Noctua NF-A14 industrialPPC-24V-2000 IP67 PWM Fans Review

Cooling/VGA & Other Cooling by stefan @ 2016-05-05

The NF-A4 industrialPPC 140mm fans are very well built and can be used for both industrial and PC chassis applications; the 24V versions are ideal as case fans because they produce little to no noise at half the voltage they receive inside a computer chassis, but if you are also planning on replacing the fans on the water cooling radiators, you have to get the 12V models. The 12V NF-A4 industrialPPC 140mm PWM fans will be ran at higher speeds in order to cool the radiator fins properly, while keeping the noise levels as low as possible thanks to the integrated technologies.

A Closer Look Part II

On the back area of the fan we can see the central sticker which has the technical specifications imprinted; Noctua also informs us that this fan is featuring a three-phase motor design with six slots, unlike most axial fans which use single-phase motors with four slots, for providing smoother transitions between the slots and thus allowing for even higher running smoothness, further reduced vibrations and very high energy efficiency. Also, thanks to the improved SSO2 bearing, the rear magnet is placed closer to the axis in order to provide even better stabilization, precision and durability:

As we have been accustomed with the previous Noctua fan models, the cable is fully sleeved:

The cable ends up with a 4-pin black PWM connector:

Next up we will discuss about the NA-SAV2 Chromax white anti-vibration mounts; each set does contain 20 mounts meant to replace the standard fan screws for enabling convenient, quick and vibration-free installation. Being available in different colors, we can adapt and personalize each and every fan depending on our build scheme:

By using the included User Manual leaflet, we can learn how the installation must be performed:
