FAN 305MM 20V - Ingco

I have purchased my third Ingco fan in the last year, and each time the motor has failed. The most recent fan I bought was on March 12, 2025, and after just one week, the motor started making a loud, unpleasant noise. It only stops making this noise when the motor heats up. The model is FAN 305MM 20V INGCO. I emailed Ingco about getting a new motor, but I have not yet received a response.
