Review: Noctua NH-L12

Review: Noctua NH-L12

created for


Noctua is back in the house. It's always good to have them here. We appreciate the work and effort that is put into these cooler designs and their build quality. Although some of the designs or color schemes might not speak to everyone, the performance is far from lackluster. Noctua is a respectable contender on both fronts. We will be looking at the Noctua NH-L12 today. The Noctua NH-L12 is a top-down low-profile CPU cooler geared towards the small spaces such as HTPC's and other small form factor scenarios. With a total height of just under 100mm this cooler could even be used in a 3U server rack.

Noctua NH-L12 - Profile

We have seen many companies including Noctua implementing dual fan setups. Usually with one fan in "Push" while the second is in a "Pull" configuration. This configuration has not exactly proven to be a dramatic performance enhancement; however, it has shown better overall performance and stability as well as predictability under higher frequencies and load, besides a nice side effect of reducing noise. The Noctua NH-L12 implements a second fan but not in a traditional setting. The main fan is a 120mm in "Push" mode while the "Pull" fan is only 92mm. We will explore this setup a little bit more later in the review. The build quality is as usual on the upper end of the spectrum and the ease of use is not to far behind.

What Noctua has to say about this cooler:

The NH-L12 is a low-profile quiet cooler designed for use in small form factor cases and HTPC environments. With its flexible NF-F12 (120mm) / NF-B9 (92mm) dual PWM fan setup, the NH-L12 can be configured either for full performance in dual fan mode or extra-low profile (66mm) with the top fan removed. Bundled with the award-winning NT-H1 thermal compound and Noctua's SecuFirm2 multi-socket mounting system, the NH-L12 packs everything a premium quality quiet cooler needs into a highly compact package.
