Introduction – The NF-F12 PWM 120mm Fan & Specifications

Noctua Focus Flow 120mm Fan & Bundle

Legit Reviews is no Stranger to Noctua and their unique color scheme. The first time we looked at a Noctua fan was back in 2009 when we had a look at the S12B-FLX fan from Noctua’s FLX (Flex) series of fans, designed to operate in multiple configurations from Standard to “Ultra Low Noise.” More recently, we had a look at the Noctua NH-C14 Top-Down CPU Cooler which featured a pair of NF-P14 FLX Fans, which were Noctua’s last entry into the fan market.

Today we have the honor to look at their brand new Focus Flow 120mm fan, the NF-F12 PWM. The Focus Flow 120mm (NF-F12 PWM) is a brand new Pulse Width
Modulation fan which has vastly improved on Noctua’s old designs with
the brand new Focus Flow technology to improve airflow & static pressure. Likewise, Noctua did not stop there, and also implemented its brand new NE-FD1 PWM IC as well as the brand new SSO2 bearing.


Before we get into the technical side of things, we might as well have a look at the specifications of Noctua’s NF-F12 PWM fan.

*All Values are given as a ±10% Figure
**L.N.A. stands for “Low Noise Adapter” which is a resistor cable designed to reduce voltage to the fan by 3v.
***Values converted from Noctua’s measurements in m³/h to CFM.

Overall, you’re looking at a fairly impressive fan, to say the least. Noctua has gone out of their way to beat the 2:1 Airflow to Noise ratio that’s most common on 120mm fans, as well as have a fairly astute pressure rating with this fan as well. By all respects, this is definitely looking to be a performance part from Noctua’s factories.
