Yes The wrong wiring of the electrically controlled silicone oil fan will burn out, because there is a protection design inside, and the positive and negative power lines are connected backwards, resulting in short circuit. At this time, the current of the cooling fan will be much higher than normal, and the temperature rise of the motor itself will be high if the motor current is large. When the temperature reaches a certain level, the driving IC will be damaged due to overheating, and the cooling fan will be broken.
