Noctua NH-U14S-DX-3647 Xeon Performance CPU Cooler For LGA3647

 

Overview

Noctua NH-U14S-DX-3647 Xeon Performance CPU Cooler For LGA3647

Noctuas DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-U14S DX-3647 features a larger, custom-designed contact surface and supports both square and narrow type LGA3647 platforms. Based on the proven, 140mm size NH-U14S heatsink and equipped with Noctuas award-winning, PWM controlled NF-A15 140mm fan, it combines maximum performance and superb acoustics. Topped off with the professional SecuFirm2 mounting system and pre-applied NT-H1 thermal compound, the NH-U14S DX-3647 forms a complete premium quality package for quietly cooling LGA3647 based Xeon workstations and servers.

DX series for Intel Xeon

DX series for Intel Xeon

First introduced in 2008, Noctua’s DX line CPU coolers have become a standard choice when it comes to quiet, premium grade air cooling solutions for Intel Xeon processors. Thanks to their superior acoustic efficiency, they are ideal for workstations and servers that run in noise sensitive environments (e.g. audio/video production, content creation, engineering, etc.).

Customised for LGA3647

Customised for LGA3647

The new DX-3647 line coolers are dedicated, customised solutions for Intel’s professional LGA3647 platform, which makes them an ideal fit for both Skylake-SP based Xeon Scalable CPUs (Platinum, Gold, Silver or Bronze, Purley series) and Xeon-Phi processors (code names Knight’s Landing or Knight’s Mill).

Enlarged contact surface

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 LGA3647-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.

Supports square and narrow type LGA3647 sockets

Supports square and narrow type LGA3647 sockets

The heatsink’s SecuFirm2™ mounting system includes two sets of brackets in order to support both square and narrow type LGA3647 sockets. Thanks to pre-installed mounting screws and the included processor clips (square type and narrow type without Omni-Path fabric connector, with fabric connector on request), the installation procedure is easy, quick and secure.

140mm size for maximum performance

140mm size for maximum performance

With six heatpipes, a fin surface area of more than 6000cm² and the large, highly optimised NF-A15 140mm fan, the NH-U14S DX-3647 provides a superior level of quiet cooling efficiency. This makes it ideal for building cutting-edge, ultra high-performance Xeon-based workstations that run almost silent.

NF-A15 140mm premium fan

NF-A15 140mm premium fan

Complying with Noctua’s AAO standard and featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 has quickly built up a reputation as one of the best 140mm heatsink fans on the market.

PWM support

PWM support

The renowned NF-A15 140mm premium fan supplied with the NH-U14S DX-3647 supports PWM for convenient automatic speed control through the motherboard, which allows it to run near silent at lighter loads and speed up only when necessary.

Anti-vibration pads and fan-clips for second NF-A15 (optional)

Anti-vibration pads and fan-clips for second NF-A15 (optional)

For users who want to achieve even better performance by adding a second, optional NF-A15 fan to create a push/pull setup, the NH-U14S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.*

Pre-applied NT-H1 thermal compound

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!

6-year manufacturer’s warranty

6-year manufacturers warranty

Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NH-U14S DX-3647 heatsink is built to last, and like all Noctua fans, the supplied NF-A15 unit features an MTTF rating of more than 150,000 hours. The entire package comes with a full 6-year manufacturer’s warranty.
