards to fully utilize the cooler's capabilities.
