## Long description

The Noiseblocker BlackSilentPro PK3 14 cm Black is a case fan engineered for steady airflow and low acoustic impact in desktop computer systems. With a 140 mm diameter and a maximum rotational speed of 1700 RPM, it provides an airflow rating of 153 m³/h while operating at a low nominal voltage of 4.5 V. The fan's matte black chassis and mirror-finish rotor present a restrained aesthetic that fits many builds, and its 140 × 140 × 25 mm footprint is compatible with standard case mounting points.
Advantages
The fan uses a glass fibre-reinforced chassis with an anti-dust polycarbonate rotor and a high-quality NB-EKA Plus II wide-range drive to keep impulse noise low. NB-NanoSLI bearings are specified for a long service life and very low running noise. An integrated cable management system with combinable plug-in cables (20 + 50 cm) enables tidy cable routing, while an NB-Silentframe silicone seal and included installation material allow vibration-free mounting without tools. Additional protection features include reverse-pole and overload protection plus an automatic restart function.
Suitable for
 Case cooling for desktop PCs requiring a 140 mm fan
 Quiet workstation and home office systems where low noise is important
 Systems that benefit from vibration-free, tool-less fan installation
 Builds needing stable, long-life fans with low start voltage

How to use

Ensure the airflow direction matches your case cooling layout and that power is supplied within the fan's specified voltage range.
Usage recommendations
For best acoustic performance, install the BlackSilentPro PK3 where unobstructed airflow is available and combine it with anti-vibration mounts or silicone seals supplied. Regularly check for dust buildup on the rotor and chassis and clean with low-pressure air to maintain airflow and low noise levels over the fan's service life.
