Accessories and Documentation
For those looking to use this cooler with an Intel processor, this is the kit you need. Across the top are the black plastic spacers that the top brackets rest on, the four nuts to secure the top brackets, and for those with LGA2011/2066 motherboards, there are four standoffs specific to those sockets. At the bottom are the pair of top brackets on either side of the LGA115X backplate, which sports washers around the posts to isolate it from the motherboard.
AMD users need a different bit of kit to get the cooler adequately installed. At the top are a couple of sets of spacers, the lighter ones for AM2/3 and FM sockets, while the darker set is specific to AM4. Along with the provided screws and the top brackets installed to the factory backplates, you are all set with this hardware to get the cooler attached.
The universal bits found in the hardware box are as follows. There is a full-size tube of NT-H1 paste suitable for many applications, a screwdriver to help with mounting the hardware as well as the cooler, and also a metal case badge. When it comes to the fans and connectivity, Noctua supplies not only a Y-splitter cable so that one motherboard fan header can power both fans, but they also include a pair of NA-RC14 low noise adapters which reduce the maximum voltage of the fans for even less noise.
While many manufacturers will throw together some instructions, which mainly consists of images and little text to go along, Noctua goes the other direction. Not only are the renderings easy to follow, but the text answers all questions. Going a step further, Noctua also separates the various types of installs into three manuals, reducing any confusion when it comes to getting the NH-U12A installed.
