Delock Radial Fan 12V DC 40x40x10mm with 3-Pin Connector

The Delock radial fan is a compact 12V DC blower engineered for effective thermal management in electronic devices and computer systems. With its centrifugal design, this fan is specifically built to provide focused airflow, making it an excellent solution for cooling components in tight spaces where traditional axial fans might struggle to maintain adequate air circulation. Measuring 40x40x10 mm, it offers a space-saving footprint while ensuring reliable operation through its standard 3-pin connector.

Advantages

The primary benefit of this radial fan lies in its centrifugal airflow mechanism, which directs air at a 90-degree angle, allowing for precise cooling of specific hotspots on circuit boards or within compact enclosures. Its robust 12V DC motor ensures consistent performance, while the compact dimensions allow for integration into small-form-factor builds, industrial controllers, or custom electronics projects. The 3-pin connector provides a secure power interface, facilitating easy installation and compatibility with various motherboard headers or power distribution boards.

Suitable for

• Cooling small-form-factor computer cases
• Thermal management for 3D printer hotends
• Active cooling for electronic control units
• Air circulation in compact industrial enclosures
• Replacement fan for specialized hardware

When it may not be suitable

This radial fan is not intended for high-volume case ventilation where a large axial fan would be more efficient at moving air through an entire chassis. It is also not suitable for applications requiring silent operation in noise-sensitive environments, as the centrifugal design may produce a distinct sound profile compared to standard fans.

Key specifications

• Dimensions: 40 x 40 x 10 mm
• Operating voltage: 12V DC
• Connector type: 3-pin
• Design: Radial (centrifugal) blower
• Color: Black

How to use

To install the fan, ensure the mounting surface is clean and free of obstructions. Align the fan outlet with the component or area requiring cooling. Secure the unit using appropriate screws or adhesive pads, ensuring the intake port remains unobstructed to allow for proper airflow. Connect the 3-pin plug to a compatible 12V power header on your motherboard or power supply unit. Verify that the fan spins freely upon power-up and that the airflow is directed toward the intended heat source.

What to consider before purchase

• Verify the voltage requirements of your power source match the 12V DC specification.
• Check the available space in your enclosure to ensure the 40x40x10 mm dimensions fit correctly.
• Confirm that your motherboard or controller supports a 3-pin fan connection.
• Assess the airflow direction to ensure it meets your specific cooling needs.

Usage recommendations

For optimal longevity and performance, ensure the fan intake is kept free of dust and debris. Regularly inspect the fan for any signs of obstruction or mechanical wear, especially in environments with high particulate matter.
