## Description

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. Key Features Plug-and-Play USB Power – Connect to any USB port for instant cooling Direct 5V Wiring Option – Cut the USB connector to wire directly to a 5V source Largest in the Range – 90mm fan delivers the most airflow of all sizes Standard 25mm Depth – Common form factor compatible with most fan mounts Protective Grills – Front and back grills included for safety Secure Mounting – Includes screws and nuts for easy installation Specifications Voltage – 5V DC Current Draw – 0.2A Fan Dimensions – 90 × 90 × 25mm Mounting Holes – 82 × 82mm spacing, 4.5mm diameter Cable Length – Approximately 1 metre (USB-A connector) Also Available 5V Square USB Fan – 3 cm 5V Square USB Fan – 4 cm 5V Square USB Fan – 5 cm 5V Square USB Fan – 6 cm 5V Square USB Fan – 7 cm 5V Square USB Fan – 8 cm Ideal For Cooling single-board computers and development boards FPGA and motor driver thermal management 3D printer electronics cooling Enclosure ventilation for electronics projects Package Contents 1× 5V USB Fan (90mm) 2× Protective grills (front and back) 4× Mounting screws and nuts Tip: Fans are inductive loads — use a flyback diode when switching with a MOSFET or H-Bridge to protect your circuitry.
