Noctua has shared a video that can confirm the NH-U14S DX-4677, one of four new CPU coolers that it recently announced for LGA4677-based Intel Xeon workstations and servers, is capable of cooling heavy loads as high as 700 watts on CPUs that include the Intel Xeon w9-3495X processor. The NH-U14S DX-4677 is available for EUR 139.90 / USD 129.90, while the NH-U12S DX-4677, NH-U9 DX-4677, and NH-D9 DX-4677 4U start at USD 119.90. The NM-i4677, a mounting kit that allows Noctua DX-4189, DX-3647, and TR4-SP3 series coolers to be installed on LGA4677, is also available for EUR/USD 29.90.
“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.”

From a Noctua press release:
The new NH-U14S DX-4677, NH-U12S DX-4677, NH-U9 DX-4677 and NH-D9 DX-4677 4U are dedicated, customised 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 choice 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.
Would you say 700W on air cooling is impossible? Here’s our NH-U14S DX-4677 cooling the Intel Xeon w9-3495X at a continuous load of more than 700W! @intel @ASUS @Seasonic @SKhynix pic.twitter.com/35HCtIxL30— Noctua (@Noctua_at) April 11, 2023
