5V Square USB Fan - 4 cm

Discover our USB-powered 5V cooling fans! These fans offer easy plug-and-play cooling, delivering instant airflow to prevent overheating. They're ideal for small computers, FPGAs, motor drivers, and other heat-sensitive electronics. Key features include: Plug-and-play USB power for quick cooling; a direct 5V wiring option by simply cutting off the USB connector; basic PWM control where you can regulate speed using a motor controller, H-Bridge, or MOSFET; and protection for your circuitry with a flyback diode (we recommend the MOSFET Driver Stemma for easy integration). We have multiple sizes of 5V USB-powered cooling fans to fit your project needs. Each fan comes with front and back protective grills, mounting screws, and nuts for a secure installation.

Using this 5V USB fan is a breeze. You can simply plug it into any USB port for quick cooling. If you prefer, you can cut off the USB connector and power it directly with 5V. To control the fan speed, you can use a motor controller, H - Bridge, or MOSFET. Since fans are inductive loads, make sure to use a flyback diode to avoid voltage spikes. We suggest using the MOSFET Driver Stemma for easy setup. When installing the fan, use the included front and back protective grills, mounting screws, and nuts for a secure fit. As for maintenance, keep the fan clean by gently removing any dust with a soft brush or compressed air. Avoid using harsh chemicals or getting the fan wet. This will help keep the fan running smoothly and extend its lifespan.
