Noctua NH-D9 DX-4677 4U

NOCTUA NH-D9 DX-4677 4U: Premium Quiet Cooling for Intel Xeon LGA 4677Experience the pinnacle of quiet, high-performance cooling for your professional workstation or server with the NOCTUA NH-D9 DX-4677 4U CPU Cooler. Engineered specifically for Intel´s LGA 4677 socket, this cooler is the definitive choice for powering the latest Xeon Scalable processors (Sapphire Rapids) in 4U rack-mount chassis and other space-constrained environments. It masterfully combines a compact footprint with the signature thermal efficiency and near-silent operation that has made Noctua a world-renowned leader in premium cooling solutions.The NH-D9 DX-4677 is built upon a proven dual-tower heatsink design, optimized to deliver exceptional heat dissipation. This is paired with two of Noctua's state-of-the-art NF-A9 PWM 92 mm fans. This push/pull dual-fan configuration generates superior airflow and static pressure, efficiently drawing heat away from your CPU even under sustained, heavy workloads. The result is stable, reliable performance for your mission-critical applications, all while maintaining an impressively low noise profile.Key Benefits:* Optimized for 4U Server Environments: With a total height of 134mm, the NH-D9 DX-4677 offers full compliance with standard 4U server chassis, providing a premium-grade cooling solution where larger coolers simply won´t fit.* Whisper-Quiet Operation: The dual NF-A9 fans feature Noctu´s advanced aerodynamic design and SSO2 bearings, ensuring exceptionally quiet operation. For ultra-low-noise requirements, the included Low-Noise Adaptors (L.N.A.) can be used to further reduce fan speed and noise levels without a significant impact on performance.* Exceptional RAM and PCIe Compatibility: The compact 95x95mm footprint of the cooler, a direct result of its 92 mm fan size, ensures it does not overhang the RAM slots on LGA 4677 motherboards. This guarantees easy access to memory modules and 100% compatibility with any RAM height, while also avoiding interference with PCIe slots.* Effortless and Secure Installation: The cooler comes equipped with the professional SecuFirm2™ mounting system, custom-designed for the LGA 4677 socket. With pre-installed mounting brackets and an included Torx T30 mounting tool, installation is straightforward, secure, and provides optimal contact pressure for maximum thermal transfer.* Ready for Immediate Use: To streamline the installation process, the NH-D9 DX-4677 comes with Noctu´s award-winning NT-H1 thermal compound pre-applied to the heatsink base, ensuring a perfect, mess-free application and outstanding long-term thermal performance right out of the box.Main Features:* Proven dual-tower heatsink design for maximum cooling efficiency.* Customized SecuFirm2™ mounting system specifically for the LGA 4677 platform.* Powered by two highly optimized NF-A9 PWM 92 mm premium fans.* Full 4U chassis compatibility for server and workstation builds.* Excellent clearance for memory modules and
