I bought 2 5v 120mm USB coolers for TVbox one of them rotates normally the other cooler when connected to the USB port it tries to rotate for 1 second and turns off and for this cooler is it possible to repair? fan SXDOOL Model: 12025L05R DC 5V 0.2A 1200RPM DC BRUSHLESS FAN
First figure out whether it's the fan or the USB port, or one fan is
just on the wrong side of what a basic (non-charging) USB port
can deliver before hitting a self protection limit.
I have another cooler of the same model 120mm usb bought from the same seller and on the same USB port and it works normally but the one I mentioned tries to spin and I also tested it on the smartphone charger and the same problem
