Noctua NF-A14 FLX

100% Positive Reviews
Rated #27 in Case Fans


Pros: Superb airflow to noise efficiency

Cons: Price

Next up on Noctua's A series fans, we have the NF-A14 FLX, which has standard 140mm form factor. That is to say, they're 100% compatible with radiators.

It shares alot of features with the A15-PWM and F14 ULN such as blade design, rubber grommets, bearings, etc. Performance in push is excellent and so is the efficiency. Value of the latter increases with the use of included low and ultra low noise adaptors.

Pros and cons are pretty much exactly the same as the A15-PWM which I reviewed recently. Chief among cons would be the terrible whining noise in pull and push/pull mode but that has more to do with the heatsink design than the fan so it should not be an issue in mose situations.. On the positive side, it is just as quiet in a push configuration as the A15 while being able to move a ton of air at the same time. I think these fans would be perfect for radiators and watercooling setups and I can't wait to complete my watercooling test bench to see just how capable they are.

Noctua NF-A14 FLX

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The FLX version provides 1200/1050/900rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
