Noctua NH-D9DX i4 3U, Premium CPU Kühler für Intel LGA2011 (Square & Narrow ILM), LGA1356 und LGA1366 (92mm, Braun)

Good product Cools our Dell T320 edge server by around 10 degrees give or take

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.

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.
