4. Visual inspection
The eLoop model well known due to the unique design of the 9 blades in the case of the 140mm variant, these are joined forming one stable ensemble. The blades are made out of white plastic and their texture makes them dust resistant. Also the blade ensemble design eliminates vibrations & oscillations and the noise produced by them.
Embossed in the center of the blades we find the “Bionic Loop” symbol.
The back side of the fan uses 4 plastic beams to hold in place the blades & rotor of the fan. Just like the blades, these beams do not use a regular design. In the center there is a label which presents the logo of the manufacture and the model of the fan. Also at the back the blades use a wave design.
The corners of the fans are rubberized for a more effective attenuation of possible vibrations.
The B14-PS model 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.
The B14-3 model is powered using a 3-Pin Molex connector.

5. Testing
The following system was used to test the fans:
– Processor: Intel i5 6600K @ 4.5GHz
– Motherboard: MSI Z170A Gaming M7
– RAM: Patriot Viper 8GB DDR4
– GPU: MSI GeForce GTX 970 Armor 2X 4G
– SSD: Samsung 840 EVO 120GB
– HDD: Samsung SpinPoint F3 500GB
– CPU Cooler: NZXT Kraken x61
– Thermal compound: Arctic MX-4
– Display: AOC i2769VM
– Case: Fractal Design Define R5
– OS: Windows 7 64-bit Service Pack 1
The fans have been tested using a 280mm CPU liquid cooler, the NZXT Kraken X61 at their maximum RPM.
CPU Temp. – 140mm 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.
6. Final thoughts
Just like the 120mm models, the B14-PS and B14-3 stand out thanks to their performance. Both models are silent even at their maximum speed generating at the same time a good air flow.
The Bionic design of the blades help dampen the vibrations and gives the fan a unique look with a solid construction. The build quality and the materials used are very good starting from the blade’s materials up to the frame and the rotor used.
The accessory bundle is rich including a complex mounting system, optimized for vibration dampening.
