DELOCK computer case fan 4 cm (40 x 40 x 10 mm), ball bearing, 0.18 m³/h, 5 V DC, black

DELOCK 67286 is a compact 4 cm (40 x 40 x 10 mm) computer case axial fan designed for 5 V DC operation. With a ball bearing and an airflow of 0.18 m³/h, this black fan provides targeted cooling for small enclosures, single-board computers, expansion cards and other tight spaces where a low-profile ventilation solution is required.

Advantages

The fan’s small size and low-profile design allow installation in confined spaces while the ball bearing construction contributes to a longer service life and stable operation. Rated for 5 V DC and offering a steady airflow of 0.18 m³/h, it provides efficient air circulation for localized cooling without requiring high drive voltages.

Suitable for

• Cooling single-board computers (e.g., Raspberry Pi) and mini PCs
• Ventilation of small computer enclosures and expansion card slots
• Use in compact electronics, routers, and set-top boxes

When it may not be suitable

This fan is not intended for cooling large PC cases or systems that require high airflow. Its airflow rating of 0.18 m³/h and small dimensions limit its effectiveness in applications that demand strong or broad-area ventilation. For environments requiring ultra-quiet operation, additional acoustic data should be checked as small fans can be relatively louder at higher speeds.

Key specifications

• Size: 40 x 40 x 10 mm
• Type: axial case fan
• Bearing: ball bearing
• Airflow: 0.18 m³/h
• Rated voltage: 5 V DC
• Color: black
• Quantity: 1 piece

How to use

Install the fan in the desired position inside the enclosure or on the device so that the airflow direction aligns with the intended cooling path. Secure the fan with appropriate screws or mounting hardware and connect it to a 5 V DC power source compatible with your system. Ensure adequate clearance around the fan for unobstructed airflow and avoid contact with cables or components that may interfere with the blades.

What to consider before purchase

• Confirm that a 40 x 40 x 10 mm fan fits the intended mounting location.
• Verify that your system provides a 5 V DC power source or appropriate connector.
• Ensure the airflow (0.18 m³/h) meets cooling requirements for your application.

Recommendations

Use this Delock 4 cm fan for targeted, low-profile cooling tasks such as single-board computers, small enclosures and expansion cards. Combine with proper airflow routing and intake/exhaust openings for optimal temperature control.
