Noctua includes all necessary mounting hardware and accessories needed to setup and install both the NH-D15S and the NH-C14S into your system, including fans, motherboard and fan mounting hardware, mount install tool, and thermal compound. Aside of the mounting cage orientation, both units share similar CPU mounting and fan hardware.
For cooler to board mounting, Noctua includes kits with detailed instructions for both Intel and AMD type sockets. They even differentiate between the LGA115x and LGA2011 sockets with separate manuals for each because of the slight differences in mount hardware.
For Intel LGA 115X sockets, you use the included backplate with integrated uprights in conjunction with the included plastic spacers, metal brackets, and thumbscrews to build the board mount. The backplate is not used for LGA2011 sockets. Instead, the included metal stand-offs are screwed directly into the provide socket holes.
For AMD sockets, you fix the C-shaped brackets in place over the white plastic spacers with the included screws going directly into the stock AMD back plate.
Noctua includes an L-shaped Phillips head screwdriver to help with mounting the cooler to the mounting bracket, long enough to clear the radiator. It can also be used to remove the center screw holding the hold-down plate to the top of the CPU block. Also bundled in with the cooler is a tube of Noctua's own NT-H1 thermal compound and a Noctua-branded metal case badge.
Keeping in-line with their current mounting kits, the included LGA115x backplate has its uprights permanently fixed to the backplate. This eliminates the possibility of the uprights spinning in place while attempting to set the cross brackets in place. It also makes for much easier construction of the LGA115X mounting cage on the board.
For the LGA115X mounting cage, the black plastic spaces slip over the threaded uprights in the base plate with the metal cross brackets sitting on top of them. The brackets are held in place via thumbscrews screwed into the uprights. The nuts fixed to the cooler's mounting bracket screw into the threaded uprights located on the top center of the board mount brackets.
The Intel mounting cage is designed to allow for mounting the cooler in a vertical (front-to-rear) or horizontal (bottom-to-top) orientation, depending on the orientation of the mounting cage's cross brackets. In the horizontal orientation (which is also the default mounting orientation for the NH-C14S cooler), the mounting cage has no contact or fit issues in the CPU socket area allotted.
In the vertical orientation (which is the default orientation for the NH-D15S cooler), the mount cage fits perfectly into the CPU socket area as well.
On an Intel LGA115X board, the base plate bottom rests on the socket bottom plate, eliminating direct board contact except for the arms housing the threaded uprights. This design minimizes the potential for contact or crushing of any components in close proximity to the socket base plate.
Noctua included two sets of fan mounts to use the coolers in the default single fan mode or optional dual-fan mode. To use the NH-D15S in tri-fan mode, you would need to contact Noctua for an additional set of wire fan mounts. Noctua also included a low noise adapter, for reducing the fan speed to a whisper quiet 1200 RPM (revolutions per minute).
The fan mounts are held to the fan via the front upper and lower holes on the fan. The hooks on the inside of the mount go into the holes on the front face of the fan so that the mount sits vertically on either side of the fan. The body of the mount then snap in place to the hooked sections on the sides of the radiator.
For heat dispersal, Noctua packaged one of their NF-A15 140mm fans in with the NHD15S unit. The NF-A15 is rated for a maximum speed of 1500 RPM with a rated maximum airflow potential of 82.5 CFM (cubic feet per minute). The brown colored fan body sits in a tan colored housing with a total of seven large fan blades. The fan blades have shaped fins along the inside top of the blade to assist in directing airflow into the radiator and minimize the airflow dead spot in the fan's center caused by the motor. The fan cables are sleeved in a dense, black colored plastic sleeving and ending in a 4-pin PWM-style power connector. The fans is rated to run at 12V, drawing 0.13 amps of power during full speed operation.
For NH-C14S, Noctua packaged in one of their NF-A14 140mm fans. With specs similar to the AF-A15 fan, The NF-A14 is rated for a maximum speed of 1500 RPM with a rated maximum airflow potential of 82.5 CFM (cubic feet per minute). The major difference between the AF-14 and AF-15 fans is the outer housing shape. The AF-15 has a rounded housing while the AF-14 is a more traditional square housing. The brown colored fan body sits in a tan colored housing with a total of seven large fan blades. The fan blades have shaped fins along the inside top of the blade to assist in directing airflow into the radiator and minimize the airflow dead spot in the fan's center caused by the motor. The fan cables are sleeved in a dense, black colored plastic sleeving and ending in a 4-pin PWM-style power connector. The fans is rated to run at 12V, drawing 0.13 amps of power during full speed operation.
