the NH-C14S is a re-factored version of the Noctua's NH-C14 cooler, built to accommodate a wider variety of board designs. The cooler features a single top or bottom-mounted 140mm fan, nickel-plated copper heat-pipes and CPU base plate, and a densely-finned aluminum radiator. Noctua designed the unit's seven integrated heat-pipes out of nickel-plated copper to optimize heat absorption from the CPU base plate and heat transfer to the aluminum radiators. The aluminum radiator was designed to facilitate optimal transfer of the heat from the heat-pipes to the air medium. The thin nickel plating covering the base plate and heat-pipes give both corrosion and scratch resistance, while maintaining optimal heat transfer between the cooler's interconnected components.

The NH-C14S's single radiator was designed with a fin density of 12 fpi (fins per inch) with a thickness of almost double that of a standard fan. The radiator's thickness requires the user of a higher pressure fan to drive sufficient airflow through it for effective cooling. The construction of the individual radiator fins adds an immense amount of surface area for heat dissipation with the heat pipes soldered to each of the fins for structural integrity and optimal heat transfer to the radiator fins.
From a side view of the cooler, you can easily see the how the design works to enhance the air flow through and heat dissipation of the radiator. The integrated heat pipes are mounted through the radiator's middle and arranged in a straight line along the width of the unit for more uniform heat distribution. The heat pipes terminate in the base plate sitting directly below the radiator, giving the structure a "C" shape. Noctua strengthened the sides of the radiator with an integrated line of spacers along the center point, giving the radiator more structural integrity as well as an air guide to aid in directing the air through the radiator fins. The NH-C14S comes standard with a single 140mm fan, but supports up to a dual fan configuration. Integrated into the sides of the radiator are the standard hook configurations designed into most Noctua radiator-based coolers, used to hold the fans in place. The wire fan holds have two set of straight sections that lock into the hooked sections of the radiator to firmly secure fans to the front and/or rear sides of the radiator.
Integrated into the cooler's base is its top mounted hold down plate with two spring-loaded screw-in nuts, giving the unit more than enough force for a solid CPU surface mount. The heat pipes go through the base plate with six of them almost flush with the CPU surface and the seventh pipe bisecting the upper section of the block assembly. The additional material in the block gives it enhanced heat capture capabilities with the upper heat pipe useful in redirecting the excess captured heat to the radiator. Additionally, the position of the block directly under the radiator allows for direct cooling of the block via the radiator's fan.
The unit's base plate is a seamless copper plate with nickel-plating to prevent corrosion and surface scratches. The base plate is fixed to an upper plate to which the hold down assembly is fixed, sandwiching the copper heat pipes. The heat pipes run through the lower portion of the base plate, in close proximity to the CPU surface, to ensure optimal heat transfer. The base plate is machined flat and polished to a mirror-like sheen, ensuring a near perfect mating surface with the CPU.
The cooler fits to the Z87 test board well in its default orientation with the heat pipes facing the PCIe slots. The fit is tight with the fan mounted below the radiator, but does manage to clear the motherboard's integrated VRM heat sinks. When used with a board with larger heat sinks or with memory modules in closer proximity to the CPU socket, the unit's fan would need to be shifted to a top mounted configuration. In testing, we found their to be no difference in cooling performance using either fan mounting configuration.
As shown, the cooler can be mounted with the heat pipes facing either PCIe slots or the right edge of the motherboard. You would likely run into spacing issues between the primary system video card and the cooler when mounted with the heat pipes oriented to the right side of the board. For the closeup picture of the block, you can see that the heat pipes fit tightly in the socket, but do manage to clear the board's VRM sinks.
