ADDA 4cm (4020) 12V High-Speed Silent Case Fan – JPD0402012MA3A11 Computer Cabinet Power Fan with Hydro Bearing, Speed Measurement (RPM Lead), and Small 3-Pin Connector

Product Description

Ensure optimal cooling for your compact electronics with the ADDA 4cm 4020 12V Silent Fan. This high-performance cooling solution is specifically designed for computer cabinets, power supplies, and industrial enclosures where space is at a premium. At Robogears, we recommend the JPD0402012MA3A11 model for its advanced Hydro Bearing technology, which provides a significantly longer lifespan and quieter operation compared to standard sleeve bearings. With a high rotational speed of 6500 RPM, this fan delivers a powerful airflow-to-size ratio, effectively dissipating heat from critical components. The integrated small 3-pin plug includes a dedicated speed measurement (RPM) lead, allowing your motherboard or controller to monitor fan health and performance in real-time at your Pimpri facility.

Detailed Key Features

• High-Speed Thermal Management: Operates at a powerful 6500 RPM, providing maximum heat extraction for small-form-factor devices and server components.

• Advanced Hydro Bearing Technology: Features a self-lubricating hydro bearing that reduces friction, lowers noise levels, and extends the MTBF (Mean Time Between Failures).

• Real-Time Speed Measurement: Includes a 3rd wire (RPM lead) for precise speed monitoring, ensuring you can detect a cooling failure before it affects your hardware.

• Industrial Build Quality: Manufactured by ADDA, a leader in thermal solutions, ensuring reliability for 24/7 continuous operation in professional environments.

• Efficient Power Profile: Draws only 0.20A (2.4W), making it an energy-efficient choice for multi-fan cooling arrays in networking equipment and power supplies.

Prototyping & Engineering Tips (Robogears Exclusive)

• Mounting Orientation: At your Pimpri workshop, ensure the fan is mounted with the ADDA label facing the direction you want the air to blow. This fan is optimized for high static pressure, making it excellent for exhausting heat from small enclosures.

• RPM Monitoring: Connect the 3-pin lead to your controller (like an ESP32 or Arduino with a level shifter) to set up a "cooling alarm." If the RPM drops below 5000, your system can trigger a safe shutdown.

• Vibration Dampening: Because this fan rotates at 6500 RPM, it can generate slight vibrations. Use rubber anti-vibration mounts or small silicone washers during installation to keep your enclosure perfectly silent.

• Dust Management: In high-speed 40mm fans, dust buildup can quickly unbalance the blades. We suggest blowing out the fan with compressed air once every three months to maintain its silent performance.

Package Includes

• 1 x ADDA 4cm 4020 12V Silent Fan (JPD0402012MA3A11)
