Noctua NH-D14 CPU Cooler Review
Being one of the largest twin-tower coolers ever made, the size of Noctua’s NH-D14 is truly monstrous. The cooler comes with two fans pre-installed from the factory, one 120mm 1300RPM fan at the front side of the cooler and one 140mm 1200RPM sandwiched between the two cooling towers. It is noteworthy to mention that this cooler weights over 1kg, being one of the heaviest coolers we have ever tested. The NH-D14 is also 160mm tall, meaning that it will not fit inside a large percentage of cheap PC cases which may be too narrow.
The large aluminum fins of the NH-D14 offer ample heat dissipation surface for even the most demanding cooling applications. Noctua soldered the fins onto the heatpipes, enhancing both the mechanical cohesion and the performance of the cooler. Furthermore, the fins are serrated and the spacing between them is significant, minimizing noise due to air turbulence.
Six large heatpipes move through the base of the NH-D14, transferring the heat generated by the CPU to both of the cooler’s towers. The heatpipes are made out of copper but Noctua nickel-plated them, enhancing both the aesthetic value of the cooler and its long term durability, as the plating will prevent copper from oxidizing.
The lower part of the cooler’s base is made out of nickel plated copper and is perfectly smooth, although not machined down to a mirror finish. The rest of the cooler’s base is made out of solid aluminum, serving only as a mechanical support for the installation of the cooler and having no effect on its performance whatsoever.
As we mentioned before, Noctua supplies two fans with their top cooler, one being 120mm and one being 140mm large. Both fans follow the chocolate brown color theme of Noctua’s logo, feature SSO bearings (high quality self-lubricating sleeve bearings) and have notched impellers which reduce air pressure noise.
