Solution
1. Change a driver board
2. Check if the fan motor speed
is too low or fan motor
damaged, change another one
3. Change another fan blade
1. Change a driver board
2. Check if the motor speed is
too low or fan motor damaged,
change another one
3. Change another fan blade
4. Check the input voltage
1. Detect DC motor, replace
with a new one
2. Change a new main board
3. Find out the barrier and work
it out
1. Change a new driver board
2. Check if the fan motor speed
is too low or fan
damaged, change another one
1. Change a new driver board
2. Check if the motor speed is
too low or fan motor damaged,
change another one
3. Change another fan blade
4. Check if the screw is loose
Check whether the voltage is
stable
