Visual inspection

eLoop B12-P
The design of the eLoop B-12P model is unique due to its 6-blade design, the blades are joined together forming a ring. The blades of the fan are made out of white plastic, due to its structure the whole unit is solid.
The frame of the fan is black with white accents, also the structure of the frame is solid having no flex at all.

 

The back side of the fan uses 4 plastic beams to hold in place the blades & rotor of the fan.

 

The corners of the fans are rubberized for a more effective attenuation of possible vibrations.

 

The fan uses a 4 Pin Molex connector with PWM function. The connector is located very close to the frame of the fan for a better wire management.

 

BlackSilent Pro PK-PS

The design of the BlackSilent Pro PK-PS model is minimalistic; the fan uses 7 glossy dark brown blades.
The frame of the fan is black and very sturdy having no flex.

 

The back side of the fan is simple; the fan uses 4 plastic beams to hold the motor & blades in place.

 

The fan is powered using a 4-Pin Molex (PWM) connector. The connector is located very close to the frame of the fan for a better wire management.

 

Testing

The eLoop B12-P fan has been tested using a 240mm CPU liquid cooler: the SilverStone TD02 at maximum RPM.
The BlackSilent Pro PK-PS fan has been tested using a 280mm CPU liquid cooler: the NZXT Kraken X61 at maximum RPM.

The following system was used to test the fans:
Processor: Intel i5 4690K @ 3.9 GHz and overclocked to 4.5 GHz
Motherboard: MSI Z97 Gaming 9 ACK
RAM: 8GB Crucial Ballistix Tactical @ 2133MHz
GPU: MSI GeForce GTX 660 OC Gaming
SSD: Samsung 840 EVO 120GB
HDD: Samsung SpinPoint F3 500GB
PSU: Seasonic M12II-520 EVO Edition Bronze 520W
CPU: Cooler: SilverStone Tundra TD02/NZXT Kraken X61
Case: Phanteks Enthoo Luxe White
Display: AOC i2769VM
Thermal compound: Arctic Cooling MX-4

 

CPU Temp. – 140mm fans

 

 

CPU Temp. – 120mm fans

 

The noise level was measured at two RPMs and at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.

 

Final thoughts

eLoop B12-P
The eLoop B12-P model stands out due to its exceptional acoustic performance at 2000+ RPM. The 6 joined blades give the fan a unique look, its performance is also very good having no vibrations while having a good airflow.
The bionic eLoop fans are ideal to use with a radiator or a heatsink due to their high static pressure and excellent airflow, all this at a low noise level.
BlackSilent Pro PK-PS
The BlackSilent Pro PK-PS models offers exceptional performance with a minimalistic design. Like the eLoop series, the fans from the BlackSilentPro line are ideal to use on either a radiator or heatsink. Another feature of these fans is the rich accessory bundle, offering two cables with different lengths and a rubber frame to dampen any vibrations.
