Hardware.Info - Noiseblocker NB-ELOOP 140mm 1400rpm
One of the best fans, the NB-ELOOP 140mm 1400RPM Noise Blocker, the PWM version also does not without merit - which had our complete round-up an award for its excellent efficiency, but it does so well at this point good
Tech-Legend - Noiseblocker eLoop B14-PS & eLoop B14-3
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.
Thermalbench - BLACKNOISE NB-ELOOP B14-PS AND B14-3 140MM FANS
They are among the quietest fans I have tested, and do wonders when up against low-med airflow restriction, preferably low. As such, they are one of the best fans from an airflow/noise basis here and definitely one to consider if you are ok with the 29mm thickness. If the price goes down eventually or a higher speed PWM version is available at a competitive price point, it will be one of favorite 140mm fans but it will have to contend with a recommendation for now.
