Know before you buy
Yes, this fan is specifically optimized for both case ventilation and radiator use. Its square frame and high static pressure make it an effective choice for pushing air through the dense fins of a radiator.
The L.N.A. is a small cable that limits the fan's maximum speed to 1200 RPM. It is a simple way to ensure the fan remains virtually silent if you do not need the full 1500 RPM performance.
The 4-pin PWM connector allows your motherboard to automatically adjust the fan speed based on your system's real-time temperature. This ensures the fan only spins as fast as necessary to keep your components cool.
The NF-A14 features integrated anti-vibration pads made of extra-soft silicone. These pads help decouple the fan from the case, significantly reducing the transfer of mechanical noise and vibrations.
The fan utilizes Noctua’s SSO2 bearing, which is designed for long-term stability and quiet operation. Noctua backs this reliability with a 6-year manufacturer warranty.
