Electric fans offer superior flow, mounting flexibility, and computer control compared to mechanical fans. Years ago, it used to be that mechanical fans offered the best performance, but today that isn’t so. Mechanical fans are subject to problems with vibration due to air turbulence when run at high RPM. This can lead to premature wear on the water pump. Mechanical fans can also consume up to 20 or more horsepower. Viscous thermo-clutches used to control mechanical fans can be inconsistent and unreliable and offer no computer control. Mechanical fans are limited in the airflow they can provide at idle and slow speeds because they are turning at low RPM. Because the mechanical fan attaches to the engine and not the radiator, clearance must be maintained so that any chassis or engine-mounting flex doesn’t cause the fan to eat the radiator (which is bad for cooling!). This makes shrouding a mechanical fan a more difficult and cumbersome affair that consumes valuable under-hood space.

By contrast, electric fans can be very neatly packaged and integrated with the radiator and shroud.

Because they aren’t coupled to engine speed, electric fans can produce full airflow all the way down to idle.

Quality fans like those from SPAL are rugged and reliable with sealed waterproof motors and tough plastic housings.

Because they are electrically powered, electric fans can be computer controlled by the engine`s ECM or thermostatically controlled via a thermistor (a temperature sensitive switch installed in the coolant flow).

Electric fans are available in a large variety of styles and sizes to fit any size or shape radiator. I like to run two smaller fans in an offroad rig simply for redundancy`s sake – that way, if one quits, you still have one operational. You don’t get this choice with a mechanical fan.

“Puller” style electric fans that mount behind the radiator and pull air through the radiator, as shown here, are the best choice because they are both more efficient (move more air for given fan RPM) than pusher fans, and they obviously don’t block airflow from the front of the rad like a “pusher” style fan does.

A fan’s capability is measured in CFM, as we have noted. However, the consumer needs to be careful when shopping for a fan by rated specs. Any given measurement for a fan’s CFM must be taken (and therefore should be quoted) at a given air pressure (hey – that sounds familiar – pressure and flow being related!  Man – physics rocks!). Too often this information is not quoted, and you can bet that the CFM spec is therefore rated at 0PSI which is not representative of actual operating conditions. Just as important, a fan’s flow spec should also include the voltage provided and amount of current drawn for each pressure/CFM rating. This is a good sober second-check of a fan’s claimed capabilities. Be extremely wary of a fan that claims it pulls 3000CFM while drawing only 10amps – it’s just not realistic.
