Axial fan BLOW Blow 70x15 mm 12V sliding bearing for PC cooling

The BLOW axial fan 70 x 15 mm is a compact 12V DC cooling fan with a sliding (sleeve) bearing designed for PC cooling and ventilation of small electronic enclosures. Its small footprint makes it suitable for installations with limited space where forced airflow is required to remove heat from processors, power modules or densely packed components. The fan provides targeted airflow for chassis, CPU coolers in compact builds, or auxiliary cooling of controllers and drives.

Advantages

This 70 x 15 mm fan offers a compact design that fits narrow mounting spaces while delivering continuous airflow at 12V DC. The sliding bearing construction keeps manufacturing costs and weight low and enables quiet operation in many typical desktop and embedded applications. The fan's modest dimensions and straightforward electrical requirements make it easy to replace existing small fans or add supplemental ventilation to reduce component temperatures and improve system reliability.

Suitable for

• Cooling of small PC chassis and compact desktop builds
• Auxiliary cooling for CPU coolers in tight spaces
• Ventilation of small electronic enclosures and control boxes
• Cooling of power supplies, drives, and expansion cards in restricted areas

Key specifications

• Dimensions: 70 x 15 mm (axial fan)
• Operating voltage: 12 V DC
• Bearing type: sliding (sleeve) bearing
• Form factor: low-profile, compact fan for tight mounting spaces
• Intended use: chassis and component ventilation for PCs and small electronics

How to use

Mount the fan using the appropriate screws or brackets for 70 mm fans, ensuring proper orientation for intake or exhaust based on your cooling design. Connect the fan to a 12V DC source or compatible fan header on the motherboard or power supply, observing correct polarity. Verify airflow direction before final assembly and secure wiring to avoid contact with the blades. For best results, install the fan where it supplements the main airflow path—either directing cool air toward heat-generating components or exhausting warm air away from them.

Usage recommendations

Use this fan where space constraints prevent larger fans; plan periodic inspection for dust buildup and replace the fan if noise or reduced airflow indicates bearing wear. For applications requiring long-term continuous operation or the lowest noise levels, consider bearing type impact on longevity and evaluate alternatives if higher durability is needed.
