With the BlackSilentPRO series, Noiseblocker has added particularly well-equipped models to its range. These were developed in cooperation with the Hardwareluxx Portal Community and technically improved compared to the normal BlackSilent models. The BackSilentPRO thus becomes a high-end fan.

The frame and the fins are black. The Pro models also feature the optimal electronics (NB-EKA Plus) and the optimized bearings (NB-NanoSLI) of the Multiframe series. They are equipped with an automatic restart function, work quietly and have a very long service life of up to 100,000 hours.

The fan assembly has been optimized. The silicone frame effectively reduces operating noise. In addition, the frame is designed for use on radiators, where it offers optimum sealing in addition to decoupling. This prevents air from escaping through the minimal gap between fan and cooler and can no longer contribute to cooling.

The cables of this model have also been specially redesigned. 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, which achieves an extremely low volume of 10.7 dB(A). At the same time, the discharge volume is 20 m³/h.
