Just in time for the holidays, we get a very big package containing the whole series of eLOOP and Multiframe fans from ((( Noiseblocker ))). And one Black Silent Pro 140 mm PWM fan which we will cover in a future review.

In our first review we covered almost all PWM variants from them, today we will focus primarily on the 3 pin / non-PWM ones.


The usual prolog


(((Noiseblocker))) is a trademark of the Blacknoise group.
Blacknoise Deutschland GmbH is focused on the development and production of high-quality product solutions in computer Hardware, multimedia accessories and they also produce industrial grade fans.

Founded in 1998, they are the European leader in the low-noise PC arena – particularly through their Noiseblocker brand – and have become a mature, economically stable company.
Thus, they have branches worldwide in over 33 countries.

Their success is based on innovative product development, quality assurance and not only their global reach, but their ability to think flexibly and are very proud of their products, patented technologies and testing methodology like low-noise development, Low-dB-measuring chamber, fast prototyping, CAD construction, fan-characteristic curve-testing bench-measurement and acoustic-camera-visualization engineered at the limits of audibility.

Complete Specifications:




Very interesting fact regarding the Bionic eLOOP series is that they were developed and patented by Dr. Rudolf Bannasch and sponsored by the German Federal Ministry of Economics and Technology.


160.000 hours – that’s over 18 years!
And all have 6 years warranty!


Visual Inspection



All eLOOPs 3 pin and 4 pin are the same in every aspect from the box, content and design, besides the specs of course.





Then another thing that makes the eLOOP unique is that it has a continuous blade design.


Again the attention to details is everywhere, including the bundled accessories that are complete for any scenario, with sleeved modular cables and even you can choose between a short one (22,5 mm) and a long one (51,5) or just combine them for extra length.
We also like options so another plus goes here.

Moving to the Multiframes.

The same as above, up until now, they started to make revisions to some of them.
We got one such example, the M12-3 is now the S3 V1.01.
Has a new box design, with a clear window and easier to remove the content.
The content is the same and we have a new sticker on the fan.



The rest of the Multiframes, nothing has changed since our PWM variant.



Their famous modular frame design, a very effective anti vibration method.


If that wasn’t enough, it comes with an anti-vibration outer silicon gasket, for example, when you want to use the fan on a heatsink and/or case, radiators etc.
The Multiframes have a non removable cable ~ 50 cm in length with the same high quality sleeve.


How we tested


– Sound meter – Pyle PSPL01 – positioned 1 meter from the case, (we will include +/- 2-3 % margin for error) with ambient noise level of 25-30 dB/A.
– RPM control and monitoring via MSI Control center, tested at 4 different stages 20, 50, 80 and 100 % RPM load.

– We removed the video card plus our PSU has semifanless action so that we removed virtually any other sources of sound, to leave only the Noiseblocker fans running for optimal testing.

– Regarding airflow we used an anemometer – Mastech MS6252A (we will include +/- 6-11 % margin for error) – positioned 15 cm away from the fan and in between we use an improved cardboard tubing also in diameter of 120 mm to channel all the airflow as straight as possible (used also for the small fans). The results were recorded in CFM.

– The rest of the hardware:
Processor: Intel i7 2700k @ stock settings
CPU heatsink: Thermalright AXP-100R
Case: NCase M1
Storage: Samsung 840 Evo (no HDD, again to remove all noise)
Motherboard: MSI B75IA-E33 mITX
PSU: Silverstone SX-600G SFX w/ semifanless function

– Other fan(s):
DeepCool GamerSotrm GF120 – 500-1800 RPM PWM – up to 33 dB/s and ~ 80 CFM
Scythe S-Flex – 1600 RPM 3 pin – 42 dB/a and ~ 60 CFM

The results.


With previous impeccable track record, we had high expectations for the 3 pin variants as well and to see if anything has changed in the mean time.



As you can see, all is good, impressive numbers yet again.

The B12-4 is the most powerful we ever tested but also the loudest.
The B12-1,2 and M12-1,2 are dead silent, you barely notice that they are running.
The B12-3 and M12-3 with an excellent middle ground regarding performance and noise.

And the PWM ones, the B12-PS and M12-PS again with impressive results in all areas, not that loud compared to the top PWM ones, the B12-P and M12-P respectively, so they make excellent all rounders for almost every scenario.

*23.09.16 Update: we used these in a watercooling & overclocking project build.

The hardware:

Processor: Intel i7 6700k @ Various GHz and Voltages
Case: Phanteks Enthoo Primo White Special Edition E-ATX
SSD: 2x Samsung 850 Pro 256 GB
HDD: 3x Seagate ST Series (3+4+5 TB)
Motherboard: ASUS ROG Maximus Hero VIII Z170 ATX
RAM: 64 GB (4×16) AVEXIR Core Series DDR4 2400 Mhz C16 GREEN LED
PSU: Corsair AX1200i Platinum
Cable Extensions: CableMod ModeFlex C-Series Green
Sound Card: Asus Xonar D2X
Video Card: KFA2 GTX 970 EXOC Black Edition
Video Card: NVIDIA Titan X Pascal
Fan Controller: Reeven Six Eyes II RFC-02
Fans: 10x Noiseblocker B12-PS

WC Components:
– 1x 480 Hardware Labs Black Ice GTX Gen II Extreme Water Block
– 1x DeepCool Maelstrom 120 MM AIO
– 1x Cooler Master AIO Eisberg 240L Prestige


– Corsair Link v4.3.0.154
– CPU-Z v1.76 ROG Skin
– Prime95 v28.9
– Core Temp v1.2





With the stock 120 mm vent from the Deep Cool Maelstrom (temporary cpu cooler as seen above), the i7 6700k at 4.5 ghz with 1.251v had:


Then we replaced the 120 mm fan from the Deep Cool with one 120 mm Noiseblocker Eloop B12-PS.
We noticed a drop in temperature of 4-5 degrees.

But paired with 2x Noiseblocker fans in a pus and pull configuration, we managed around 8-10 degrees drop in temperature.

Stay tuned for the completed build and more results !

* Update: 16.10.16

We sourced a Cooler Master AIO Eisberg 240L Prestige and we linked its AIO Pump to the 480 Hardware Labs Black Ice GTX Gen II Extreme waterblock, along side the 2x Noiseblocker B12-PS 120 mm fans in a push-pull configuration (4 by 4).


And these are the new results so far:

The i7 6700k OC-ed at 4.5 Ghz with 1.251v


The i7 6700k OC-ed at 4.8 Ghz with 1.373v


Thanks to the new block and especially the Noiseblocker B12-PS fans, this is the only time we manged to get 4.8 Ghz of our CPU !
Not to mention the extra 10-15 degrees in average temperature reduction at 4.5 ghz !

We will take everything to the next level with a custom loop as well. Stay tuned!

* Update: 02.01.17

A new video card as been added, the Mighty Titan X Pascal.




– New CPU Block in plans
– The Titan X really needs WC

So yeah, 2017 should be really interesting.



The good:

+ They perform flawlessly
+ One of the best quality/performance and noise ratios, especially the 3 pin versions
+ The PWM ones have a smooth rpm transition
+ The attention to details is outstanding
+ The antivibration systems work extremely well
+ Both series look so advanced and cool
+ Their presentation is very professional and rich with technical details
+ Complete accessories bundle
+ Nice new and comfortable box design for the revision of the Multiframe

The bad:

– Maximum RPM for the eLOOP and Multiframe may be subjectively judged
– The B12-4 is loud.
– The new box design is nice but they removed the rich technical details on the back, now they have only the basics
– Maybe the price for some but our motto is if the only compromise is price and in return you get maximum everything, then it’s well worth it.

Nothing has changed in build quality or performance since our last review, so:

Globetrotters “Dead Silent” Award – 5 out of 5 – for B12-1, B12-2, M12-1 and M12-2


Globetrotters “High Performance and Silent Ratio” Award – 5 out of 5 – for the B12-PS and M12-PS PWM


Globetrotters “Excellent balance power/silent operation” Award – 4.5 out of 5 – for the B12-3 and M12-S3


Globetrotters “Maximum Performance” Award – 4 out of 5 – for the B12-4


Many thanks to Noiseblocker for the supplied products !
