Auxiliary Cooling Fan (12 V)

This auxiliary cooling fan is intended for additional forced-air cooling when operating MOSFET switch boards under heavy load conditions. The fan plugs directly into the on-board 12 V fan connector on the MOSFET switch boards we sell and does not require any external power supply.

By providing active airflow across both the MOSFET devices and the PCB itself, the fan helps reduce component temperatures during sustained high-current or high-frequency operation. This improves thermal stability and supports long-term reliability of the system.

The compact 80 × 80 × 25 mm form factor allows effective airflow while remaining easy to integrate into enclosures or open test setups. The fan can also stand upright by itself, making it easy to position and direct airflow toward the MOSFETs and the board without requiring additional mounting hardware.

A dual ball bearing design ensures stable operation and long service life, making the fan suitable for continuous-duty applications. A 30 cm power cable provides sufficient reach for clean and flexible installation directly from the board’s fan header.

Typical applications:

• Active cooling of MOSFETs during sustained high-current operation
• Additional PCB cooling during high-frequency switching
• Thermal management in enclosed or low-airflow setups
• Laboratory and experimental setups operating for extended periods
