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.

"Why?" leads to "what about it".

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

That's enough to call it defective and ask for your money
back. Although electrical parts returns often meet with some
resistance.

Heh.
