Ventoinha Noiseblocker BlackSilentFan X1

The Noiseblocker BlackSilentFan X1 is an 8 cm computer case fan engineered for quiet and reliable cooling. With a compact 80 × 80 × 25 mm frame and a maximum speed of 1300 RPM, it delivers up to 26 m³/h airflow while operating at 5 V. The fan uses a glass fibre-reinforced chassis and an anti-dust polycarbonate rotor, offering a balance of durability and low noise suitable for noise-sensitive systems.

Advantages

This model combines low cost with high build quality. It features a stable, glass fibre-reinforced chassis, an anti-dust polycarbonate rotor, an extra-long connection cable, and includes four mounting screws. The fan has an extremely low start voltage and a low-impulse NB-EKAPlus II wide-range drive. Built-in reverse-polarity and overload protection with an automatic restart function improve operational safety, and extremely quiet bearings reduce operational noise.

Suitable for

• Cooling compact computer cases and small form-factor PCs
• Replacements for standard 80 mm case fans
• Quiet home or office systems where low noise is required
• Applications requiring a reliable, low-voltage fan (5 V operation)

How to use

Install the fan into an 80 mm mounting position in your computer case using the supplied screws. Connect the fan to a 5 V fan header or power source compatible with its connector. Ensure correct polarity on connection; the fan's built-in protection guards against reverse polarity but correct wiring is recommended. Position the fan so that airflow direction matches your cooling layout and verify secure mounting to minimize vibration.

Recommendations

For lowest noise and longest bearing life, operate the fan on a stable 5 V supply and avoid obstructing the rotor. Periodically clean dust from the polycarbonate rotor and chassis to maintain airflow and performance. When replacing an existing 80 mm fan, check connector compatibility and mounting hole alignment before final installation.
