Since we were asked again and again for 140 mm fans, we now also begin with the test of the somewhat larger case fans. As a future reference, the Noctua NF-A14 FLX, which costs approx. 21 euros, will therefore compete against the reference of our 120 mm fans in today’s individual test, which makes for a very nice comparison to work out the advantages and disadvantages of both sizes in a direct comparison. Since both fans from the same manufacturer also follow very similar design specifications, such a comparison works all the better.
By the way, on the next page you can see how and what we test and why some things are the way they are. Understanding the details is extremely important in order to be able to objectively classify the results later. The differences between many models are more in the details and THE best fan for all situations can hardly exist. There is a certain optimum in every situation and of course there are also good all-rounders. But they usually have their price. But if you plan to use 60mm radiators for example, you might save money by choosing the best model for your application, which might not perform so well as a case fan. And vise versa, of course.
The Noctua-typical beige frame also gets the typical red-brown accentuation and the same-colored rotor on this fan. You may or may not think this is nice, for a smoker’s household such a colour scheme is definitely an advantage. The rest suffer or rejoice, as the case may be. The price of about 21 euros places the NF-A14 FLX in the upper class, which is certainly no exaggeration. The workmanship is right and the performance is also groundbreaking. We have deliberately chosen the voltage controlled version in order to be able to better sound out the voltage and speed range.
The fan relies on Noctua’s second generation Self-Stabilising Oil-Pressure (SSO) bearing. The A-series fans use a rotor (impeller) with flow acceleration channels in a specially optimised frame (Advanced Acoustic Optimisation, AAO). The scope of delivery of the fan package is quite extensive and more than adequate for the price:
- Ultra-Low-Noise Adapter (U.L.N.A.)
- Low-Noise Adapter (L.N.A.)
- 3:4 Pin Adapter
- 30 cm cable extension
- 4 Vibration-Compensators
- 4 fan screws
