I don't think the fan is the real source of your problem. I suspect you may need to replace the radiator, which may be restricted due to corrosion or mineral buildup. Most Civic radiators need replacing between 130,000 to 150,000 miles.

Electric fans are mainly for keeping the engine cool when you're idling in traffic or moving slowly.
