Over the years Noctua has created some memorable premium offerings but at a seemingly slow, deliberate pace with high attention to detail. They've kept the same design aesthetic over the years, making their products easily recognizable and presumably streamlining fabrication. Uniformity is part of their strategy to the point where every heatsink released in a given year has identical packaging, accessories, and mounting hardware. It's not all just for show either, as they invariably produce elite performance and often the only valid complaint is price. In many ways, Noctua is the Apple of CPU coolers.

The NH-U14S.

The last Noctua we reviewed, the NH-U12S, was a slim tower heatsink with a 120 mm fan that offered high efficiency in a more compact form factor than the usual fare. The NH-U14S is its big brother, a more substantial version with a 140 mm blower. Compared to the NH-U12S, it's 7 mm taller and thicker, and 25 mm longer, though by modern day standards it's still rather slender. Both coolers look a bit undersized compared to their respective stock fans. The narrow physique of the NH-U14S is specifically designed to not overhang memory slots on LGA2011 boards as well as most LGA115x and AMD models.

The box.

Package contents.

The gear included in the package is neatly segregated into three different boxes. The longer box contains common accessories: a long screwdriver, an extra pair of fan clips, an additional set of anti-vibration pads, a tube of thermal compound, a low noise fan adapter, and a metallic case badge. The mounting hardware for Intel and AMD sockets is separated into their own respective boxes as well.

Like the NH-U12S, the Noctua's old universal Intel backplate has been replaced with a fixed LGA115x version. LGA1366 and LGA775 users aren't left entirely in the cold though as Noctua provides an optional compatible mounting kit for free. It still seems rather bizarre that they'd abandon a perfectly good backplate for a more limited one and then provide the old one at no extra charge. It may be that they streamlined manufacturing of the backplate to cut costs and are using an excess stock of adapter kits to give away to the few, dwindling users who need them. For LGA2011, the heatsink mounts directly to the socket frame while for AMD installs, the stock backplate is reused.
