Noctua NH-D9 DX-3647 4U Xeon Performance CPU Cooler For
LGA3647
Overview
NH-D9 DX-3647 4U 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-D9 DX-3647 4U features
a larger, custom-designed contact surface and supports both square and narrow
type LGA3647 platforms. Based on the proven, 92mm size NH-D9L heatsink and
equipped with two of Noctuas award-winning, PWM controlled NF-A9 92mm fans
(high-efficiency 2500rpm version), it combines strong performance with excellent
compatibility for 4U systems and other space-restricted applications. Topped off
with the professional SecuFirm2 mounting system and pre-applied NT-H1 thermal
compound, the NH-D9 DX-3647 4U forms a complete premium quality package for
quietly cooling LGA3647 based Xeon workstations and servers.
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
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
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
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.
Compact 92mm size for best compatibility
Thanks to its compact footprint (95x95mm with center fan only, second fan can
be installed on either side depending on available space) and a total height of
only 134mm, the NH-D9 DX-3647 4U provides excellent PCIe compatibility and is
small enough to fit most 4U size rack-mount enclosures.
Dual NF-A9 PWM fans
The NH-D9 DX-3647 4U is equipped with two of Noctua’s award-winning NF-A9
92mm fans in their high-speed 2500rpm HS-PWM variant. This push/pull dual fan
configuration makes it possible to achieve a level of cooling performance that
is remarkable for such a compact cooler and comes close to the bigger NH-U12S
DX-3647.
PWM support and y-cable
The NF-A9 premium fans supplied with the NH-D9 DX-3647 4U support PWM for
convenient automatic speed control through the motherboard, which allows them to
run near silent at lighter loads and to speed up only when necessary. The
supplied y-cable makes it possible to power and control both fans simultaneously
from a single motherboard fan header.
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
Noctua products are renowned for their impeccable quality and outstanding
longevity. True to this legacy, the NH-D9 DX-3647 4U heatsink is built to last,
and like all Noctua fans, the supplied NF-A9 units feature an MTTF rating of
more than 150,000 hours. The entire package comes with a full 6-year
manufacturer’s warranty.

Notes
and warnings |
Please
note that the NH-D9 DX-3647 4U is a dedicated version for the Intel
LGA3647 socket. Due to its customised larger base, it cannot be used on
any other sockets and is incompatible with Noctua’s standard mounting
kits. |
