Noctua is a brand that certainly does not send them to say in terms of build quality, longevity and reliability.

Today we have the pleasure of review together with the NF A12x25 Chromax Black swap: which in simple terms are the best fans on the market in the consumer range for the assembly of a PC from Gaming and not only!



After several years of development, the NF A12x25 have firmly entered the market like the best PC fans, at a price that is even over 30 euros per piece!

But is it true that these are the most efficient PC fans ever created? Is it worth spending these figures? Let's find out more in this article!

Noctua NF A12x25 • Box contents and assembly

The packaging of the NF A12x25 black swap chromax it is eye-catching and robust. Solid, with attention to every detail from an aesthetic point of view and then again from that of the gadgets contained within it.

The main feature of the chromax fans di Noctua is the color that distances itself from the classic and now iconic hazelnut color. This model is in fact nothing less than a black version of the classics NF A12x25, which came into the world several years ago.

Inside the package we find gods anti vibration pad built with criteria and that leave nothing to be desired from any point of view. In fact, we can also go and change the color of the last ones based on our build pc, choosing between: red, black, white, yellow, blue and green in addition to the gray already installed by default.



In the model we tested (Noctua NF-A12x25 PWM chromax.black.swap) we then find a extension cable 30, screws and an anti-vibration gasket.

The installation appears intuitive, as indeed any type of fan. For the sake of simplicity, we remind you that the air will come out from the rear side: the one with the label visible in the photos below.

Noctua NF A12x25 • Build quality

I find it at least necessary to dwell on constructive quality of this product, which undoubtedly also affects its weight.

These are the strongest and most solid fans I have ever had in my hands in years of experience in the world of reviews.

However, we are talking about a model that has won hundreds of awards and recognitions in its sector.

Noctua NF A12x25 • Technical specifications

Le NF-A12x25 chromax.black.swap they will come to your house with ben 6-year official Noctua warranty.

We had no doubts about reliability, but apparently Noctua is keen to make it clear to those who do not yet know the brand that their products are infallible and face hundreds and hundreds of tests before reaching the market.

Le technical specifications they leave some time they find if you are not particularly experienced. However, the few interested will certainly recognize promising and enviable numbers.

Unfortunately, we do not have the equipment advanced enough to conduct tests on the static pressure or on the airflow, in the next paragraph we will do some simple temperature tests using this set of fans!


Le NF-A12x25 fans operate at 2000 RPM maximum speed. In our tests we have seen these products exceed even i RPM 2200 without too many problems (fully loaded).

Noctua NF A12x25 • Test & performance

We have conducted test for several hours on multiple numbers of fans, using our Testbench with a Ryzen 3700x and an Arctic Freezer 34 Esports, using a single fan on it (controlled via PC).


The first graph shows us the average temperatures in full load (full load), when the fans were first set to 50%, then to 75% and 100% operating speed respectively.

As the duration of the test increased, we began to perceive more how much NF-A12x25 have an edge over other competitive models.

It is important to remember how the fans have label speed even very different from each other and therefore 50% of one will not coincide with 50% of another.

Le NF-A12x25 perform better than the other models tested, despite for example the Light Wings di Be Quiet operate at a speed of approx RPM 2500.

Noctua NF A12x25 • Comparison with competitive models

A further test we have carried out concerns a load in full load con AIDA64 Extreme, with increasing fan speed. In this test we kept the processor idle for 30 seconds, we then activated the stress test with the fans at 50% for 150 seconds, then at 75% and finally at 100% for the same duration.


In this type of test, the NF-A12x25 they seem to be going head to head with Light Wings high speed di Be Quiet, however if we had let the stress test run longer for a few more minutes, the comparison would have passed in favor of Noctua (as seen by the other graph above).

Noctua NF A12x25 • Comparison with competitive models

So how much can we say about NF-A12x25 is that they are fans offering performance and at the same time silent. In fact, it is not indifferent to sometimes perform better than a model that operates at a speed higher than well RPM 500.

Noctua NF A12x25 • General considerations

La versione chromax black of the NF-A12x25 has been kept waiting for several years. Finally we were able to test and review it as we would have liked to do.

We confirm every single word said so far: these fans they are currently 120 mm more performing on the market, with a noise ratio that is also quite low compared to the competition.

The only thing missing is lighting RGB, which unfortunately for some is a more important factor than performance. If you want to aim for a performing product equipped with RGB then the solution can be Be Quiet's High Speed ​​RGB Light Wings.

Otherwise, we would like to recommend these fans over any other model, if what you are looking for is only top performance.

The price is certainly not indifferent, since it almost touches the 33 euros per piece. Even the Arctic P120 can represent a valid alternative for those who have a smaller budget and do not want the top at all costs.
