Fläkt Noiseblocker BlackSilentPro P-P

The Noiseblocker BlackSilentPro P-P is an 8 cm computer case fan designed to provide efficient airflow while maintaining low noise levels. Operating at 12 V with a variable rotational speed from 500 to 2000 RPM, this compact fan delivers an airflow of 54 m³/h and fits standard 80 mm mounting locations. The fan's black finish and slim 25 mm profile make it suitable for a wide range of PC builds and cooling arrangements.

Advantages

The fan combines a broad speed range with consistent airflow, enabling both quiet idle operation and higher-speed cooling when needed. Its compact 80 mm diameter and 25 mm thickness allow installation in tight or crowded areas of a case. The black colour and discreet design help the fan integrate visually into most systems while providing reliable air movement for case ventilation.

Suitable for

• General case ventilation in desktop PCs with 80 mm mounting points
• Small form-factor and compact builds where space is limited
• Noise-sensitive environments requiring quiet operation at low RPM
• Supplementary cooling for hard drive cages, VRMs, or chipset areas

Key specifications

• Fan diameter: 80 mm
• Thickness: 25 mm
• Operating voltage: 12 V
• Rotational speed range: 500–2000 RPM
• Airflow: 54 m³/h
• Product colour: Black

How to use

Mount the fan into an available 80 mm fan cutout in the case using the appropriate screws or anti-vibration fittings. Connect the fan to a compatible fan header or power source that provides 12 V and supports the desired control method (voltage or PWM control if supported by your system). Ensure airflow direction matches your intended ventilation path: typically intake at front or bottom, and exhaust at rear or top. Verify that the fan has sufficient clearance from cables and components to avoid interference with the blades.

Recommendations

For quiet operation, set the fan speed toward the lower end of the 500–2000 RPM range when thermal load is low; increase speed during heavy workloads to maintain adequate case airflow. Regularly check and clean the fan from dust to preserve performance and low noise levels. When combining multiple fans, balance intake and exhaust flow for optimal case ventilation.
