Best 140mm Case Fan

The NF-A14 is a brilliant and premium quality 140mm fan that comes with a square frame. It complies well with the AAO (Advanced Acoustic Optimization) standard. The square shape and mounting holes make the case fan an ideal product for water cooling radiators. The fan features a great aerodynamic design that leads to Flow Acceleration Channels and further improves quiet cooling performance. The NF-A14 is one of the best case fans that are available in the market right now.

The case fan is integrated with Low-Noise-Adaptor to reduce the maximum speed of the fan during any PWM control between 1500rpm to 1200rpm. The fan also comes with 4-pin fan headers that facilitate better speed control. If you are looking for a performance-oriented fan that delivers 1500rpm, and a variety of speed control, then the NF-A14 PWM is an excellent choice for all of your requirements.
