Noctua today released a higher speed PWM version of its award-winning NF-A14 140 mm fan. Its performance-oriented 1500 rpm top speed and comprehensive speed control options make the NF-A14 PWM an elite choice for users who strive to strike a perfect balance between excellent cooling capacity and superb quietness of operation, be it on watercooling radiators, on heatsinks or in case ventilation. "Our NF-A15 and NF-A14 fans have been very well received by customers and hardware journalists alike", says Mag. Roland Mossig (Noctua CEO), "but 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." Introduced in late 2012, Noctua's NF-A15 and NF-A14 140 mm fans have already received more than 50 awards and recommendations from leading international hardware websites and magazines. So far, only the round frame NF-A15 was available with PWM support for automatic speed control though. While the NF-A15's round frame is ideal for use on CPU heatsinks, the new NF-A14 PWM now combines PWM support with the A14's square frame that lends itself to use as a case fan or on watercooling radiators. Like the NF-A14 FLX and ULN models, the new PWM version complies with Noctua's AAO (Advanced Acoustic Optimisation) standard and features sophisticated aerodynamic design measures such as Flow Acceleration Channels. Noctua's custom designed NE-FD1 PWM IC and reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, a Low-Noise Adaptor and 6 years manufacturer's warranty, the NF-A14 PWM is a premium choice for the highest demands.
