Noiseblocker BlackSilent Pro PK1 Fan - 140mm

Noiseblocker is the specialist for particularly quiet fans. To achieve this, the company relies on maximum quality with low manufacturing tolerances and high technological know-how with 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 now completes its portfolio with models featuring 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, but they stand out with a completely black design. The Pro models, on the other hand, adopt the better electronics (NB-EKA Plus) and the optimised bearings (NB-NanoSLI) from the Multiframe series. This enables an auto-restart function, very low noise development, and a very high lifespan of 180,000 hours.

The fan's mounting system is particularly sophisticated and minimises vibration transfer. A large silicone frame ensures reduced noise levels. Additionally, the frame is designed for use on radiators, where it not only decouples but also ensures optimal sealing. This prevents air from escaping through the minimal gap between the fan and the radiator, thus contributing to cooling.

Even with the cables, Noiseblocker has come up with something special. The sleeved 20cm cable can be extended with an included 50 cm cable (also sleeved). The connection is made via a 3-pin connector.

This is the ultra-silent model with a size of 140mm. Thanks to a low speed of 700 RPM, an extremely low noise level of just 9 dB(A) is achieved. The air volume transported is 49m³/h.
