1. Check if the fan is normal or if there is foreign matter entering the fan, which hinders the fan from turning.2. Pull out the fan plug and connect the 12V power supply for testing. Pay attention to the positive and negative poles, and the red line is the positive pole.If the test is still unresponsive then a new fan needs to be replaced.
