## Long description

The Noiseblocker BlackSilentPro PK1 14 cm fan is a matte-black, low-speed case fan engineered for quiet PC cooling. With a frame reinforced by glass-fibre and a polycarbonate rotor, the fan delivers stable airflow up to 49 m³/h at a maximum speed of 700 RPM. The NB-EKA Plus II drive, NB-NanoSLI bearings and a low start voltage contribute to long service life and minimal operating noise. The compact dimensions (140 × 140 × 25 mm) and a 4.5 V low-voltage characteristic make this fan suitable for silent system builds.
Advantages
The BlackSilentPro PK1 combines a classical, robust chassis design with modern drive and bearing technology to ensure low impulse noise and reliable performance. Tool-free, vibration-free installation is enabled by the NB-Silentframe silicone seal and supplied mounting material. An extendable cable management system with combinable 20 cm and 50 cm plug-in cables simplifies routing, while reverse-pole and overload protection with an automatic restart function increase operational safety.
Suitable for
Silent desktop PC builds where low noise is a priority
Small form-factor cases compatible with 140 mm fans
Systems requiring long-life, low-maintenance cooling
