Re: Colling fan delima
As a general rule, a mechanical fan in good shape will move a lot more air than an aftermarket electric fan. OEM electric is going to be comparable.
Also, tech tip:
At freeway speeds, the air blasting through your grill is moving faster than the fan will move it anyway. If you overheat at freeway speed, you don't have an airflow problem (unless the radiator is blocked) you have a water flow issue.
Around town, you need the airflow help from the fan.
