To achieve this, the company relies on maximum quality with low manufacturing tolerances and high, technological know-how with German engineering. In addition, the manufacturer indicates that its technical specifications represent realistic values, which therefore can not be compared directly with other manufacturers.
With the BlackSilentPRO series, Noiseblocker completes its portfolio with models with particularly extensive features. They were developed in collaboration with the community of the Portal Hardwareluxx and compared to the normal BlackSilent models in addition to the accessories also technically improved. Thus, the BackSilentPRO mutate into high-end fans.
The shape of the frame and the fan blades they have in common with the normal BlackSilent, but are distinguished by a completely black design. By contrast, the Pro models adopt the better electronics (NB-EKA Plus II) and the optimized bearings (NB-NanoSLI) from the Multiframe series. This enables an auto-restart function, a very low noise level and a very long life expectancy of 160,000 hours.
The mounting system of the fan is particularly sophisticated and minimizes vibration transmission. A large silicone frame ensures a reduced volume. In addition, the frame has been designed for use on radiators where, in addition to decoupling, it ensures optimum sealing. This prevents air from escaping through the minimum gap between the fan and radiator and thus can no longer contribute to cooling.
Even with the cables Noiseblocker has come up with something special. Thus, the sleeved 20 cm cable can be extended by an enclosed 50 cm cable (also sleeved). The connection is made via 3-pin.
This is the Silent Model P-1 with 80 mm size. Thanks to a moderate speed of 1,500 rpm, a very low volume of 15.4 dB (A) is achieved. At the same time, the delivery volume is a good 29.3 m³ / h.
