Axial Fan BLOW 40x10 mm 12V sliding bearing — compact 40mm 12V computer cooling fan

Compact axial fan BLOW 40x10 mm 12V with a sliding (sleeve) bearing is designed for forced-air cooling in small electronic enclosures and computer applications. Its low-profile 40×10 mm form factor provides airflow where larger fans cannot fit, making it suitable for single-board computers, network routers, small expansion cards and other tight-space installations. The fan operates from a 12V supply and delivers continuous airflow to help dissipate heat from chips, regulators and other heat-generating components.

Advantages

The BLOW 40x10 mm fan combines a compact size with reliable continuous operation thanks to its sliding bearing design. Its slim profile allows installation in constrained spaces without significant modification to the chassis. Designed for straightforward integration, the fan connects to standard 12V systems and provides consistent forced airflow to reduce component temperatures. The construction balances space efficiency, adequate airflow for small devices, and cost-effective replacement or upgrade.

Suitable for

• Cooling single-board computers and compact development boards
• Ventilation inside routers, modems and network appliances
• Supplementary cooling for expansion cards and small PCI/miniPCI enclosures
• Air circulation in small power supplies, chargers and control units

Key specifications

• Fan type: axial, low-profile
• Dimensions: 40 × 10 mm
• Rated voltage: 12 V DC
• Bearing type: sliding (sleeve)
• Typical application: electronics and computer component cooling

How to use

Install the fan in a location that allows unobstructed airflow across the components to be cooled. Secure the fan using appropriate mounting holes or brackets compatible with 40×10 mm fans, ensuring correct orientation for intake or exhaust airflow as required by the system design. Connect the fan to a 12V DC supply, observing correct polarity and using suitable wiring or connectors to match the host device. Avoid exposing the fan to conductive dust, liquids or debris that could impede the sliding bearing.

Usage recommendations

For extended service life, position the fan to minimize direct exposure to dust and contaminants and consider periodic inspection. If quieter operation or longer bearing life is required, evaluate alternatives with sleeve-to-ball bearing upgrades or larger-diameter fans where space permits.
