Noctua LGA4677 CPU Coolers for Intel Xeon Processors

The new DX-4677 line coolers are dedicated, customised solutions for Intel’s professional LGA4677 platform, which makes them an ideal fit for both 4th generation Xeon Scalable processors.

NH-U9 DX, NH-D9 DX, NH-U12S DX and NH-U14S DX

Noctua’s DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The coolers features a larger, custom-designed contact surface for LGA4677 platforms. Based on the proven Noctua heatsinks and equipped with two of Noctua’s award-winning, PWM controlled fans, they combine maximum performance and superb acoustics. Topped off with the professional SecuFirm2 mounting system and pre-applied NT-H1 thermal compound, the coolers forms a complete premium quality package for quietly cooling LGA4677 based Xeon workstations and servers.

Enlarged contact surface

At 70x56mm, the heatsink’s copper contact surface is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of Intel’s LGA4677-based processors, this customised design allows for an optimal heat flow from the CPU over the base to the heatpipes and on to the cooling fins.

Dual Noctua premium fans

The coolers are equipped with two of Noctua’s award-winning fans. This powerful push/pull dual fan configuration allows it to achieve an unrivalled level of quiet cooling performance and makes it the first choice for workstations that require the best possible cooler, period.

Pre-applied NT-H1 thermal compound

Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance and outstanding long-term stability. Having the paste pre-applied to the heatsink base ensures optimal bond-line thickness and saves precious time in installation. Ideal for system integrators!

Compatible with E1A, E1B and E1C carrier frames

LGA4677 processors require plastic CPU carrier frames for installation, which are included with retail boxed CPUs and available separately via Intel sales partners for tray CPUs. The SecuFirm2 mounting for LGA4677 is compatible with all types of carriers (E1A, E1B, E1C).

Socket compatibility

Please note that these coolers are a dedicated version for the Intel LGA4677 socket. Due to its customised larger base, it cannot be used on smaller sockets and is incompatible with Noctua’s mounting kits for these sockets. For more information regarding compatibility, please take a look at Noctua’s Compatibility Centre.
