DC Fans

DC fans are a type of small motors designed to cool electronic components, from CPUs and GPUs to hard drives, power amplifiers, and analog-to-digital converters (ADCs). They are commonly made of plastic and have a long service life span that can exceed 20 years. Depending on their size, most of the DC fans operate at speeds from 500 to 4000 RPM, with air flow rates from 0 to 3 cubic feet per minute. To keep the temperature within an optimal range, most of these fans feature adjustable rotation speed and multi-stage speed settings.

FAD1-08025CAJW11 Application Field and Working Principle

The FAD1-08025CAJW11 is a medium-sized DC fan designed for cooling high-end components such as processors, power amplifiers, and ADCs. It operates at speeds between 600 and 5000 RPM, with an airflow rate of up to 2.5 cubic feet per minute. It includes 2-stage speed settings and adjustable rotation speed for a better thermal performance. This fan features a low-noise operation of up to 25 dBa making it suitable for quiet work environments.

The FAD1-08025CAJW11 runs on 12/24V DC sources and has a low power consumption of up to 1.02W. It can be built into electronic devices such as CPUs, GPUs, motherboards, switch boxes, and power converters. Thanks to its ball bearing design, this fan has a long service life of up to 20,000 hours.

This DC fan contains a permanent magnet motor, two capacitors, an actuating rotor, and a spinning impeller. This combination implements the Whittle\'s law of motor, which states that the block in which the stator and the rotor defines the total power output from the motor. This law determines the RPM of the fan depending on the voltage source connected to the motor. The power obtained from the motor is transformed into the kinetic energy necessary to create airflow.

Moreover, the blades installed on the motor increase the net power of the fan when they are spinning in air. The faster the fan moves in air, the more power output increases, resulting in more air flow. This fan is also capable of operating in environments with temperatures ranging from -20 to +70˚C.
