NoiseBlocker Bionic eLoop B12-3, B12-P and B12-4 review

NoiseBlocker Bionic eLoop series (S-Series) offers six 120mm different models:

  1. NoiseBlocker Bionic eLoop B12-1 – 800 revolutions per minute with airflow level of 57.3 cubic meters per hour
  2. NoiseBlocker Bionic eLoop B12-2 – 1300 revolutions per minute with airflow level of 86.9 cubic meters per hour
  3. NoiseBlocker Bionic eLoop B12-3 – 1900 revolutions per minute with airflow level of 121.2 cubic meters per hour
  4. NoiseBlocker Bionic eLoop B12-4 – 2400 revolutions per minute with airflow level of 150.3 cubic meters per hour
  5. NoiseBlocker Bionic eLoop B12-PS – 400-1500 revolutions per minute with airflow level of 98.7 cubic meters per hour
  6. NoiseBlocker Bionic eLoop B12-P – 800-2000 revolutions per minute with airflow level of 132.4 cubic meters per hour

Last week I received a huge package from Noiseblocker and inside of it there were 3 of the models from the Bionic eLoop series: NoiseBlocker Bionic eLoop B12-3, B12-4 and B12-P. I was so excited that I decided to start the article immediately.

All of them arrived in standard carton boxes in white and grey with a huge picture of the fan itself and some technical details on the front of the case. Of course, the full technical specifications and some facts related with the models are on the back of their packages.

Before I start with information about all 3 test samples I want to share some more details.

All of the models under NoiseBlocker Bionic eLoop series offer almost the same structure with minor differences and that is the way they are powered and regulated. The first four models are powered and regulated by a 3 pin connector and the other 2 are with a 4 pin PWM cable. All of the cables are very short but there are extenders inside the package.

I believe the most important thing is that NoiseBlocker Bionic eLoop series is developed and patented by Dr. Rudolf Bannasch and sponsored by the German Federal Ministry of  Economics and Technology.

So, let’s do something more than just writing words:

NoiseBlocker Bionic eLoop B12-3

As I already said, the full technical specifications are on the back of the box and I can say those features are really nice, and yes I will check them a bit later.

Let’s check out the fan itself.

After I took the fan out of the package I was like “WOW”. For first time in my life I saw a fan with such a futuristic and innovative design. Very nice and I hope very effective structure.

NoiseBlocker Bionic eLoop B12-3 offers a square 120mm plastic frame painted in black with holes in which the rubber dumpers in grey are installed to keep the fan without vibrations.

Apart from the let’s say almost standard plastic frame, the model is equiped with a very, very interesting propeller. The fan uses a glossy painted in white propeller offering six blades, with focusing the airflow channels on back of the blades and all of the blades are connected to each other with a cylinder on the outer edge. which is at 1mm distance from the cylinder of the frame. I guess this is used so they doesn’t brake while rotating at such a speed having in mind their thickness.

All I can say is -very, very interesting design.


Seen from the back:

Apart from the nice design, again we can see the usual cable system from NoiseBlocker, which is made of a very short cable coming out of the fan with 3 pin connector and after that every customer has the chance to choose how long a cable to use. There are two additional cable extenders added to the package with different length.

The standard package offers:

  1. 200mm cable extender
  2. 500mm cable extender
  3. 4 screws and 4 nuts
  4. 8 rubber dumpers for reducing the vibrations
And this is how the fan looks with the 200mm cable attached:

Now is the time to show what the mounting system should look like.


NoiseBlocker Bionic eLoop B12-P

As I said at the beginning of this test, all of the fans are almost the same, so I will point out just the differences between both models.

NoiseBlocker Bionic eLoop B12-P offers almost the same structure as NoiseBlocker Bionic eLoop B12-3 with a minor difference. The second model is equiped with a PWM feature and more precise fan control. As you can see at the official technical details, it offers a totally different work manner with different revolutions per minute and airflow range.

The standard package offers absolutely the same parts:

  1. 200mm cable extender
  2. 500mm cable extender
  3. 4 screws and 4 nuts
  4. 8 rubber dumpers for reducing the vibrations

NoiseBlocker Bionic eLoop B12-4

And last but not the least, here is the model with the highest revolutions per minute and the best airflow level from the series. And yes, visually  and as a package content it’s absolutelly the same like all of the models from this series. According to the technical details, NoiseBlocker Bionic eLoop B12-4 can reach up to 2400 revolutions per minute, which is quite impressive.

Seen from the back:

The standard package offers absolutely the same parts:

  1. 200mm cable extender
  2. 500mm cable extender
  3. 4 screws and 4 nuts
  4. 8 rubber dumpers for reducing the vibrations
Time for testing:
The tests for the 3 samples will be conducted in my standard way. I will mount NoiseBlocker Bionic eLoop B12-3, B12-P and B12-4 samples together and test them at 5V/7V/9V/12V and my goal will be to check the authenticity of the technical characteristics given by the manufacturer. 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 fans 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 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

Propellers rpm during the tests at 5V, 7V, 9V, 12V.

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

After mounting the fans onto the stand and leaving them 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 they made one full revolution at:

  1. NoiseBlocker Bionic eLoop B12-3 — 3.5V
  2. NoiseBlocker Bionic eLoop B12-P — 3V
  3. NoiseBlocker Bionic eLoop B12-4 — 3.5V

Test at 5V:

The starting voltage of all models is lower then the voltage for the first test, so I had to increase it to 5V. After I left them to reach their maximum performance the results were:

  1. NoiseBlocker Bionic eLoop B12-3 — reached 1020 revolutions per minute and airflow level of 63.36 cubic metres per hour.
  2. NoiseBlocker Bionic eLoop B12-P — reached only 615 revolutions per minute and airflow level of 32.16 cubic metres per hour.
  3. NoiseBlocker Bionic eLoop B12-4 — reached 1185 revolutions per minute and airflow level of 70.08 cubic metres per hour.

During the first test all of the models were silent.

Test at 7V:

The second test was at standard voltage of 7V.

  1. NoiseBlocker Bionic eLoop B12-3 — was rotating at 1350 revolutions per minute with airflow level of 77.28 cubic metres per hour.
  2. NoiseBlocker Bionic eLoop B12-P — was rotating at 1050 revolutions per minute and airflow level of 60.48 cubic metres per hour.
  3. NoiseBlocker Bionic eLoop B12-4 — was rotating at 1650 revolutions per minute and airflow level of 99.84 cubic metres per hour.

All of the fans got some really nice performance boost at 7V but only B12-P remained silent. From the other two test samples there was a noise from the air passing through the propellers.

Test at 9V:

The third test was at standard voltage of 9V.

  1. NoiseBlocker Bionic eLoop B12-3 — reached airflow level of 97.44 cubic metres per hour at 1590 revolutions per minute.
  2. NoiseBlocker Bionic eLoop B12-P — reached airflow level of 92.16 cubic metres per hour at 1575 revolutions per minute.
  3. NoiseBlocker Bionic eLoop B12-4 — reached airflow level of 123.36 cubic metres per hour at 2050 revolutions per minute.

The first two test samples got almost the same revolutions per minute and airflow and the noise started to be heard from a distance, but lower than 20cm. The third model was already noisy, a lot.

Test at 12V:

The last test was at standard voltage of 12V.

  1. NoiseBlocker Bionic eLoop B12-3 — reached its maximum airflow level of 117.6 cubic metres per hour at 11890 revolutions per minute.
  2. NoiseBlocker Bionic eLoop B12-P — reached its maximum airflow level of 123.36 cubic metres per hour at 2025 revolutions per minute.
  3. NoiseBlocker Bionic eLoop B12-4 — reached its maximum airflow level of 148.32 cubic metres per hour at 2420 revolutions per minute.

There was a noise from all of the fans, especially from B12-4. The other two were at normal level for those revolutions.


  1. Performance: Although all of the fans are from same series, all of them reached different airflow levels at different revolutions per minute. All I can say is that the whole series is very well balanced and offers 6 models working in totally different manners. There is one thing that drew my attention. During all tests the fans kept steady revolutions per minute with not much of variations, which speaks very well for the bionic engine. I want to point out the PWM model which started from very low revolutions per minute and ended the tests with really good results.
  2. Noise level: At the start of the tests all models were silent but at the other tests each one of them showed a different noise level at different revolutions at different voltage. All of them are noisy, I cannot say they are not but I can say with hand on my heart that all of them are much more quit than other models from other brands at same revolutions. Great job NoiseBlocker!
  3. Apperance:  All of the fans look like they are from the future. Very aggressive and at same time very stylish and innovative design. Let’s not forget the black/white/grey colour scheme that completes the fan really nicely.

Before I give the rewards I want to share some thoughts.

All of the models tested and reviewed in this article are suitable for installing everywhere inside a mini, middle, full or big tower case. Every single model I’ve tested can work and perform really well as a case fan or cooling a CPU cooler mounted on a processor working at normal or even overclocked frequency.

Really great job NoiseBlocker.

I think NoiseBlocker Bionic eLoop B12-3 deserves the following reward:

NoiseBlocker Bionic eLoop B12-P deserves the following reward:

and NoiseBlocker Bionic eLoop B12-4 deserves the following reward:

NoiseBlocker Bionic eLoop B12-3, B12-P and B12-4 have been added to the 120mm fans catalogue.

Official price (MSRP):

NoiseBlocker Bionic eLoop B12-3 – 16.99 euro

NoiseBlocker Bionic eLoop B12-4 – 16.99 euro

NoiseBlocker Bionic eLoop B12-P – 17.99 euro

I thank NoiseBlocker for the test samples.

    Well, the fastest member of the B12 family seems to be “broken” by default. It seems all of them are exceptionally noisy for 120mm fans after I’ve come across few other reviews and YT videos.
    And my decision was to skip them in favor of a 120x38mm Sunon which has a better quieter “sounding” for the given airflow, and was cheaper. You are right, a small motor tends to produce more noise when not perfectly balanced. So I opted for a more standard sized motor, where Sunons follow the efficiency and quality (I dare say), not the mere look.
    The balancing ring doesn’t seem to make things better for the fast B12-4 anyway. Its sound is produced by a poorly designed motor in my opinion.

  2. Reply Dk_vr 16.06.2013 at 15:08

    Well usually I don’t like a 120 or a 140mm fans with small motors because if they are not balanced properly they will get broken fast.

    Of course if there is a balancing ring added to the propeller it is other story and they can be trusted.

    Hi Dk_vr, thanks for your prompt response.
    Yes, I admit noone can guarantee that. Maybe I was just curious to hear something based on your hunch after being somehow engaged in the fans ‘business’ for a while.
    What is your opinion on the motor and its tiny size? I’ve always seemed to distrust big fans with too small motors like this one, I don’t know why… maybe it’s just … too small to continuously provide the power that carries out these big numbers.
    To put it this way – does the tiny motor size tell you something about its reliability over time? To me it was always an interesting subject I’ve never had the chance to discuss or ask someone who is more familiar with all this stuff.
    Thanks again.

    Hello Tedych and welcome.
    I am really happy that you enjoyed the article.

    Well I believe no one can guarantee that this fan will work in the same manner after few years 24/7.

    What I think?
    Well i think these fans are with very good build quality ( I can compare them with Noctua) and if I remember right they are a product of a lot of engineers and scientists from Technical University in Berlin sponsored by their government.

    I believe they will last for a long time and the warranty will cover if they fail 🙂

    Hi Dk_vr.
    I really enjoyed reading you review as I’m in the middle of choosing my next case fan to replace my dying Evercool.
    I’ll go with the 2400rpm model as it will allow both fan-controlled balance between silence and performance (in warm days), and top performance when it’s needed (hot summer) with its 75-80+ CFM.
    My concern is with the bearing longetivity in a 24/7 usage scenario. How do you think, can we trust it won’t let me down in the long run? Very inexpensive 2BB fans usually sustain 2+ years running continuously before they start to fail (gracefully), so I was hoping this would last for at least 4-5 years with no troubles.
    Now, almost one year after your review (and using the B12 series), what’s your opinion of these?

    Dear Dk_vr,

    I just confirned that my Aaus is compatible. Did not have notice the compatibility list, great stuff from their part.

    I’m going to have a look at the Megahalems.

    Once again thank you very much.

    Kind regards

    Hello Antonio,
    on Noctua web page there is compatibility list and there you can check which cooler is compatible with your motherboard.

    Good option is Prolimatech Megahalems with 2 push-pull fans like those I meantioned in few comments above.

    Best Regards

    Dear Dk_vr

    Thank you for the info. All fans seem very interesting, especially those with rpm control….

    As to the cooling solutions they also seem very good. Too bad the Noctua is maybe too large for my Asus P6T Deluxe V2. I’m assuming it will conflict with the ram heatsinks ( this is when I first built my PC, the only difference is that now I have a GTX 670 OC.

    Thank you very much for your expertise, it really helped me.

    Hello Antonie,
    no worries about the language…

    About the fans I meant that to go for high speed PWM models because when the ambient temperature is low then the motherboard will keep the fans running slow and quiet and when the ambient temperature is high then the motherboard will increase the speed and the system will continue to work without a problem.

    About the coolers…. Well I can recommend Noctua NH-D14, NH-C14, Prolimatech Megahalems, Thermalright SilverArrow SB-E Extreme and many others.
    Apart from that you can check some AIO watercoolings like CM Seidon 120m or 120XL or 240M, Antec Kuhler 920 and many more.

    Here you can see how Noctua NH-D14 looks inside HAF 932: and NH-C14 inside HAF 932: and CM Seidon 120M inside HAF 932: and Antec Kuhler 620 inside HAF 932:

    Now there are soo many options…

    Best Regards

    Dear Dk_vr

    First of all, I deeply regret misinterpreting your noble’s country nationality. For that, I apologise.

    Second, from what you have told me, non-PWM models would ensure an optimum airflow as they keep constantly pushing air at that speed?? or PWm would keep things under control.

    Third – I have a HAF 932 case and an Auss P6T Deluxe V2

    I run my i7 920 D0 2.66 @ 4.0 on air only. On idle I have 38-42 degrees Celsius and at full charge I get 68-74 max temperatures – actually only core 1 gets to 74, all other remain at 72 – I started with a 1.35V and I’m very slowly lowering it to manage less voltage and 100% stability. So far at 1.34 so good.

    Having said that, can you recommend me a heatsink+fan combo, price preferably under 150 euros. I need something effective and better than what I have now.

    Thank you so much in advance and thank you for all your testing. We appreciate.

    Regards from Portugal,

    Hello Antonio and welcome to our web page.

    1. Thanks for the good words and I hope we will be useful to you in the future.

    2. Since July 2012 all of the articles are written only in English. Apart from that all of the articles before that date are written in Bulgarian. And yes it is very similar to Russian since both of the countries use Cyrilic alphabet.

    3. Well I didn’t tested Thermalright ultra-120 eXtreme – 1366 RT Heatsink an I have no personal experience with it,but from what I saw it is a lovely cooler.

    About the fans: I believe you can boost the performance a bit but still don’t expect something special since this cooler is average model and no matter how many fans you will install still it cant reach the performance of a cooler which is twice bigger and twice more expensive.

    The performance picture of all fans I’ve tested so far is here:

    Anyway I can recommend you these models because they provide great airflow level and a serious noise when they are working at maximum voltage. Of course you will use them at max only when the ambient temperature is really high. Like this you will have nice and quiet running pc when is cool outside and the option to keep the pc cool when it is hot outside. Of course sacrificing the noise.

    1. Cooler Master Excalibur 120mm – a bit loud but with huge airflow at 2000 rpm. You will never see it rotating at 2000 if it is pwm controlled.
    2. Coolink SWiF2-120P 120mm – a bit loud but with huge airflow at 1700 rpm. You will never see it rotating at 1700 if it is pwm controlled.
    3. NoiseBlocker Bionic eLoop B12-P – a bit loud but with huge airflow at 2000 rpm. You will never see it rotating at 2000 it is pwm controlled.
    4. SilverStone FM121 – huge airflow at maximum speed and very loud but still can be controlled via the provided fan controller.

    Those are my favourite and actually the fans I use daily.

  12. Reply Antonio 28.03.2013 at 3:31

    First of all, congrats for the great site and reviews, they are truly amazing and accurate.

    Secondly, I’m actually looking for a fan for my Thermalright ultra-120 eXtreme – 1366 RT Heatsink, the fan that came with is is silent and efficient. On a i7 920 @ 4.0 on air, I get

    temps of about 68-72 degrees while playing BF3 (most demanding game so far) with everything maxed out. My actual fan has 67 CFM air flow and I am looking for a new one to go along

    with the heatskink that could lower the temps in about 5-8 degrees (if possible). Noise really matters to me but I am whiling to make a compromise. Can you recommend or point me in the right direction for

    a pwm or non-pwm fan that should have at least an airflow over 80 CFM, good or optimal air pressure and a really god ratio performance/noise or even just performance (pwm?). Mine runs always at 1534 rpm (3-pin), I consider it non-

    intrusive in terms of noise.

    I have no idea of people ask for you advice a lot but I just found your tests/review page and I was blown away by the way you guys test the fans and the accuracy you guys put into the tests really impressed me.

    I had no idea how some fan specs just don’t match with the manufacturer specs, that is why I highly regard your tests. They can be trusted!!! This is the reason I’m asking for your advice. Would you recommend any of the above or another???

    Regards from an avid reader of your fan reviews (can’t read what I’m assuming to be Russian??? XD)

    Very interesting propeller design. I wonder is this desing good enough to compare with the standart fans with equal airflow and are these NBs more silent then the usual fans.

  14. Reply Boskorp 10.10.2012 at 14:08

    Yeah they look really nice, like’em all. NoiseBlocker always have good package contents, so You don’t look buying anything else. Can you pls provide some additional photo/video of fan spinning, as I want to see if the marvellous design matters during worktime or it fades away in the spin? Good review, plenty of info, 10x

I have the feeling the price will not be very satisfying for most people but to be hones if the launch 140mm models I will consider buying 3/4 for my case as they look AMAZING. 🙂 Keep up with the great extensive reviews Dobrin, it will be rewarded someday. 🙂 Massive thumbs up.
