Delock Radial Fan 12V DC 40x40x20mm with 3-Pin Connector

The Delock radial fan is a high-performance cooling solution engineered for effective thermal management in compact electronic environments. Measuring 40x40x20 mm, this blower-style fan is specifically designed to deliver concentrated airflow, ensuring that heat is efficiently dissipated from critical components. Operating on a 12V DC power supply, it integrates seamlessly into various computer systems and custom hardware setups using a standard 3-pin connector.

Advantages

The primary benefit of this radial fan lies in its blower design, which directs air precisely toward specific heat sources rather than dispersing it broadly. This focused cooling capability makes it significantly more effective than standard axial fans when dealing with restricted spaces or dense component layouts. Its compact dimensions allow for installation in tight enclosures where space is at a premium, while the 3-pin connector ensures compatibility with most standard motherboard fan headers for reliable power delivery and monitoring.

Suitable for

• Cooling specific electronic components on circuit boards
• Thermal management for compact computer enclosures
• Improving airflow over heat sinks in confined spaces
• Custom hardware projects requiring directed cooling

When it may not be suitable

This fan may not be suitable for applications requiring high-volume air circulation across large areas, as its blower design is optimized for focused, high-pressure airflow rather than general case ventilation. Additionally, it is not intended for use in environments exceeding its 12V DC power rating or in systems that require specialized pulse-width modulation (PWM) control, as the 3-pin interface lacks the fourth pin required for PWM speed regulation.

Key specifications

• Dimensions: 40 x 40 x 20 mm
• Operating voltage: 12V DC
• Connector type: 3-pin
• Design: Radial blower

How to use

To install the Delock radial fan, identify the mounting points on your heat sink or enclosure and secure the unit using appropriate screws. Ensure that the air intake is not obstructed by cables or other components to maintain optimal performance. Connect the 3-pin plug to an available fan header on your motherboard or a dedicated fan controller. Once connected, verify that the fan spins freely and that the airflow is directed toward the intended heat source.

What to consider before purchase

• Verify that your system provides a 12V DC power source
• Ensure there is sufficient clearance for the 40x40x20 mm dimensions
• Check that your motherboard or controller has a compatible 3-pin fan header
• Confirm that the blower-style airflow direction meets your cooling requirements

Usage recommendations

For optimal longevity and performance, ensure the fan is kept free of dust accumulation by cleaning it periodically with compressed air. Avoid operating the fan in environments with excessive moisture or extreme temperatures that fall outside standard operating conditions.
