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

Couldn’t fit with both fans on because of the RAM clearance but generally a good product, it keeps the processor at 40C and 60C to 80C underload, it is very easy to install, you only have to tighten 4 screws and thats it, it its a good product to buy

lowered my temps from 94c "stock cooler" to 75c in a time spy benchmark in a Lenovo p520 with a Xeon W-2145 but sadly had to completely remove side panel locking mechanism for it to fit my pc fyi.

Noctua is where it is at and this did not disappoint. Got 1/2 the noise and twice the cooling after replacing my water cooling system with this.

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

Nice fan. works as it should

I have a Dell Inspiron T3600 that I've been upgrading piece by piece since I got it. It now has the best CPU and GPU it can handle. Some day I'll spend a couple grand on a new gaming PC but for now, mine is good enough. I stream on Twitch and one of my viewers got this for me because I mentioned I'd been having trouble keeping my temps down. This paired with some new front fans and an extra exhaust fan work wonders on my current setup. I can play games like Valheim and Shatterline on max settings and my temps don't get higher than 65C. Easy to install. Had to clip the springs a little but there are tutorial videos on YT for that if you happen. To have the same computer I have. Although it was a gift, I'd definitely still pay for one. I planned to, but someone beat me to it!

I bought a pair of these Noctua NH-U9DX i4 to replace the stock CPU coolers in a Gigabyte R150-T61 with dual Cavium ThunderX CN8890 CPUs. I used the included Narrow ILM mounting brackets. The included Y-adapter and 4-pin connector is directly compatible with the motherboard, making it a super simple upgrade.
