The Noctua NH-U9 DX-4189 is a high-performance CPU cooler designed specifically for Intel Xeon processors with the LGA4189 socket. It is ideal for use in 4U servers and systems that require compact cooling solutions without compromising on thermal efficiency. The cooler features a single-tower design with six heatpipes and two NF-A9 premium fans arranged in a push-pull configuration to maximize airflow and minimize noise. Its compact size ensures compatibility with PCIe components and allows for easier installation in tight server chassis.
The NH-U9 DX-4189 is engineered to support the latest 3rd generation Intel Xeon Scalable processors, including Platinum, Gold, Silver, and Bronze variants, as well as the W-3300 series. This makes it suitable for high-performance computing environments and data centers where reliable cooling is essential. The dual NF-A9 fans provide excellent airflow while maintaining low noise levels, thanks to their PWM support for automatic speed control based on system load. This ensures the cooler remains silent during idle periods and ramps up performance when needed.
Installation is made simple with the included LGA4189-4 CPU carrier frame and Torx T30 mounting tool. The pre-applied NT-H1 thermal compound ensures optimal heat transfer from the CPU to the cooler, reducing the need for additional application. The design emphasizes ease of use and reliability, making it a preferred choice for both professionals and enthusiasts who value precision and efficiency in their cooling solutions.
The NH-U9 DX-4189 comes with a 6-year manufacturer’s warranty, reflecting Noctua’s confidence in its product quality and durability. This long warranty period provides peace of mind for users who rely on their systems for critical operations. The cooler’s compact height of 125mm also makes it suitable for systems with limited vertical space, ensuring compatibility with a wide range of server and workstation cases.
