Noctua ha mentioned that these coolers are ideal for creating whisper-quiet high-end workstations using Intel’s just-announced Sapphire Rapids based W-3400 and W-2400 series Xeon processors for LGA4677. In addition to the new DX-4677 coolers, the NM-i4677 mounting kit allows Noctua DX-4189, DX-3647 and TR4-SP3 series coolers to be installed on LGA4677.
“Our DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors”, says Roland Mossig (Noctua CEO). “The latest revision for LGA4677 comprises 14, 12 and two 9cm models, covering anything from spacious workstation cases to 4U rack-mount servers.”
The new NH-U14S DX-4677, NH-U12S DX-4677, NH-U9 DX-4677 and NH-D9 DX-4677 4U are dedicated, customized solutions for Intel’s professional LGA4677 platform (Sapphire Rapids), which makes them an ideal fit for both 4th generation Xeon Scalable CPUs (Platinum, Gold, Silver or Bronze) and W-3400 or W-2400 series Xeon processors for workstations such as the w9-3495X, w7-3465X or w7-2495X. Whereas the large 14cm NH-U14S DX-4677 and 12cm NH-U12S DX-4677 are an excellent choices for tower-style cases and thus lend themselves to use in high-performance quiet workstations, the smaller NH-D9 DX-4677 4U and NH-U9 DX-4677 fit 4U cases, which makes them perfect for more compact workstations as well as 4U class rack-mount servers that need to run as quietly as possible.
While the NH-U9’s direction of airflow is perpendicular to the long axis of the LGA4677 socket, the NH-D9’s direction of airflow is parallel to the long axis of the LGA4677 socket. Depending on the orientation of the socket(s) on the motherboard, choosing either the NH-U9 or de NH-D9 enables system builders to align the airflow of the cooler(s) with the exhaust fans of the chassis and thereby ensure optimal system performance. Thanks to their compact footprint, both models are ideal for building dual socket setups with motherboards where larger coolers may interfere with each other.
Integrating standard Intel parts such as the anti-tilt mechanism, Torx® T30 PEEK nuts, and the CPU-specific carrier frames (included with boxed retail CPUs and available separately for tray CPUs), the coolers’ mounting system is fully compliant with Intel’s installation guidelines and provides a familiar mounting procedure for experienced LGA4677 users. A Torx® T30 mounting tool is included.
In addition to the new DX-4677 coolers, the NM-i4677 mounting kit allows Noctua DX-4189, DX-3647 and TR4-SP3 series coolers to be installed on LGA4677.
