The Noctua NH-D14 looks similar with its replacement, the NH-D15. Both coolers are large and use two fans to deliver the airflow. The NH-D14 has a dual tower design, and uses two fans for its active airflow, a single 120mm and a single 140mm.
The dimensions of the heatsink are: (H)160mm x (W)140mm x (D)158mm.
The heatsink has a dual tower design and uses both nickel-plated copper and aluminum in its construction. The heatsink has a height of 160mm and a width of 140mm. It can accommodate up to three 120mm fans or three 140mm fans.
The total weight of the heatsink with the two fans installed is 1240g.
The cooler uses six heatpipes which are made from copper. Each heatpipe has an outer diameter of 6mm and all of them are nickel-plated to not only look better but also protect the copper. The classic U shape is used for the heatpipes, to not only better move the heat but also to offer a platform for the cooling fins.
The endings of the heatpipes are exposed, and while they are not machined perfectly, they blend with the rest of the cooler. Uneven heatpipe endings is a common issue for many air CPU coolers, as the manufacturing of symmetrical heatpipes is expensive and adds more cost to the end user.
The baseplate of the NH-D14 is made from solid nickel-plated copper and has a smooth surface. As is the case with many Noctua coolers, the surface of the baseplate has a radial pattern that creates a sunburst effect.
The heatpipes of the cooler are soldered to the back side of the baseplate, thus, ensuring an optimal heat transfer between the two components.
The heatsink uses approximately 70 aluminum cooling fins, or around 35 fins per heatsink tower. These fins are made from aluminum and have a solid construction, which makes them quite hard to bend out of shape. The sides of the fins are bent downwards to not only channel the airflow but also to increase the sturdiness of the heatsink itself.
The front sides of the two towers of the heatsink have preinstalled silicone strips. These are used to not only dampen the vibrations of the fans but also to offer a good base for the fan frame to sit on.
The NH-D14 uses two fans with its factory configuration. The two fans are the NF-P12 PWM at the front and the Noctua NF-P14 PWM in the middle. Both fans have the tan and brown color scheme and use 4 Pin connectors for power.
The NF-P12 PWM has the dimensions 120x120x25 mm and a maximum speed of 1300 RPM. The NF-P14 PWM has the dimensions 140x140x25 mm and a maximum speed of 1200 RPM.
