Fan DELOCK 67293 4 cm (40×40×10 mm) 0.18 m³/h Ball bearing 12V Black

Small axial fan by DELOCK designed for cooling PC components and electronics. The compact 40×40×10 mm frame with a 4 cm impeller provides parallel airflow to ventilate computer cases, small enclosures, drives and individual components. The fan runs on 12 V DC and uses a ball bearing for extended service life.

Advantages

The fan's compact dimensions make it easy to install in tight spaces and small housings. Ball bearing construction improves durability and running stability compared with plain sleeve bearings. Its simple black design suits various systems and maintains unobtrusive airflow without additional features.

Suitable for

• Cooling computer cases and internal components
• Ventilation of small enclosures and electronic housings
• Cooling drives, power supplies and single components

When it may not be suitable

This fan provides low airflow (0.18 m³/h) and is intended for small-scale ventilation; it may not be adequate for cooling large systems or high-heat components. It also does not include integrated speed control or advanced noise-reduction features, so applications requiring adjustable RPM or ultra-low noise may need a different model.

Key specifications

• Frame size: 40 × 40 × 10 mm
• Impeller diameter: 40 mm
• Airflow: 0.18 m³/h
• Bearing type: ball bearing
• Operating voltage: 12 V DC
• Color: black

How to use

Mount the fan in the intended location inside the case or enclosure using appropriate screws or mounting clips for a 40×40×10 mm frame. Connect the fan to a 12 V DC supply or a compatible motherboard/header, observing correct polarity. Ensure the airflow direction matches the desired intake or exhaust configuration and provide unobstructed air paths for effective cooling.

What to consider before purchase

• Required airflow and whether 0.18 m³/h meets cooling needs
• Available mounting space for a 40×40×10 mm fan
• Power source compatibility with 12 V DC and connector type
• Noise and speed control requirements (no built-in speed control)

Recommendations

Use this DELOCK 4 cm axial fan for supplemental airflow in small enclosures or to replace an existing 40 mm fan; position it to create a direct airflow path over the components that require cooling and verify secure electrical connections before operation.
