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.
