After the circuit is added with a thermistor switch MAX6501, if the system temperature is higher than the regulated value, then it will warn to replace the fan fault detector. RT thermistor should be close to MAX6501 when it is connected in, and it is located in the fan wind, so the fault of stopping running can be detected quickly, the reason is that when the fan is not running, there won't be air to pass RT and MAX6501. The circuit is not fitted in the fan with the closed lock rotator detector. If a fan is fixed with a rotator, the fan will restart in 0.5-1S after it stops.
