| I run the 18" MK8 fan with no issues. the single speed fan is rated ~3500 and 2 speed is rated ~4300 on high. I run the 2 speed fan, but only the high windings. PWM controller with a soft start is definitely recommended as they draw 90-100 amps on startup with a relay fan. It was drawing 10-12 amps with the PWM controller. Stock alternator has been fine for me.
