pretty sure what you are seeing is normal, the pcm takes the engine cooling temp and if it sees it needs more fan then it will engage the fan , the duty cycle of the fan is determined from different inputs , load , ect, etc. how much the fan is engaged is determined by those readings , i guess what im getting at is there is no set schedule for the fan , if the pcm thinks it needs it then it will be engaged
