Noctua introduces NH-U14S DX-4677 air-cooled radiator
In February of this year, Noctua announced the launch of four new cooling solutions: the NH-U14S DX-4677, NH-U12S DX-4677, NH-U9 DX-4677, and NH-D9 DX-4677 4U, designed to support Intel’s latest Xeon WX-3400 and Xeon WX-2400 series processors based on Sapphire Rapids and employing the LGA 4677 socket. Additionally, Noctua released the NM-i4677 mounting kit, allowing DX-4189, DX-3647, and TR4-SP3 series coolers to be installed on LGA 4677 sockets.
Recently, Noctua officially introduced the NH-U14S DX-4677 air cooler, capable of dissipating 700W of heat under full load from the Xeon W9-3495X. The operating platform also includes the ASUS Pro WS W790E-SAGE SE motherboard, paired with SK Hynix’s DDR5 EC8 RDIMM, and powered by a SeaSonic PX-1600 PSU.
Although all-in-one liquid cooling solutions have become increasingly popular in recent years, Noctua’s air-cooling designs continue to be highly sought after by many users.
The voluminous NH-U14S DX-4677 air cooler measures 150mm x 111mm x 165mm, with a fan-inclusive weight of 1136 grams. It features six copper heat pipes, an expansive copper base (70mm x 56mm), and large aluminum cooling fins, utilizing welded joints and nickel plating techniques specifically designed for Intel’s latest LGA 4677 socket. Equipped with two NF-A15 HS-PWM fans, it boasts rotational speeds ranging from 300 RPM to 1500 RPM, a maximum airflow of 140.2 m³/h, and a maximum noise level of only 24.6 dBA.
Noctua CEO Roland Mossig has previously stated that the DX series coolers have become the default premium silent cooling solutions for Intel Xeon processors. The NH-U14S DX-4677, in particular, is an excellent choice for tower cases and high-performance workstations.
