As you can see from the picture above, this sample also arrived in a similar packaging – a see through plastic box, through which you can see the fan structure, and a carton part covering the accessories, which I will discuss a bit later.
On the carton part on the front you can read the main characteristics of the product, while on the back you can read the technical characteristics of the model.
After looking at the box from outside, it is time to look at the fan in more detail:
The structure is a standard 120mm plastic frame, painted black, with an aluminium border forming a cylinder around the fan with the name of the company cut in.
And seen from the back:
The 9 blades are made from semi-transparent plastic and they have an interesting shape which looks a bit like bat wings. The propeller can be removed for cleaning. Unlike Enermax T.B.Vegas DUO, which I reviewed earlier, this model offers no backlight. According to Enermax, the fan provides 900 rounds per minute speed, 71.54 cubic metres per hour airflow and 11dBA noise. I will check soon if this is really the case.
Fan power and regulation is done via quite a long cable with a 3 Pin connector
The fan comes with the following accessories:
- Four metal screws
- 4-to-3 Pin power adaptor
The tests will be conducted in my standard way. I will mount the sample and test it at 5V/7V/9V/12V and my goal will be to check the authenticity of the technical characteristics given by the manufacturer. The product 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.
The test results are shown in the following charts:
Airflow through the fan at 5V, 7V, 9V, 12V.
Propeller rpm during the tests at 5V, 7V, 9V, 12V.
The anemometer showed the following airflow levels:
After mounting the fan to 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 test, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and the Enermax T.B.Silence made one full revolution at 3,6V. In order to conduct the first test I had to increase the voltage to 5V.
Test at 5V:
After leaving the fan to run at 5V for a while, I conducted the first test. The fan reached an airflow level of 32.64 cubic metres per hour at only 480 rpm. Of course we cannot talk about any noise at such speed.
Test at 7V:
The second test was conducted at 7V, where the fan reached a speed of 660rpm and an airflow level of 48 cubic metres per hour. Of course I didn’t expect to hear anything from the fan.
Test at 9V:
At 9V the fan reached a speed of 780 rpm and a airflow level of 59.04 cubic metres per hour. And again, Enermax T.B.Silence remained completely noise-free.
Test at 12V:
During the last test Enermax T.B.Silence reached a speed of 960 rpm, which is about 7% higher than the speed in the official technical characteristics and it offered a slightly better airflow level – 73.44 cubic metres per hour. There is absolutely no noise to speak of, even at a distance of less than 20 cm. It was simply as if the fan was not working at all.
After I took a look at the sample, it is time for me to give my personal opinion.
- Performance: On the whole, Enermax T.B.Silence offers quite a good performance for its modest rotation speed, which means that the fan is made for mounting on a case fan hole. I would not recommend it for cooling a CPU cooler, especially with an overclocked processor because the static pressure is not very high.
- Noise level: I don’t think there is anything to say here because most of the people who have handled a 120mm fan know that you almost cannot hear anything under a speed of 1000 rpm and with Enermax T.B.Silence you cannot hear anything at all.
- Vision: The model offers quite a pleasant and simple design. Nothing redundant or ornate. The frame is standard and the propeller’s blades have a slightly changed form for better performance.
The only disadvantage I could mention is the lack of PWM regulation, which could be completely unnecessary for this model.
I think Enermax T.B.Silence deserves the following reward:
The model has been added to the 120mm catalogue.
I thank Enermax for the sample!
