NH-D9DX i4 3U, Premium CPU Cooler for Intel Xeon LGA20xx (92mm, Brown)

This is my second set of Noctua coolers. Outstanding quality and performance. I installed them on Dell Precision T5610 and the temperatures are 15C lower than the stock coolers. It exceeded my expectations. With the stock coolers, CPU2 was always 5-10C hotter than CPU1. This is due to the motherboard design and airflow. Although CPU2 being hotter than CPU1 is perfectly normal I find 10C (sometimes even more) temperature difference a little bit too much for my liking. With these Noctua coolers CPU2 is only 2-4C hotter than CPU1 which is fantastic. Now regarding the mounting. I had a very hard time mounting these coolers on my Dell Precision T5610. But that was Dell's fault. In contrast I have never had any issues mounting Noctua coolers on Supermicro motherboards. Let me explain. When you place the heatsink on top of the CPU it is impossible to screw the bolts into the nuts which sit bellow the motherboard. Either the bolts are too short or the springs on the bolts are too long. The nuts simply sit much deeper than on any other motherboard. Obviously I cannot make the bolts longer, so naturally I decided to make the springs shorter. I squeezed them to the maximum with pliers a few times and they did shrink a little bit. But that was not enough. Then I decided to sand them and/or cut them. Not having a dremel or any power tools made this task impossible since the springs are made out of spring steel - super tough. At that point it was obvious that I should get rid of them and fill the gap with something else. So, I went to HomeDepot and picked a lot of #10 zinc washers in order to use them as spacers. After some trial and error I discovered that 7 washers deliver the perfect height - the bolt can easily reach the nut and when tightened everything is very snug. So this is my final solution, folks. I am extremely happy with the result. My workstation sits right next to me and extremely quietly and without any hesitation runs a ton of VMs.

There aren't a lot of options for 3U CPU coolers that don't sound like a jet engine. I personally would have preferred to cheap out a little, especially since I needed two - but there just aren't any cheaper options that come close to this performance and noise level (at least, none I was able to find.) And having bought these, I have no regrets - you definitely get what you pay for. If you have a 3U case, this is the heat sink you want. Even with the fan at 100%, it's quieter than the enterprise case fans I have at their lowest setting. My old heat sinks - with their frustrating shroud to funnel the air from the case fans - would let the CPUs get to the high 70's (°C) while sounding like the case was taxing down a runway.With these, the temperature on the back CPU - which has the front one blowing directly on it - still didn't crack 60 °C at full load, while making less noise than the already quiet computer next to it. At idle, don't even worry about it - temperatures are only a few degrees above room temp. The only flaw in the design that I can see is that it is possible - just barely, if you are extremely bone-headed - to mount the heat sink with the plastic protector still in place. The manual is very clear about not doing this, and it's a real struggle to do. You'll definitely get the impression that something isn't fitting right - but if you happen to ignore all that, you can actually mount it that way. To Noctua's credit, if you happen to do so, and happen to have done so in a case with insanely powerful fans that can ramp up to 9k rpm and somehow manage to keep the CPU just short of shutting itself down despite the plastic trapping most of the heat - the plastic won't melt. So at least I didn't have that mess to clean up. Clearly that was my fault, but maybe in the future the plastic shroud could extend to block the mounting screws - just in case someone as stubbornly incautious as me gets hold of one of these. Or maybe a sticker on the HSF itself, so that once you've put the instructions down and forgotten all the warnings, you are still reminded. Overall great product - clear documentation, all the tools you need, fits in the size they said it would, and amazing functionality. Worth the price.

This unit arrived extraordinarily well packed by today's standards. Very sturdy and well-cut cardboard packing as opposed to the flimsy Chinese stuff we usually get. Even the directions were clearly printed on premium stock. The unit was accompanied by a quality bondhus wrench for slipping down between holes cut in the cooling fins and used to tighten the mounting screws. Also included was a tube of thermal conducting paste in an injector format. Installation was a matter of applying the thermal paste and settling the cooling tower over the CPU and ensuring that the screws were properly located. The bondhs head wrench was a neat touch, as it made engaging the screws a cinch. A small detail that really pays off. Operation is flawless and reasonably quiet. Noctua even included instructions and hardware for mounting a second fan should that prove necessary. All of the forethought, detail and quality that went into this product makes it a clear standout among other similar products. Highly recommended.

Great CPU cooler. I bought two for my dual-Xeon build. They fit perfectly for the sockets and didn’t interfere the RAM. Installation was straightforward. They kept my Xeons (150W each) cold as ice. It kept my CPUs under 39C at 50% load. Even in turbo mode under 100% load, the temperature never exceeded 62C. This is much better than my 360mm AIO water cooler for my other CPUs. Although long term quality is yet to be determined, I would recommend it for now.

Works for narrow ILM 2011 socket, the only option that's available locally. Expensive for what it offers although it's mostly about supply and demand and the socket in question being EOL.

Ik heb een Lenovo P520 workstation en de OEM koeler krijgt de processor niet echt gekoeld, ik las online dat deze Noctua perfect past en daarom deze dus ook aangeschaft. Ik kreeg hem rechtstreeks van Noctua in Oostenrijk opgestuurd en was zeer tevreden over de verpakking en de koeler zelf uiteraard, deze voldoet perfect, is zeer geruisloos en werkt perfect. De processor is beduidend koeler (zo'n 15-20 graden lagere temperatuur dan de fabriekskoeler.

I installed this cpu cooler in my Lenovo Thinkstation P520 which went very easy. It's a pricy cooler but is so much quieter than my stock cooler and my cpu temperature is much lower.

Der Kühler ist mit einer Xeon E5-2680 v4-CPU (120W TDP) bei guter Gehäuseentlüftung selbst bei Volllast und geschlossenem Gehäuse nicht zu hören. Die CPU-Temperatur bei 100%-Last auf 14-Kernen beträgt max. 60 °C und bei Leerlauf 35 °C. Ideal geeignet für flache HTPC-Gehäuse. Wer also noch Systeme mit LGA20xx-Sockel betreibt ist hier bestens bedient. Das Zubehör ist vollständig und kommt inkl. einer guten Wärmeleitpaste.

Disipa muy bien el calor y el ventilador prácticamente no se escucha. Una opción muy buena si quieres disipación de temperatura por aire
