FAQ:

Q: Is the Noctua NF-A12x25 PWM an all rounder?

A: Following the approach of Noctua’s A-series, the NF-A12x25 is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators.

Q: Which is the next generation Noctua 120mm fan?

A: The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance.

Q: What’s the maximum speed of the NF a12x25 PWM fan?

A: This makes the fan remarkably quiet even at very close distances. The NF-A12x25 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 2000 to 1700rpm. The L.N.A. can be used either to run the fan at a fixed speed of 1700rpm or to cap the maximum speed when using automatic PWM control.

Q: What is the silicone gasket on the NF-A12x25?

A: The NF-A12x25 includes a silicone gasket that can be used when installing the fan on watercooling radiators or other applications that benefit from a tighter seal with the fan. The gasket helps to damp minute vibrations and to reduce air loss between the fan and the radiator for optimal cooling performance.
