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 now 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 take over the better electronics (NB-EKA Plus) and the optimized bearings (NB-NanoSLI) from the Multiframe series. This enables an auto-restart function, a very low noise level and a very high life expectancy of 140,000 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). Connection is via 4-pin PWM.
This is the controllable PWM model with 92 mm size. Its speed is variable between 500 and 1,800 rpm, which makes a wide range between silent and power operation possible. At the same time, the fan generates only 3 dB (A), with a maximum throughput of 65 m³ / h.
