To achieve this, the company focuses on maximum quality with low manufacturing tolerances and high technological expertise rooted in German engineering. Additionally, the manufacturer states that its technical specifications represent realistic values, which cannot be directly compared with those of other manufacturers. With the BlackSilentPRO series, Noiseblocker completes its portfolio with models that feature particularly extensive equipment. They were developed in collaboration with the community of the Hardwareluxx portal and have been technically improved compared to the standard BlackSilent models, in addition to the accessories. This transforms the BlackSilentPRO into high-end fans. The shape of the frame and the fan blades are shared with the standard BlackSilent models, but they stand out with a completely black design. The Pro models take the better electronics (NB-EKA Plus II) and optimized bearings (NB-NanoSLI) from the Multiframe series. This enables an auto-restart function, very low noise levels, and a very high lifespan of 100,000 hours. The fan's mounting system is particularly sophisticated and minimizes vibration transmission. A large silicone frame ensures reduced noise levels. Additionally, the frame is designed for use on radiators, where it provides optimal sealing in addition to decoupling. This prevents air from escaping through the minimal gap between the fan and radiator, ensuring it continues to contribute to cooling.
