On Figure 9 you can see the complete contents of the three bags that come with the cooler: one with the installation hardware for AMD processors, one with Intel socket 775 parts and the last one with parts that are common to both kinds of CPU. As you can see the difference between the two sets is the shape of the plate installed under the motherboard and of the clips that fasten the cooler to the motherboard.

To install this cooler you must attach the corresponding holder on the motherboard and screw the tabs shown in Figure 10 to the cooler base, just like what happens on NH-U12P model.

Before installing the fan it is recommended to stick both adhesive silicon strips that come with the product to the heatsink, so they will help to absorb the fan vibration, reducing the noise level.

On Figure 12 you can see NH-C12P with its fan installed. But in order to install the cooler on the motherboard it is necessary to remove the fan, so you can access the screws that you need to tighten in order to hold the cooler on the holder that you installed on the motherboard.

On Figure 13 you can have an idea how it looks inside our case. Even though it is not as tall as NH-U12P, it is a big cooler, fitting in "normal" tower cases but not on some SFF (Small Form Factor) models.
