Noctua NH-U9DX i4, Premium CPU Cooler for Intel Xeon LGA20xx (Brown)

I'd normally for liquid cooling in a server build, but this was a unique situation where I had an older Supermicro motherboard with dual E5-2698v3 Xeons (LGA 2011-3) in a small (non-server) case, and I needed something that would keep it cool but not sound like a jet engine. Installation was flawless. Swapping in the narrow ILM guides was a breeze. The included hex tool for locking down the standoffs even has an indentation to allow tightening from an angle. I'm amazed at how quiet these four fans (two per cooler) are and how well they cool in the same case. It's at the high end of what one would pay for a non-liquid cooler, but this is worth every penny.

Dropped temperatures 20 degrees! very high-quality, shiny, nickel, chrome, plated flawless, smooth, super flat bottom probably why it works so good need to use one of the smaller brackets for my system socket 2066 fit perfectly. do precision T 5820 I always love Noctua the products

This fit great in my 4U server. Temps are pretty good and its really quiet. Its hard to find a cooler that is short enough to fit but this one worked perfectly.

Using this on an X9 SuperMicro LGA-2011 board which requires a narrow ILM. As can be seen from the photos, (before I re-attached the fans) it clears my DIMMs just fine. This fits in a 4U case with room to spare. In the case, idle temps on my Xeon E5-2667 are 28 C. Under full load it reaches 61 C. Outside the case I did see idle temps dip to 26 C.The kit comes with the fans, a Y-cable for connecting both fans to a single header, assorted mounting arms for the different socket configurations, a hex tool for tightening the screws to the socket, two inline low-noise adapters for the fans and an instruction pamphlet. I used the Y-cable but ended up not using the low-noise adapters because this thing was already pretty quiet without them. It also came with a syringe of Noctua NT-H1 thermal compound.Instructions were easy to follow. Swapping the mounting arms for my narrow LGA-2011 took just a few minutes. I loved that I had the option to mount the cooler either as shown in the photos, or rotated 90 degrees. Fans are easily removed and replaced via a tensioned wire that keeps them attached to the fins.

I have a dual Xeon E5-2697V2 (LGA2011 sockets) SuperMicro X9DRi-F motherboard that has Narrow ILM mount points for a cooler/heatsink. The motherboard is inside a 4U SC846E16-R1200B SuperMicro chassis.The original hardware had low profile heatsinks without attached fans and an air shroud. There were some really loud fans that would work well enough to push air through the server and keep the CPUs cool. I replaced all the case fans with Noctua 80mm fans to lower the noise, but they just didn't push enough air to cool the CPUs and it would overheat with enough load.Now that I've replaced the old heat sinks (and removed the air shroud) with these coolers, the whole server stays cool (I couldn't get it to overheat with 90% CPU use) and quiet. These coolers fit in my 4U chassis with room to spare, and they came with Narrow ILM mounts that just needed to be swapped with the installed square ones. My chassis needs air to be pushed towards the back of the server, and the included brackets have ones that allow either orientation depending on your needs.

Purchased two of these products for installation on my Dell T7600 Workstation.This product was not meant to be installed on such a system, but requires a bit of effort. In short, it is now installed in my system (dual core xeon) and temperatures of my system are drastically reduced.Before installation, my CPU's were operating on average at about 60°C. In some cases, my system would shut down due to over-temperature (I do alot of heavy calculations and had to do them intermittently as much as possible so as to not over-temp my system). In some cases, I would leave the computer ON over night calculating away and in the morning after I woke up, I would find my system turned off - after rebooting, I would get a message from the system that it turned off due to over-temp.After Installation, my CPU's now operate at 30°C and sometimes as high as 35°C but that's it) under heavy demand - computer has been on for weeks calculating away (no I am not mining bit coins, I am doing some CFD research)The NOCTUA product works!!! It is whisper quiet, very efficient at cooling my system - I highly recommend this product line.

Okay so I have the Asrock X99E-ITX/AC motherboard. That crazy little mini ITX X99 motherboard with a narrow ILM mounting system. Now this is the third cooler I've tried. First was a Cooler Master Seidon 120v since the motherboard came with an adapter bracket specifically for that. That worked, but in my case (Ncase M1), it was a bit cramped and on top of that, the pump noise was awful. The case itself has nearly no noise dampening since it's so small. So I changed to a 2U server copper heatsink with a fan attached. That was quiet, but under load, my Xeon was getting a little toastier than I'd liked. Then I came across this one on Amazon. I didn't think it would fit, but I ordered it anyway. It fit perfect. There is very little room to the other side of the case, but it isn't touching and I could still put both fans on it and it blows directly out of the case. Most importantly, it keeps my temps under 60c while gaming and below 75 while stress testing while being extremely quiet. I'll definitely be buying Noctua coolers for future builds. This one checks all the boxes.
