## Summary description

Axial cooling fan BLOW Blow 40×20 mm, 12V DC with ball-bearing design. Compact 40×20 mm size suitable for small enclosures, electronics cooling, or PC auxiliary airflow. Provides continuous DC-powered ventilation with durable ball bearings for longer life and stable operation. Ideal for spot cooling in routers, small cases, power supplies, and embedded systems.

## Long description

Axial fan BLOW Blow 40×20 mm 12V ball-bearing is a compact DC cooling fan designed for spot ventilation in small enclosures and electronic assemblies. With a 40×20 mm frame and 12V operating voltage, this fan provides continuous airflow for cooling components in routers, small PC cases, power supplies and embedded systems. The ball-bearing construction improves durability and stability under continuous operation, making it suited for applications where small size and reliable airflow are required.
Advantages
The ball-bearing design reduces wear and supports longer operational life compared with simpler bearing types, while maintaining stable rotational speed at 12V DC. Its compact 40×20 mm form factor allows installation in confined spaces and on tight mounting points. The fan delivers continuous, low-profile ventilation suitable for targeted cooling without significant bulk, and its standard axial design provides a direct airflow path for efficient heat removal from localized hotspots.
Suitable for
Cooling small PC cases and auxiliary airflow for desktops
Ventilation of routers, network switches and telecom enclosures
Spot cooling for power supplies and DC-DC converters
Embedded systems, industrial controllers and single-board computers
Small electronics enclosures, fans for ventilation and airflow management
Key specifications
Frame size: 40 × 20 mm
Type: axial DC fan
Nominal voltage: 12 V DC
Bearing type: ball-bearing for extended durability
Mounting: compact footprint for confined spaces
How to use
Install the fan in the enclosure or device with correct orientation to direct airflow toward the component to be cooled. Secure the fan using appropriate mounting screws or clips compatible with a 40×20 mm frame. Connect the power leads to a stable 12V DC source, observing polarity to prevent damage. Ensure adequate clearance for airflow and avoid obstructions near the intake and exhaust. For optimal performance, verify that the fan runs freely before continuous operation and that any dust filters or vents are clean.
Usage recommendations
For improved longevity, mount the fan in a location with limited vibration and adequate ventilation. Regularly inspect and clean the fan blades and surrounding vents to maintain airflow. When integrating into systems with variable loads, consider monitoring temperature and using the fan with a basic speed-control or PWM solution at a compatible voltage to balance noise, airflow and component life.
