Axial fan BLOW 120x25 mm 24V ball bearing for electronics cooling

Axial fan BLOW 120x25 mm 24V ball bearing for electronics cooling is a compact cooling solution designed for electronic devices, enclosures and ventilation systems that require a 120 mm diameter and 25 mm thickness fan operating at 24 volts. The fan uses ball bearings for increased durability and stable rotational performance, delivering a steady airflow to remove heat from components and maintain reliable operating temperatures in industrial and hobby applications.

Advantages

The ball-bearing construction offers extended service life and consistent rotational stability compared to sleeve-bearing designs, enabling continuous operation under varied orientations and temperatures. The 24V rating provides compatibility with common industrial and vehicle power supplies while reducing current draw compared with lower-voltage alternatives. Its 120×25 mm form factor fits standard mounting patterns and tight-depth assemblies, and the compact design balances airflow and noise for effective local cooling of electronics.

Suitable for

• Cooling PC cases, power supplies and single-board computers in custom builds
• Ventilation of control cabinets, enclosures and industrial equipment
• Cooling of LED drivers, amplifiers and other heat-generating modules
• Use in vehicles, solar inverters or battery systems with 24V supplies

Key specifications

• Fan type: axial
• Dimensions: 120 mm diameter × 25 mm thickness
• Operating voltage: 24 V DC
• Bearing type: ball bearing
• Mounting: standard 120 mm mounting pattern for 25 mm depth applications
• Typical applications: electronics cooling, enclosure ventilation

How to use

Install the fan in the enclosure or device so that the airflow direction aligns with the intended cooling path; check the arrow marking on the housing for rotation and airflow direction. Secure the fan using screws or vibration-damping mounts compatible with the 120 mm mounting pattern and ensure adequate clearance for intake and exhaust. Connect the fan to a stable 24 V DC supply, observing correct polarity and using appropriate wiring and fusing for the application. Where speed control is required, use a compatible 24 V PWM controller or voltage regulator designed for ball-bearing fans.

Usage recommendations

For reliable long-term operation, keep intake and exhaust openings free of dust and debris, and provide periodic inspection in dusty or high-vibration environments. When installing in enclosures, combine the fan with appropriate air filters and consider placing the fan to create a directed airflow path across the hottest components. Avoid prolonged operation beyond the specified voltage and mounting outside recommended orientations if not supported by the system design.
