The Noctua NH-L12 is composed of a copper base soldered to four copper heatpipes surrounded by 60 aluminum fins, all nickel-plated to give it a uniform look. With both fans mounted, it measures 93 x 128 x 150 mm (W x H x D) and weighs 680 grams total.

The NH-L12 is essentially a smaller version of the NH-C14, shrunk for use in smaller cases. The heatpipes are curved into a "C" with the fin mass attached to the upper portion. By our measurements the fins are 0.49 mm thick and spaced 1.51 mm apart on average.

The larger fan is clipped onto the top and the smaller one underneath, both blowing down onto the base and around the socket. The center section of fins form a trench to guide the 92 mm fan to its proper position. Isolation strips on both sides provide some dampening.

The surface of the base is slightly convex and polished to a dull shine.

Bare, the heatsink weighs 420 grams and measures 66 mm high. It resembles one of the first top-down heatpipe coolers, the Thermalright XP-120.

The 120 mm fan can be placed on the underside, but it's a tight squeeze and may interfere with motherboard components. The clearance underneath is only 47 mm, not including the fan.

The dampened corners of the 120 mm fan make it slightly thicker than the standard 25 mm.
