Noctua Nh-u9dxi4 Cpu Fan Doré

IMO Noctua is the best in class! I always buy Noctua with confidence. There are two small inconveniences when installing this cooler in a Dell workstation - T5610, T5810 and similar: 1. You have to remove the springs and replace them with #10 zinc washers as shown in the picture. Otherwise you cannot screw the bolts into the nuts that are bellow the motherboard. 2. You have to remove the metal plate that covers the handle on the inside of the case panel. Otherwise you will not be able to close the case due to the height of the cooler. Of course you could go with the NH-D9DX i4 3U model which is shorter in order to be compatible with 3U cases, but I think NH-U9DX i4 provides better cooling. Noctua support think too. I asked them.

Just installed two of these in a dual Xeon Super Micro tower I bought on ebay. The system was originally setup for passive cooling and the CPUs would run at 67 Celsius when idle. Under moderate load the temp alams would set off. Both CPUs now sit at 37 Celsius under moderate load. I can actually use the server to do real work. The Noctua fans also seem fairly quiet. I'm probably going to replace all the Super Micro fans with Noctua fans and make this tower a little quieter. I'm very happy with this purchase.

I went through three water coolers. 1. Corsair h100i: Pump died 2. Kraken X61: Pump died 3. Kraken X62 (replacement): Used for a bit, decided not worth it. So much better. Cooling is a little worse as to be expected with such a small air cooler coming from big water coolers. (5820k) But absolutely no noise, no longer hearing the light hum from the water coolers, and rock solid reliability. I've installed half a dozen of these over the past few months in various machines in an effort to switch to something less likely to fail.
