Noiseblocker is the specialist in particularly quiet fans. In order to achieve this, the company relies on maximum quality with low manufacturing tolerances and a high level of technological know-how with German engineering. In addition, the manufacturer also states that their technical specifications represent realistic values, which therefore cannot be compared with other manufacturers.
The BlackSilentPRO series completes Noiseblocker’s portfolio with a range of models with extensive equipment. They have been developed in conjunction with the Hardwareluxx portal community, and as well as the accessories, they have been enhanced technically in comparison with the normal BlackSilent models. This means the BackSilentPROs have mutated into high-end fans.
The design of the frame and the fan blades is the same as the normal BlackSilent, but the completely black design makes them different. However, the Pro models take the enhanced electronics (NB-EKA Plus) and the optimised bearing (NB-NanoSLI) from the Multiframe series. This facilitates an auto-restart -function, very low-noise operation and a very high life expectancy of 180,000 hours.
The fan’s mounting system is particularly sophisticated and minimises transmission of vibrations. A large silicone frame ensures reduced volume. In addition, the frame has been designed for use of radiators, meaning it delivers optimal insulation as well as decoupling. This stops air leaking above the small gap between the fan and radiator where it can no longer help to cool.
Noiseblocker has even come up with something special for the cables. So the sleeved 20 cm cable can be extended using an accompanying 50-cm cable (also sleeved). Connection is via a 3-pin connector.
This is the 120-mm Ultra-Silent model. Thanks to a moderate speed of 900 rpm, it achieves a very low noise level of 11 dB(A). At the same time, airflow is a good 68 m³/h.
