A compact USB-powered cooling fan for FPV pilots and drone builders. It suits cooling video transmitters, flight controllers, ESCs and other electronics while you configure, flash firmware or bench test. Running straight from a USB port, it keeps components from overheating when the aircraft is stationary and the props are moving no air.
The 40mm fan runs a brushless motor for dependable operation on little power. Mounting holes at each corner make it easy to fix to a workbench, charging station or a custom 3D-printed stand.
