Noiseblocker is the specialist in particularly quiet fans. In order to maintain this status, the company relies on maximum quality with low manufacturing tolerances and a high level of technological know-how with German engineering. The manufacturer also takes pride in the fact that its technical specifications represent realistic values, which cannot therefore be compared directly with other manufacturers.
The BlackSilentPRO series completes Noiseblocker’s portfolio with a range of models featuring particularly extensive equipment. They have been developed in conjunction with the Hardwareluxx portal community, and, as well as the accessories, have also 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 140,000 hours.
The fan’s mounting system is particularly sophisticated and minimises transmission of vibrations. A large silicone frame ensures reduced volume. The frame has also been designed for use on radiators, meaning it delivers optimal insulation as well as decoupling. This stops air leaking through 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. This means that the sleeved 20-cm cable can be extended using an accompanying 50-cm cable (also sleeved). The connection is made via 4-pin.
This is therefore a controllable PWM fan in the 120 format. The speed can be varied from 600 to 1500 rpm, thus providing a large bandwidth between Silent and Power mode. The fan generates only a minimal 8 dB(A), and a maximum throughput of 100 m³/h.
