Noctua's CPU coolers of the DX-series are the first choice for years, when it comes to quiet premium cooling solutions for Intel Xeon processors. The NH-U12S DX-4677 has a larger, specially designed contact area for LGA4677. With its proven NH-U12S based on 120 mm heat sink and two the many times awarded LF-A12x25 120 mm fans via PWM, it offers a convincingly balanced combination of cooling power, compatibility and quiet operation. The all-round high-quality package of the NH-U12S DX-4677 is completed by the professional SecuFirm2™ mounting system as well as the pre-applied NT-H1 heat conductive paste – a real premium solution for the quiet cooling of LGA4677-based Xeon workstations and servers.
DX-series for Intel Xeon
Noctua's DX series, founded in 2008, has become an established reference when it comes to quiet, high-quality air cooler for Intel Xeon processors. Thanks to their superior acoustic efficiency, they are suitable Ideal for workstations and servers in noise-sensitive environments (e.g. audio/video production, content creation, technical construction, etc.).
Customised for LGA4677
The new DX-4677 models are dedicated, tailored solutions for Intel's professional LGA4677 platform: Perfect for 4th generation Xeon Scalable CPUs (Platinum, Gold, Silver or Bronze) and Xeon Workstation processors w9, w7, w5 and w3!
Enlarged contact surface
The full copper contact area of the DX-4677 version is at 70x56mm more than twice the size of the standard model. It has been specially adjusted for the oversized heat spreader (IHS) of Intel's LGA4677-based processors and allows an optimal heat transfer from the CPU to the cooler socket and further on to the heat pipes to the cooling fins.
SecuFirm2™ mounting system with standard Intel parts
Thanks to the integration of standard Intel parts such as the anti-tilt mechanism, Torx® T30 PEEK nuts and the LGA4677 processor support frame (CPU carrier frames, supplied with boxed CPUs, sold separately for tray CPUs), the mounting system of the cooler fully complies with the Intel guidelines and follows the assembly process used by experienced LGA4677 users. A Torx® T30 mounting tool is supplied.
Compatible with E1A, E1B and E1C processor mounting frames
LGA4677 processors require plastic mounting frames that are supplied with boxed CPUs and are available separately from Intel sales partners for tray CPUs. The SecuFirm2™ mounting system for LGA4677 is compatible with all bracket types (E1A, E1B, E1C).
120 mm format for excellent performance and compatibility
With five heat pipes and two of the new NF-A12x25 120 mm fans the NH-U12S DX-4677 achieves an excellent cooling power, without compromising on compatibility: Its moderate height of 158mm is compact enough for most modern tower casings and with a width of 125mm it not only fits on many Dual-socket mainboards with bases in East-West orientation, but it does not protrude on many motherboards with bases in north-south alignment too via the top PCIe slot.
Two NF-A12x25 PWM fans
The NH-U12S DX-4677 is equipped with two of the frequently awarded NF-A12x25 120 mm fans of the latest generation. This exquisite push/pull Dual configuration allows remarkable silent cooling performance as measured by its relatively compact design.
PWM support and Y-cable
The NF-A12x25 premium fans on the NH-U12S DX-4677 support PWM for convenient automatic speed control via the motherboard. This means that the fans can run almost silently under low load and only turn them up when it is really necessary. The included Y-cable allows both fans to be operated and controlled via a single connection.
Pre-applied NT-H1 heat-conducting paste
Noctua's renowned NT-H1 heat conductive paste is a professional TIM solution that offers minimal thermal resistance and excellent long-term stability. That the paste is already pre-pre-pre-applied to the contact surface guarantees an optimum layer thickness and saves valuable time during assembly. Perfect for system integrators!
