CPU cooler for Intel socket

Pictures may differ from actual products

With a base size of 95x95mm and a reduced height of 110mm, the NH-D9DX i4 is fully compatible with the 3U format and does not encroach on the memory slots on the LGA2011(-3) Square ILM and LGA2066 Square ILM. It is also compatible with the Narrow ILM mount.

CPU cooler for Intel socket

Overview

An exceptional silence!


Noctua's DX series of coolers has become a must-have choice for those looking for high performance and quiet cooling for Intel Xeon CPUs. The latest i4 version is compatible with the Xeon-based platforms LGA2011, LGA2011-3 and LGA 2066 (Square and Narrow ILM) and LGA1356. The addition of the NM-I3 mounting kit allows it to be compatible with the LGA775 and LGA1366 sockets.

The new 9cm (D9) model offers increased compatibility and performance compared to previous models of this size. Thanks to its 95x95mm base size and reduced height of 110mm, the NH-D9DX i4 is fully compatible with the 3U form factor and does not encroach on memory slots on LGA2011(-3) and LGA 2066.

However, its dual finned battery design combined with the NF-A9 PWM ensures even better cooling and quiet operation. Supplied with the SecuFirm2 mounting system and NT-H1 thermal paste, the NH-D9DX i4 3U is a complete high-end solution for quiet cooling of Xeon workstations and servers.
A low-profile tower fan
While slimline fans usually blow perpendicular to the motherboard (frontally), the NH-D9L is a tower model that blows parallel to the motherboard. It therefore offers better ventilation performance in cases with suction (front) and exhaust (rear) fans that create an airflow parallel to the motherboard.

Full RAM compatibility
Thanks to its 95x95mm base size, the NH-D9DX i4 does not encroach on the memory slots on the LGA2011(-3) and LGA2066 Square ILM. This provides full access to memory arrays and ensures full compatibility with optional high heatsinks and memory fans.
3U Compatibility
The NH-D9DX i4 has a height of only 110mm, a saving of 15mm compared to the previous 9cm DX series fans (which were 4U compatible). This allows the NH-D9DX i4 to be integrated into 3U cases, making it a perfect solution for applications where noise level is a sensitive issue (e.g. audio or video workstations).
NF-A9 High-End Fan
The highly optimised NF-A9 fan features an AAO Frame and numerous aerodynamic optimisations (such as Flow Acceleration Channels) that make it more efficient than previous Noctua 92cm models, maximising the cooling performance of the NH-D9DX i4.
PWM Compatibility and Low Noise Adapter
The NF-A9 92cm fan supplied with the NH-D9DX i4 is PWM compatible, allowing automatic speed control through the motherboard. In addition, for even quieter operation, the maximum speed can be capped at 2000 to 1550 rpm by using the L.N.A. adapter.
Dual Mode Compatibility (Dual Ventilation)
For users wishing to enhance cooling performance, the NH-U9L is supplied with an additional clip kit to attach an additional NF-A9 fan to the front finned battery. By using the Y-cable supplied with the NF-A9 PWM fan, it is possible to connect both fans to a single CPU fan connector.
NT-H1 Thermal Paste
A top-of-the-line TIM solution that has won more than 100 awards worldwide from trade journalists, Noctua's NT-H1 offers very low thermal resistance, reliability and ease of application.
SecuFirm2 mounting system
Noctua SecuFirm2 mounting systems have become synonymous with safety, reliability and ease of installation. Compatible with Xeon LGA2011 and LGA2066 (Square and Narrow ILM) and LGA 1356 platforms, the SecuFirm2 mounting system supplied with the NH-D9DX i4 ensures perfect contact pressure and is easy to install in any socket.
Information provided by our tech department The ventirad is also compatible with socket 775 and 1366 with the NM-I3 mounting kit.

    Irreproachable

    Like all Noctua fans it is perfect, it cools my 24 core xeon at 120w as if it was an intel core duo, it is very small and does not make too much noise.

    Perfect

    The product corresponds perfectly to what I expected.
    The mounting on a P9X79 DELUXE motherboard is very simple and my 4930k CPU has a very good cooling. I installed it in a living room PC for my videos and games, it is extremely quiet.
    I accompanied it with 3 Noctua NF-P12 PWM in a SilverStone GD09 box.
    I have no hesitation in buying it, I remain loyal to Noctua who make quality products.

    For server motherboards

    I had the basic intel ventirad, super noisy even in idle.

    I changed both of them for noctua, it's really quiet even when it starts to heat up (you really have to load the mule for a long time for it to start heating up).

    By experience I also bought a noctua for my I7 920 in 2010, I'm currently on an I 5850k and I still have the same Noctua ventirad in 2016, the fans are still silent and efficient as in the first day.

    Quality

    Great product and very easy to place on a 2011-3 socket. However, it is said to be compatible with socket 1366 but you need the adapter kit (to be bought separately).

    Very compact, quiet and possibility to add a fan. Good quality thermal paste.

    Thanks LDLC
