Computer case fan DELOCK 67299 — 40 x 40 x 20 mm, 24 V DC, ball bearing, 0.19 m³/h, black

DELOCK 67299 is a compact 40 x 40 x 20 mm axial computer case fan designed for 24 V DC operation. It provides steady low-volume ventilation with an airflow of 0.19 m³/h and uses a ball bearing for reliable rotation and extended service life. The black fan is intended for cooling small PC compartments, embedded systems, network devices and electronics enclosures where parallel airflow and continuous ventilation are required.

Advantages

The fan's small size makes it easy to install in tight spaces while the ball bearing increases durability and ensures consistent performance over time. Its 24 V DC rating is suitable for a range of industrial and embedded applications, and the modest airflow reduces noise and power consumption compared with larger fans.

Suitable for

• Cooling small PC cases and chassis
• Ventilation of embedded systems and single-board computers
• Cooling network equipment and switches
• Airflow in electronics enclosures and control cabinets

When it may not be suitable

This fan is not intended for high-performance cooling of CPUs or GPUs that require large volume airflow. It may be insufficient where high static pressure or large heat dissipation is needed. For systems demanding strong airflow or low acoustic noise at high capacity, a larger or specialized fan should be considered.

Key specifications

• Dimensions: 40 x 40 x 20 mm
• Operating voltage: 24 V DC
• Airflow: 0.19 m³/h
• Bearing type: ball bearing
• Colour: black

How to use

Mount the fan in the desired position within the case or enclosure, ensuring the airflow direction aligns with the intended ventilation path. Connect the fan to a compatible 24 V DC supply, observing correct polarity. Secure the fan with appropriate screws or mounting hardware and verify that cables are routed to avoid contact with the blades. After installation, power on the system and confirm steady rotation and unobstructed airflow.

What to consider before purchase

• Required operating voltage (24 V DC) compatibility with your system
• Physical space available for a 40 x 40 x 20 mm fan
• Whether 0.19 m³/h airflow meets your cooling needs
• Preference for bearing type and expected lifetime

Recommendations

Use this compact 24 V axial fan for low-volume, continuous ventilation in small enclosures; ensure proper airflow direction and secure mounting. If higher airflow or pressure is required, select a larger or higher-performance fan.
