Fan DELOCK 67287 axial 4 cm, 5 V DC, ball bearing, 0.19 m³/h, black

DELOCK 67287 is a compact 40 × 40 × 20 mm axial housing fan designed for 5 V DC operation. The black fan uses a ball bearing and delivers an airflow of 0.19 m³/h, making it suitable for ventilating small enclosures, embedded systems, routers and other electronic components in confined spaces.

Advantages

The fan’s ball bearing construction provides extended service life and reliable performance under continuous operation. Its small form factor and 5 V DC compatibility allow easy integration into compact electronic projects and tight installation spaces while maintaining steady airflow.

Suitable for

• Cooling components in small computer cases and micro-PCs
• Ventilation of embedded systems and industrial controllers
• Cooling routers, switches and network devices
• Use in compact enclosures, 3D printers or DIY electronics projects

When it may not be suitable

This fan provides relatively low airflow (0.19 m³/h) and is intended for small or confined spaces; it may not be adequate for cooling large PC cases, high-performance GPUs, CPUs or systems that require high-volume airflow. Also, it is designed for 5 V DC supply and is not compatible with higher-voltage fan headers without appropriate adapters or controllers.

Key specifications

• Type: Axial housing fan
• Dimensions: 40 × 40 × 20 mm
• Operating voltage: 5 V DC
• Bearing: Ball bearing
• Airflow: 0.19 m³/h
• Colour: Black

How to use

Install the fan in the desired position inside the enclosure or device with appropriate screws or mounting hardware. Connect the fan to a 5 V DC power source, ensuring correct polarity. Verify that the airflow direction aligns with the intended cooling path and that the fan intake and exhaust are not obstructed. Regularly check for dust buildup and clean as needed to maintain performance.

What to consider before purchase

• Required operating voltage (5 V DC) and compatibility with your device’s power source
• Physical dimensions and available mounting space (40 × 40 × 20 mm)
• Airflow needs — 0.19 m³/h may be insufficient for high-demand cooling
• Noise and bearing type — ball bearing offers durability but check acoustic requirements

Recommendations

For best results use this Delock axial fan in small enclosures or devices with limited space, position it to promote parallel airflow across heat-producing components, and maintain periodic cleaning to prevent dust accumulation and ensure continuous cooling performance.
