## Long description

NoiseBlocker BlackSilentPro PL1 120 mm is a low-noise case fan designed for general PC ventilation. The fan has a 120×120×25 mm frame, a black finish and an anti-dust polycarbonate rotor that works with a reinforced glass-fibre chassis. It operates at up to 900 RPM, produces approximately 11 dB acoustic level at its specified operating condition and moves up to 68 m³/h of air at 4.5 V. The unit includes an extendable cable management system and is supplied with a silicone seal and installation material to support vibration-free assembly.
Advantages
The fan combines a classic matte-black design with a mirror-finish rotor and a stable, glass fibre-reinforced chassis for durable, low-vibration operation. A wide-range drive and low-noise bearing technology give a low acoustic signature and long service life. Cable management with combinable plug-in leads and tool-free installation capability simplify routing and mounting in compact or standard PC cases.
Suitable for
General case ventilation in desktop towers and small form-factor builds
Intake or exhaust fan positions to improve airflow across components
Quiet systems where low acoustic output is required
Systems that benefit from vibration-damped, tool-free installation

How to use
Install the NoiseBlocker BlackSilentPro PL1 in a compatible 120 mm fan mount using the supplied silicone seal and installation material to achieve a vibration-damped fit. Connect the fan to an appropriate fan header or controller that supports the operating voltage; the fan is specified to move rated airflow at 4.5 V and will run up to 900 RPM at its maximum input. Route and combine the supplied plug-in cables as needed for neat cable management and secure electrical connection before powering the system.
Usage recommendations
For quiet operation, place the fan in intake or exhaust positions that promote a direct airflow path across heat-generating components and avoid obstructing the rotor. Ensure the fan header or controller can supply the required voltage range and check for secure, vibration-isolating mounting to preserve low noise performance and long bearing life.
