Axial Fan BLOW Blow 120×25 mm 24V sleeve-bearing for PC cooling

The BLOW 120×25 mm 24V sleeve-bearing axial fan is designed for general-purpose PC and electronics cooling. With a 120 mm diameter and 25 mm thickness, this fan provides targeted airflow for chassis ventilation, CPU coolers with compatible mounts, and electronic enclosures. The fan operates from a 24V DC supply and uses a sleeve-bearing (sliding bearing) construction appropriate for applications where moderate noise levels and standard lifetime expectations are acceptable.

Advantages

The axial design delivers directed airflow suitable for cooling stacked components and ventilation ducts. The 24V DC operation allows integration into systems using a higher-voltage supply common in some industrial and server environments. Sleeve-bearing construction offers a cost-effective solution for continuous operation in non-critical noise-sensitive installations and where heavy-duty anti-vibration features are not required.

Suitable for

• PC chassis ventilation and case fan replacement
• Cooling small server racks and network equipment with 24V supply
• Ventilation of electronic control cabinets and industrial enclosures
• Integration into third-party CPU or chipset cooling assemblies with compatible mounting

Key specifications

• Frame diameter: 120 mm
• Frame thickness: 25 mm
• Rated voltage: 24 V DC
• Bearing type: sleeve (sliding) bearing
• Fan type: axial fan
• Typical application: chassis and enclosure cooling

How to use

Install the fan in the intended airflow orientation, ensuring correct intake and exhaust directions for optimal chassis or enclosure ventilation. Secure the fan using the appropriate mounting points or brackets for a 120×25 mm fan, and connect the power leads to a regulated 24V DC supply with correct polarity. Avoid obstructing the impeller and maintain a clearance that prevents cable contact with the blades. For best performance, route cabling to minimise airflow disruption and verify that the power source can supply the operating current.

Usage recommendations

For longer service life and lower noise, consider installing the fan in locations with moderate ambient temperature and minimal dust exposure. Periodic cleaning of vents and impeller surfaces will help maintain airflow. In noise-sensitive or continuous high-demand applications, consider fans with ball bearings or higher-rated lifetimes and plan for periodic replacement according to operating hours.
