Noctua DX Series 4U Intel Xeon LGA4189 CPU Cooler

Noctua DX CPU Cooler

Strong performance and 4U compatibility Noctua’s DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-D9 DX-4189 4U features a larger, custom-designed contact surface for LGA4189 platforms. Based on the proven, 92mm size NH-D9L heatsink and equipped with two of Noctua’s 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.
The NH-D9’s direction of airflow is parallel to the long axis of the LGA4189 socket, so it is ideal for server builds where the cooler’s fans should work in tandem with the airflow inside the chassis, or for workstation builds where this orientation is required for having the cooler exhaust towards the top of the case. Topped off with the professional SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound, this cooler forms a complete premium quality package for quietly cooling LGA3647 based Xeon workstations and servers.

Please note: The NH-D9 DX-4189 4U is a dedicated version for the Intel LGA4189 socket. Due to its customised larger base, it cannot be used on most other sockets and is incompatible with Noctua’s standard mounting kits.
The plastic CPU carrier frame supplied with the cooler is for LGA4189-4 (P4) only. LGA4189-5 (P5) systems use the same mounting mechanism systems but require a different CPU carrier frame. Please contact us at [email protected] if you would like to use the cooler on a LGA4189-5 (P5) type system.

Custom Designed Cooling Features

6-year Manufacturer’s Warranty Noctua products are renowned for their impeccable quality and outstanding longevity. True to this legacy, the NH-D9 DX-4189 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.


Enlarged Contact SurfaceAt 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 LGA4189-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.


LGA4189-4 (P4) CPU Carrier FrameThe scope of delivery includes an LGA4189-4 (P4) type CPU carrier frame for Intel Ice Lake-SP and Ice Lake-64L based processors (Whitley platform). However, the heatsink’s SecuFirm2™ mounting system also supports P5 type LGA4189 sockets (LGA4189-5) for Intel Cooper Lake based processors. (CPU carrier frames for LGA4189-5 are available on request via [email protected]).

DX series for Intel Xeon, Customised for LGA4189


Dual NF-A9 PWM Fans with Y-Cable The NH-D9 DX-4189 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-4189. 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.).

SecuFirm2 Mounting System with Standard Intel Parts Integrating standard Intel parts such as the anti-tilt mechanism, Torx® T30 PEEK nuts and LGA4189-4 (P4) CPU carrier frame, the cooler’s mounting system is fully compliant with Intel’s installation guidelines and provides a familiar mounting procedure for experienced LGA4189 users. A Torx® T30 mounting tool is included.
