Blæser Noiseblocker BlackSilentPro P-1

The Noiseblocker BlackSilentPro P-1 is an 80 mm computer case fan engineered for quiet, continuous operation in desktop systems. Operating at 12 V with a maximum speed of 1500 RPM, this compact 80 x 80 x 25 mm fan provides targeted airflow for cooling components in small or mid-size enclosures while maintaining low acoustic output. Its black finish integrates unobtrusively into most builds and its lightweight construction simplifies installation in tight spaces.

Advantages

The fan combines a small footprint with a balance of airflow and low noise level, making it suitable where acoustic performance is important. The 1500 RPM maximum speed allows effective heat removal at moderate power consumption. The standard 80 mm diameter and 25 mm thickness ensure compatibility with common mounting points in PC cases, power supplies, or external brackets. The black color reduces visual distraction inside transparent or open chassis.

Suitable for

• Case cooling in compact desktop PCs
• Supplementary cooling for GPU or VRM areas with available 80 mm mounts
• Replacement fan for small form-factor power supplies with compatible dimensions
• Low-noise builds where reduced acoustic signature is required

Key specifications

• Fan diameter: 80 mm
• Dimensions (L×W×H): 80 × 80 × 25 mm
• Maximum rotational speed: 1500 RPM
• Rated voltage: 12 V
• Colour: Black
• Weight: 0.06 kg

How to use

Install the fan on any standard 80 mm mounting location in the case or device, aligning screw holes and securing with appropriate screws. Connect the fan's power lead to a suitable 12 V header on the motherboard, fan controller, or power source that matches the connector type provided. Ensure airflow direction matches the intended intake or exhaust configuration by checking the fan frame arrows or testing airflow after installation. Verify that the power source provides the correct voltage and that cabling is routed to avoid contact with the blades.

Recommendations

For optimal performance and minimal noise, mount the fan using rubber or vibration-dampening grommets when possible, keep the fan and surrounding area free of dust, and use a controlled fan curve or speed controller to limit maximum RPM during low-load operation.
