Noctua is adding a pulse width modulation version of its popular NF-A14 series of fans. The fans have a max speed of 1500RPM, and the advanced speed control options provided by PWM give the fans an impressive feature set. Like previous models in this series, the new fan comes with Advanced Acoustic Optimization as well as Flow Acceleration Channels. CEO Mag. Roland Mossig gave the reason behind the new fan, stating that "we got many requests for a square frame PWM version for use as a case fan and on watercooling radiators. We can now meet this demand with the new NF-A14 PWM."
