The largest fan in the 5V USB range, this 90mm cooling fan provides maximum airflow for electronics projects. Simply plug into any USB port for immediate cooling — no drivers or setup required.

The USB connector can be cut off to wire the fan directly to a 5V power source. While there's no built-in PWM or feedback pin, you can control fan speed using a motor controller, H-Bridge, or MOSFET. As an inductive load, a flyback diode is recommended to protect your circuitry.
