In Figure 4, you see the side of the cooler. The NH-C14 has an unusual design, with a horizontal heatsink and two fans blowing the air from the top to the bottom. The manufacturer claims you can use this cooler three different ways: with two fans for maximum performance, with only the upper fan for high clearance (for example, if you have memory modules with tall heatsinks), or only with the lower fan for low profile needs.
In Figure 5, you can see the front of the cooler, where you can check the shape of the fins. The fans do not touch the heatsink directly, but use rubber pads to absorb vibrations.
In Figure 6, you check the cooler rear side.
In Figure 7, you can see the cooler from the top, where the top fan is visible.
