Antec TrueQuiet Pro 120 Test and Review

The first models of Antec TrueQuiet series was released back in May 2012 with dimensions 120 and 140mm as a revolutionary fan with black/yellow colour scheme and since then there have been a few modifications already released all over the world. For this test and review I got Antec TrueQuiet Pro 120 with black/grey colour scheme offering a few very interesting and unique features. Features that made me really eager to do this test and review almost immediately after I got the test sample.


The model was provided to me in a very simple but still elegant transparent plastic box holding the fan in the middle and providing the opportunity to check the fan itself before purchasing and a carton cover hiding the additional accessories and providing some technical details which could be seen from the front, some additional details on the back and full technical details on the side panel of the package.


And at the first moment I saw the package I noticed something that made me smile, and that is the structure of the fan.


Antec TrueQuiet Pro 120 attracted me with it’s futuristic appearance and sharp edges but this is only part of the full picture. The Antec TrueQuiet Pro 120 structure is kinda unique and here is the first interesting feature for this product, namely the frame.


Actually there isn’t a typical fan frame but there is a thin plastic frame behind the propeller holding the motor. Antec TrueQuiet Pro 120 back frame is made of very hard plastic without a board around the propeller but still there is a space where the screws or the rubber dumpers can be installed when mounting the fan on a CPU cooler or a case fan slot. And of course there are preinstalled rubber dumpers on both sides to reduce the vibrations if there are any when the fan is installed.


If you watched closely you probably already saw 3 more interesting features. First thing is the very futuristic and a bit aggresive propeller offering 7 very sharp blades with a balancing cylinder on the edge fully open from everywhere. That is a bit risky idea because if there is a contact with the propeller when rotating it can brake easily but still there are almost 0 vibrations just because of this idea. I can say, good job Antec!

The next thing that I think I should meantion is the very small motor. Like this the propeller surface is much bigger and providing much more airflow, while operating at lower revolutions per minute. Very nice feature which I saw in some other models from other brands. Nothing new but still very effective.


And the last for now is the wiring. Actually, there are 2 preinstalled and unremovable pairs of cables. One of them is the typical 3-pin power cable and connector sleeved in black, while the other is a small switch with options LOW and HIGH. Yes, that is right… with this switch the fan could be limited to work at low revolutions per minute, namely 600 revolutions per minute. I am wondering why there is such a feature since the fan is working at max 1200 revolutions per minute and in fact this is the quiet operation for most of the 120mm fans. Anyway, for the tests I will switch to HIGH mode.


I believe now is the time to mention that the fan can be powered directly from a power supply with this 4-pin molex to 3-pin adapter which offers a separate tachometer cable that could be attached to the motherboard directly. Cute…


The standard package offers:

  1. 5 rubber dumpers, seems one is a spare
  2. 4-pin molex to 3-pin connectors fan adapter

So far so good. I saw some of its main features and I believe it is time to do some testing. I heard there is one more unique feature but for this…. a bit later.

The tests will be conducted in my standard way. I will mount the fan and test it at 5V/7V/9V/12V and my goal will be to check the performance of the fan in real conditions. The products 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 fan is 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 fan for one hour and its 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 fan looks like installed on my test stand:


The test results are shown in the following charts:

The anemometer showed the following air speed:

After mounting the fan onto the stand and leaving it to run for about 30 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 the Antec TrueQuiet Pro 120 made one full revolution at 4.5V and to conduct the first test I had to continue increasing the voltage to 5V.

Test at 5V:

The fan was rotating in a stable way with 570 revolutions per minute offering an airflow level of 31.2 cubic metres per hour. Of course, at this operating voltage it was completely silent.

Test at 7V:

The second test, conducted at 7V made the fan rotate with 780 revolutions per minute and airflow level of 46.08 cubic metres per hour. Again the fan was completely silent.

Test at 9V:

The third test was conducted at 9V and here Antec TrueQuiet Pro 120 reached 975 revolutions per minute and maximum airflow level of 57.84 cubic metres per hour. Again the model remained silent.

Test at 12V:

The last test was conducted at 12V where the model reached its maximum performance with airflow level of 72.96 cubic metres per hour at exactly 1200 revolutions per minute. The fan was still silent.

So far so good. I was done testing and when I shut down my power supply so I can remove the fan from the stand and put it back to his original state I noticed the last interesting feature for this product. When the power was down the fan remained rotating slowly reducing the revolutions per minute and about 20-30 seconds later it went off completely. Very, very nice feature to continue moving the air even when there is no power. I can say very useful feature.

And here is a small demonstration done by Antec:


  1. Performance: All I can say about Antec TrueQuiet Pro 120 is that it is a wonderful fan offering great features and a very decent performance when operating at 9 and 12V. This model is made to work at 5-12V range and for that reason I can recommend it to be used as a case fan supporting the airflow inside the case or a CPU cooler fan cooling a processor working at default or a bit overclocked frequencies but I can’t advise anybody to use it when the processor is with higher overclock frequencies. It just lacks revolutions per minute, suficient airflow level and static pressure.
  2. Noise level: The model was rotating at maximum 1200 revolutions per minute and was completely silent in all tests. As probably many of you know 1200 revolutions is the step where the 120mm fans start to get a bit noisy.
  3. Apperance:  Awesome visual appearance done by very aggresive and futuristic design offering a stylish black/grey colour scheme.

I think Antec TrueQuiet Pro 120 deserves the following reward:


Antec TrueQuiet Pro 120 has been added to the 120mm fans catalogue.

I thank Antec for the sample.
