Nanoxia Deep Silence 140mm 1.800 U/min – Test and Review

After I spent some time having fun with Nanoxia Deep Silence 120 mm – 1.800 U/min, which really impressed me with its performance, now it is time to pay some attention to its bigger brother from the Nanoxia Deep Silence series.

Nanoxia Deep Silence 140 mm – 1.800 U/min arrived to me for a test and review in a pretty standard package for all of the fans in the company portfolio – made of carton, painted in white, black, yellow and green with some technical details regarding the product and a big see-through cut on the front panel, through which we can see the propeller structure, the frame and the propeller colours.

As usual all of the technical details regarding the product are located on the back of the package in several languages. As you can see from the picture above the rated performance is very impressive and to be honest I am pretty eager to check how this fan will perform. But before I test the fan, let’s check its structure.

And this is what the fan looks like out of its package

After I spent a minute or two looking at the fan, I noticed that Nanoxia Deep Silence 140 mm – 1.800 U/min offers a pretty standard for the series fan structure featuring:

  1. A square semi-transparent painted in black matte frame with dimensions of 140 x 140 x 25mm. The frame itself is made to be installed on a 140mm case fan slot or on a CPU cooler supporting fans up to 140mm.
  2. A propeller made of semi-transparent plastic painted in the typical for the company dark green colour with 9 not very wide but still very aggressively angled blades, made entirely to provide maximum airflow level combined with static level pressure which is as high as possible.
  3. The connection between the frame and the propeller is done by bearing, which should provide stable work at up to 80.000h and is powered and regulated by a 440mm 3- pin cable sleeved in black mesh and a connector.

The standard Nanoxia Deep Silence 140 mm – 1.800 U/min package features:

  1. 4 metal screws
  2. 4 rubber dumpers painted in dark green colour
  3. a 7 volt adapter cable

After I spent some time describing the fan, I believe it is time to check how it will perform.

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 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.

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 passing through the propeller:

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 Nanoxia Deep Silence 140 mm – 1.800 U/min made at least one full revolution at exactly 5V.

Test at 5V:

At the first test conducted at 5V, Nanoxia Deep Silence 140 mm – 1.800 U/min reached up to  1020 revolutions per minute, providing airflow level of 74.88 cubic metres per hour. At this test the fan was completely silent even from a distance lower than 20cm.

Test at 7V:

At the second test conducted at 7V, the fan slightly increased its airflow level up to 99.84 cubic metres per hour, while operating at about 1275 revolutions per minute. At this test the fan started generating a tiny noise coming out of the air passing through the propeller.

Test at 9V:

The third test conducted at 9V, made Nanoxia Deep Silence 140 mm – 1.800 U/min work at 1515 revolutions per minute providing airflow of 118.56 cubic metres per hour. At this test the noise increased.

Test at 12V:

At the last test conducted at 12V, the fan reached its maximum performance providing airflow level of 142.86 cubic metres per hour, rotating at 1830 revolutions per minute. At the final test, the fan was a bit noisy, which is actually normal for such a performance.

I believe  I am done testing and it is time to share my conclusions:

Performance:

As part of the Nanoxia Deep Silence series, the 140 mm – 1.800 U/min offers a pretty standard fan structure, which is actually the same for all of the 120mm and 140mm models. A performance fan structure made to provide as much as possible airflow, combined with pretty nice static level pressure, unfortunately this design is a bit noisy. Because of this I can recommend this fan to be used as a case fan boosting the overall airflow inside the case using the 7V adapter included in the package or as a fan installed on a bigger CPU cooler to provide nice and stable cooling performance for a processor working at default or overclocked frequencies.

Appearance:

Since I have already seen this design I can say that green is not really one of my favourite colours for a PC component and still somehow this one looks very attractive. Apart from that, the overall appearance of the fan is really aggressive looking with the very sharp-angled blades of the propeller. 

I think Nanoxia Deep Silence 140 mm – 1.800 U/min deserves the following reward:

I thank Nanoxia for the test sample.
