Noctua NF-A14 industrialPPC-24V-3000 IP67 and NF-A14 industrialPPC-24V-2000 IP67 PWM – TEST AND REVIEW

For the past several months I had the honor to test and review all of the major models part of the industrialPPC series, which are fans designed for heavy duty usage included in Noctua’s portfolio and that includes:

  1. Noctua NF-F12 industrialPPC-2000 and Noctua NF-F12 industrialPPC-2000 PWM
  2. Noctua NF-A14 industrialPPC-2000 and Noctua NF-A14 industrialPPC-2000 PWM
  3. Noctua NF-F12 industrialPPC-24V-3000 IP67 and NF-F12 industrialPPC-24V-2000 IP67

And to finish the series of tests, in this test and review I am going to check the Noctua NF-A14 industrialPPC-24V-3000 IP67 and NF-A14 industrialPPC-24V-2000 IP67 PWM models, which are also made with industrial purpose for supreme cooling performance while being powered with 24V. Since in the normal PC setup, there is no 24V power provided, so I will test both fans at maximum 12V.

So let’s check what these models have to offer.

To perform this test and review I received both of the fans inside the standard for the series package including the pretty simple looking black/brown carton box. On the front side of the boxes there is just the company logo, the series name and the model name added, while the full technical specifications of the products could be found on the back side of the packages.

Let’s put the packages, which are absolutely standard for the series aside and check the products.

 

NOCTUA NF-A14 industrialPPC-24V-3000 IP67 AND NF-A14 industrialPPC-24V-2000 IP67 PWM7  STRUCTURE

Noctua NF-A14 industrialPPC-24V-3000 IP67 and NF-A14 industrialPPC-24V-2000 IP67 PWM are absolutely identical fans based on the classic Noctua NF-A14 model and the only difference between them is their cooling performance corresponding to their revolutions per minute operation capabilities.

Both of the models are designed as a structure of:

A square 140 x 140 x 25 mm entirely in black matte, made from fibre-glass reinforced polyamide frame, which is the typical material used for all of the models in the series made to withstand temperatures of up to 140°C and which makes the fans even more solid and durable than the original model. Each one of the frames feature the very well known AAO Frame technology, which offers integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which designed and added to improve the fan’s performance and the noise efficiency.

Both NF-A14 industrialPPC-24V-3000 IP67 and NF-A14 industrialPPC-24V-2000 IP67 PWM feature fibre-glass reinforced polyamide propellers entirely in black with 7 very wide and at the same time not very sharply angled blades. Both of the propellers are optimized to deliver the best possible performance and noise level balance. Of course, the propellers themselves are designed with the very well know flow acceleration channels which speed up the airflow at the crucial outer blade regions. This measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noises when the air passes through the propellers.

As usual for the Noctua fans, the connection between the frames and the propellers is done by the typical for all of the series, Noctua’s SSO2 Bearing and offering the new three-phase motor, which features three-phase design with 6 slots, is made to provide smoother transitions between the slots and thus allows for even higher running smoothness, further reduced vibrations and grant much higher energy efficiency. In addition, both of the fans are supporting fully automatic PWM speed control which uses Noctua’s custom-designed NE-FD2 PWM IC for three-phase motors. The NE-FD2 integrates Noctua’s proprietary Smooth Commutation Drive (SCD) technology, which suppresses PWM switching noises and thus makes the fan quieter at lower speeds.

Of course, the power and the regulation for both of the fans is done by a very long, entirely sleeved in black 4-pin PWM cable and connector, which make the fans a very good choice for CPU cooling or boosting the airflow inside every modern case compatible with 140mm fans.

Also I would like to mention that even though both fans are rated to be working at 24V, they are capable of working at 12V, of course by providing only half of their maximum performance, which makes them suitable not only for industrial purposes but also for use in every personal computer by delivering lower noise level operation at half of the fans capabilities.

Apart from that, both fans are certified with IP67 water and dust protection for the motor and PCB, which are completely cast in special, highly heat conductive resin that combines thoroughgoing protection and effective motor heat dissipation. A feature which adds a nice industrial touch, which will guarantee a reliable operation and long life span of up to 150 000 hours.

With these components and features added to the fans they are capable to achieve:

  1. Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM – maximum of 3000 +/- 10% revolutions per minute with airflow level of 269,3 m³/h, static pressure level of 10,52 mm H₂O at noise level of 41,3 dB(A) powered with 24V. Rotation speed at 12V for this fan is about 1800 +/- 10% revolutions per minute.
  2. Noctua NF-A14 industrialPPC-24V-2000 IP67 PWM – maximum of 2000 +/- 10% revolutions per minute with airflow level of 182,5 m³/h, static pressure level of 4,18 mm H₂O at noise level of 31,5 dB(A) powered with 24V. Rotation speed at 12V for this fan is about 1100 +/- 10% revolutions per minute.

Both fans arrived with the same additional accessories packs, which includes:

  1. One set of four installation screws to attach the fans to a case fan slot
  2. 8 rubber pads, which should be attached to the corners of the fans for reducing the fan vibrations.

Since this is the IndustrialPPC series the guys from Noctua decided to provide only the basic accessories for industrial purposes.
I believe the time has arrived to mount the two fans on my test stand and check out how they will perform.

 

NOCTUA NF-A14 industrialPPC-24V-3000 IP67 AND NF-A14 industrialPPC-24V-2000 IP67 PWM TESTS

The tests will be conducted in my standard way. I will install the fans and test them at 5V/7V/9V/12V and my goal will be to check the performance of the products in real conditions. They will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the test can in no way be the same if the models are mounted on a cooler or on the case fan hole of any modern computer case. I will measure the amount of air going through the fans for one hour and their speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.
And this is what the fans look like installed on my test stand:

The test results are shown in the following charts:

The anemometer showed the following air speed passing through the propellers:

noctua-nf-a14-industrialppc-24v-3000-and-2000-s

After mounting the fans onto the stand, and leaving them to rotate for about 60 minutes at maximum speed, it was time for the tests to begin.

As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and both fans made at least one stable revolution at about 6.5V. To do my tests I had to decrease the operation voltage back to 5V and check their performance.

Test at 5V:

At the first test, which was conducted at exactly 5V, Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM was rotating at 780 revolutions per minute, providing airflow level of 48.48 cubic metres per hour, while Noctua NF-A14 industrialPPC-24V-2000 IP67 PWM was rotating at only 270 revolutions per minute with airflow level of 15.35 cubic metres per hour. Both fans were completely silent.

Test at 7V:

At the second test conducted at exactly 7V, Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM was rotating at 1125 revolutions per minute providing airflow level of 81.6 cubic metres per hour, while Noctua NF-A14 industrialPPC-24V-2000 IP67 PWM was providing 41.28 cubic metres per hour at 630 revolutions per minute. Again both of the fans were quiet.

Test at 9V:

At the third test conducted at 9V, Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM was delivering airflow level of 100.32 cubic metres per hour, while rotating at 1395 revolutions per minute. At the third test Noctua NF-A14 industrialPPC-24V-2000 IP67 PWM was providing 49.92 cubic metres per hour, while rotating at 825 revolutions per minute. At this test the first model started generating a tiny noise coming out of the propeller, while the second fan remained absolutely quiet.

Test at 12V:

At the last test conducted at 12V, both fans reached their maximum performance for this power voltage, which for Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM was airflow level of 140.64 cubic metres per hour at 1800 revolutions per minute, while for Noctua NF-A14 industrialPPC-24V-2000 IP67 PWM it was 70.08 cubic metres per hour, while rotating again at 1080 revolutions per minute. At this test the first fan became pretty noisy, while the second model remained absolutely quiet.

I believe the time has arrived to express my thoughts on both models.

 

NOCTUA NF-A14 industrialPPC-24V-3000 IP67 AND NF-A14 industrialPPC-24V-2000 IP67 PWM CONCLUSIONS

1. Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM and NF-A14 industrialPPC-24V-2000 IP67 PWM Performance:

By being part of the Noctua IndustrialPPC series, NF-A14 industrialPPC-24V-3000 IP67 PWM and NF-A14 industrialPPC-24V-2000 IP67 PWM are products entirely made to deliver high quality combined with the awesome addition of IP67 dust and water protection. Both products are designed following the very high Noctua standards to feature a wide range of technologies used together to deliver the best possible cooling performance in heavy duty environments. And not only, since they are also capable to operate at 12V.

Throughout the 12V tests, which I was able to perform both of the fans provided stable and very reliable airflow levels, while maintain middle to low noise levels which makes them a good choice for regular or enthusiastic customers who demand high airflow and high static pressure levels from the cooling fans to keep their machines working cool, stable and quiet for a long time. Thus this makes industrialPPC-24V-3000 IP67 PWM and NF-A14 industrialPPC-24V-2000 IP67 PWM a really good choice to be used as CPU cooler fans installed on a heat sink or water cooling radiator compatible with 140mm fans to keep every modern processor running cool and stable at default or overclocked frequencies.

In addition to that, the very long cable connected to the motors makes them a good choice for boosting the overall airflow inside any modern case equipped with 140mm fan slots. Of course, they should be set to operate at lower voltage, which will result in lower revolutions per minute and most of all at lower noise level.

For the extreme overclock achievements powering the fans with 24V will require external power source but will definitely provide outstanding cooling performance.

2. Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM and NF-A14 industrialPPC-24V-2000 IP67 PWM Appearance:

As I’ve already said several times in the past, the typical Noctua’s brown/pink colour scheme is not one of my favorite, but the black/brown colour scheme is something much better, more appropriate and more attractive. All of the models in the industrialPPC series feature the black/brown colour scheme, which will be much more neutral and will definitely fit in every modern case with entirely black interior.

I think Noctua NF-A14 industrialPPC-24V-3000 IP67 PWM and NF-A14 industrialPPC-24V-2000 IP67 PWM deserve the following reward:
