With the BlackSilentPRO series, Noiseblocker expands its offering with particularly well-equipped models. These have been developed in collaboration with the Hardwareluxx portal community and technically improved over the standard BlackSilent models. The BlackSilentPRO thus becomes a high-end fan.

The frame and blades are black. The Pro models feature optimal electronics (NB-EKA Plus) and optimized bearings (NB-NanoSLI) from the Multiframe series. They are equipped with an automatic restart function, operate quietly, and have an exceptionally long lifespan of up to 100,000 hours.

The fan assembly has been optimized. The silicone frame effectively reduces operating noise. Additionally, the frame is designed for use on radiators, where it provides not only decoupling but also optimal sealing. This prevents air from escaping through the minimal gap between the fan and the cooler, ensuring it contributes to cooling.

The cables of this model have also been specifically revised. The 20 cm long cable can be extended with the 50 cm long cable. The connection is made via 3 pins.

This is the Silent PR-1 model with a size of 60 mm and a moderate speed of 1,800 RPM, achieving an extremely low noise level of 10.7 dB(A). At the same time, the output volume is 20 m³/h.
