- Sporting four heatpipes, a surface area of more than 3800cm² and two premium grade 92mm fans, the NH-U9DX i4 provides a significant upgrade in quiet cooling performance compared to common 2U solutions. At the same time, its 125mm height makes it fully compatible with standard 4U cases.
- The award-winning NF-B9 92mm premium fan features Noctua’s renowned SSO bearing as well as advanced aerodynamic optimisations such as Bevelled Blade Tips and Vortex-Control Notches. In order to achieve its superb quiet cooling capability, the NH-U9DX i4 comes equipped with two NF-B9 fans in a push/pull setup.
- The NF-B9 92mm fans supplied with the NH-U9DX i4 support PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1600 to 1300rpm using the supplied Low-Noise Adaptors for even quieter operation.
- Noctua’s SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel’s LGA2011 (both Square and Narrow ILM), LGA2066, LGA1356 and LGA1366 Xeon platforms, the SecuFirm2 mounting included with the NH-U9DX i4 guarantees perfect contact pressure and maximum convenience on all sockets.
- Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua’s NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.

Qualità … tecnologia … utilità … configurazioni ad ogni esigenza! Silenziosità e ottima circolazione d’aria … Peso che basta così!

Compré 6 unidades NH-U9DX i4 para reemplazar los ventiladores de un Workstation HP Z820 dedicado a la grabación de sonido, de modo que el bajo nivel de ruido es muy importante.
NOCTUA fabrica los mejores ventiladores y los más silenciosos.
Con los ventiladores HP (de serie) las 2 CPUs rondaban los 68º/72º grados. Después de cambiarlos por los NOCTUA la CPU apenas llegan a los 48º grados con carga plena de procesos.
RECOMENDABLE 100%

It costs a little more, but it is worth it in every other way. Good cooling, low noise, easy to put together. Keep being Noctua!

This is such an excellent cooler. Firstly I purchased two of these to use in one dual-socket 4U height server and I picked this model because with two chips in one case there was going to be a lot of heat generated so I needed a couple of good quality coolers and I wanted the server to be as quiet as possible.
So I turned to two of these i4 coolers based on the reviews and specifications from Noctua’s website I thought they would work and I have to say not only do these things cool incredibly well but they are so quiet.
BOX CONTENTS
Everything in the box feels premium, you get a nice amount of thermal grease in a tube applicator with a nice screw on lid. You get a very long tool to screw down the heatsink (feels very premium by the way), you receive a narrow-ILM bracket (the wide one is pre-installed on the cooler for your convenience) and you also receive some voltage lowering cables and a two fan to one PWM header adaptor. As I said everything in the packaging feels premium.
INSTALLATION
Installing these heatsinks is so easy, I actually had to install, uninstall and re-install them several times but not because of the heatsinks, it was due to troubleshooting issues with my CPU’s and Motherboard. So I really got to experience what these heatsinks are like to attach and remove.
Firstly probably the easiest heatsinks I’ve ever installed on a computer, the tool included is so long you can easily get it down to the bolts without unduly knocking anything around the heatsinks and the accuracy of Noctuas machining meant all the screws meet up with their holes perfectly every single time.
If you’ve looked at pictures of the heatsink you’ll see that both fans are held on to the heatsink using clips. I had to clip and unclip these a lot during my re-installations and I found them to be very sturdy with just the right amount of flex enabling you to easily remove and install them. Each heatsink has a cut grove on either side for the fans to easily slide down before you pull the clips back making installation of the fans even in a tight chassis a breeze. Noctua even included rubber glued-in slips along these grooves to dampen fan vibrations.
Also the included thermal paste was actually quite plentiful, I was able to re-use the tube of thermal paste from just one of my accessory boxes included with the i4 for all of the installs I performed during my issues which was about 5 total. Noctua isn’t providing an enormous amount of thermal grease in the package but it was enough for several attempts if you were to get it wrong on the first try.
Last thing to note here is that the instructions were very easy to read and understand. They were printed on nice paper and were concise.
PERFORMANCE
Prior to using the Noctua i4’s I was using a Supermicro 4U compatible cooler that was about twice as loud as these. It moved a lot of air with its single 90mm fan and yet the chip it cooled ran 20c hotter than with the Noctua i4’s I’m using. I went from one chip to two with one heatsink blowing its warm air into the second one and they both still cool better than that Supermicro 4U cooler did.
With an 8 core XEON E5 I’m getting around 45c under normal load conditions and 56c under 100% load conditions. Which is a big come down from 60c to 75c I was getting on the Supermicro cooler previously. This is a huge improvement.
NOISE
As I said at the beginning of the review, these coolers are so quiet. They are now the quietest pieces of equipment in my server that have fans on. I’ll likely need to swap out my case fans for Noctuas also. To think you can get this kind of low noise with such high cooling performance is incredible.
COMPATABILITY
If you’ve read the product brief from Noctua you likely know these heatsinks are designed for a 4U height chassis. I can confirm they fit perfectly, they do not foul the top lid on a 4U height case. They also do not hang over the memory modules if you’re using wide-ILM sockets which is the default mounting mechanism installed on the cooler. I was able to access the closest memory modules to the CPU socket without removing the heatsinks which is a great time saver.
My only comment about spacing is if your sockets are very close together for example some LGA 2011 / LGA 2011-v3 dual-socket motherboards try to stick two sockets almost right up against each other to fit within an ATX or EATX form factor, on these motherboards you may not be able to get both sets of fans on each of your two heatsinks. Obviously this isn’t an issue if you’re using a single-socket motherboard or a dual-socket with wide spacing as I am.
CONCLUSION
Really fantastic heatsink and fan combo. The quality is just so great, from the mirror finish cold plate at the bottom to the shiny fins and heatpipes the high quality silent yet performative fans and the easy installation these are probably the best air coolers I’ve used yet and I’ll definitely be looking at future Noctua products for other builds I do, I really cannot recommend these heatsinks enough.
