Sistema de arrefecimento para computador Zalman ZM-SF140A3 ventoinha para caixa de computador 14 cm preto 3 unid.

The Zalman ZM-SF140A3 is a 140 mm computer case fan designed to provide effective airflow for PC chassis and component cooling. It uses a fluid dynamic bearing to reduce operational noise and improve durability. With an operating voltage range from 5 to 12 V and a rotational speed range of 800–1500 RPM, this black fan balances airflow and acoustic performance for everyday and gaming systems.

Advantages

The fluid dynamic bearing ensures quieter operation and longer service life compared to basic sleeve bearings. The 140 mm diameter delivers greater airflow at lower speeds, helping to reduce noise while maintaining cooling efficiency. Its compact weight and standard form factor make the fan compatible with most cases and mounting locations that accept 140 mm fans. The simple black finish integrates unobtrusively into different builds.

Suitable for

• Case ventilation for desktop PCs
• Supplementary cooling for radiators or large heatsinks that accept 140 mm fans
• Replacement fan for quiet or budget-oriented builds

Key specifications

• Fan diameter: 140 mm
• Rotational speed: 800–1500 RPM
• Operating voltage: 5–12 V
• Bearing type: fluid dynamic bearing
• Colour: black
• Weight: 0.13 kg

How to use

Install the Zalman ZM-SF140A3 in a compatible 140 mm fan mount inside the PC chassis, aligning the airflow direction as required by your case design. Secure the fan with the appropriate screws or vibration-damping mounts, and connect it to a compatible fan header or power adapter that provides 5–12 V. Adjust fan speed via motherboard fan controls or an external controller to match desired cooling and acoustic balance.

Recommendations

For optimal results, position the fan to create a consistent airflow path through the case (for example, front intake or rear/top exhaust) and avoid obstructing the intake or exhaust grille. Periodically clean dust from the blades and bearing area to maintain performance and reduce noise over time.
