The 12V 12025 Cooling Fan is a high-airflow DC cooling fan designed for electronic equipment, enclosures, power supplies, control cabinets, computers, 3D printers, industrial electronics, and DIY cooling applications.
With a standard 120 × 120 × 25mm frame, 2500RPM operating speed, and airflow of approximately 83.2CFM, the fan provides effective forced-air cooling for equipment that generates significant heat.
The dual ball bearing design provides reliable operation and makes the fan suitable for applications requiring extended operating periods.

High Airflow Cooling
The fan delivers an airflow of approximately:
83.2CFM
This provides strong air circulation for removing heat from electronic equipment and improving ventilation inside enclosures.
It can be used either to bring cooler air into an enclosure or exhaust warm air from the system.
2500RPM Fan Speed
The fan operates at approximately:
2500RPM
The combination of high rotational speed and a 120mm fan frame provides effective airflow while maintaining a specified noise level below 36dBA.
Dual Ball Bearing
The dual ball bearing construction is designed for reliable and durable operation.
Compared with basic sleeve-bearing fans, ball-bearing designs are generally better suited to applications involving longer operating periods and elevated temperatures.
12V DC Operation
The fan operates from a 12V DC power source.
-
Rated Voltage: 12V DC
-
Rated Current: 0.3A
-
Calculated Power Consumption: Approx. 3.6W
A suitable regulated 12V DC power supply capable of providing at least the required current should be used.
2-Pin Connector
The fan is fitted with a 2-pin XH2.54 connector for simple power connection.
The two-wire configuration provides the power connections required for basic fan operation.
This is a standard fixed-speed DC fan configuration and does not provide a dedicated PWM speed-control or tachometer signal unless otherwise specified.

Installation
For effective cooling, install the fan so that airflow passes across the components that generate the most heat.
Typical configurations include:
-
Air Intake: Pulling cool air into an enclosure
-
Air Exhaust: Removing hot air from an enclosure
-
Component Cooling: Directing airflow toward heatsinks, power supplies, motor drivers, or other heat-generating components
For best enclosure cooling, an intake and exhaust airflow path should be provided.
Power Connection
Connect the fan to a suitable 12V DC power source.
Because the fan can draw approximately 0.3A, do not power it directly from a microcontroller GPIO pin.
For Arduino, ESP32, Raspberry Pi, or other microcontroller-controlled applications, use a suitable MOSFET, transistor, relay, or fan driver circuit between the controller and the fan.
Package Includes
Important Note
Before connecting power, verify the positive and negative wire polarity of the specific fan supplied.
The fan requires approximately 12V DC at 0.3A. Use a power supply with sufficient current capacity.
Mounting screws, fan guards, filters, power supply, and control electronics are not included.
