Noctua is better catering to users requiring a lower profile CPU cooler with the birth of its new NH-L12; a cooler sporting four nickel-plated copper heatpipes that should feel right at home in Small Form Factor and HTPC cases in particular.
The NH-L12 features a dual PWM fan setup in the form of a NF-F12 (120mm) PWN fan on top and an NF-B9 (92mm) fan positioned underneath. If you're dealing with minimal clearance in a highly compact mini-ITX enclosure you also have the option of switching things up for just the NF-B9 fan, which reduces the overall height of the cooler to only 66mm.
In usual Noctua fashion, Low-Noise adapters are supplied that drop the fan's maximum speed to just 1200/1300rpm if its super quiet operation you seek. The cooler also comes with a tube of Noctua's NT-H1 thermal compound and SecuFirm2 mounting system.
