An electric fan completely removes the mechanical load of spinning the fan from the engine. It places an additional draw on the electrical system, but this is a more efficient means of spinning a fan, and it has a smaller impact on engine drag.Feb 27, 2010
Do electric fans add horsepower?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.Apr 1, 2018
What are two advantages of electric cooling fans?
A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.Oct 19, 2014

What is the highest CFM electric radiator fan?
Super Duty Motor - Be Cool has the answer when you need the maximum airflow possible from a single 16” electric fan. The Super Duty motor produces 3,140 cubic feet of airflow per minute (cfm) when mounted against a radiator core. This is the highest-rated CFM available from a through-the-radiator-core 16” electric fan.
Although they will place an additional draw on the electrical system, they are a more efficient alternative to mechanical fans and don't cause the dreaded parasitic horsepower loss. Here are a few other advantages of electric fans: Consistent cooling—they maintain their airflow at all times. Reduced water pump wear.Jul 24, 2012
How much horsepower does a flex fan take?
I'm sure a flex fan takes 5-10 horse but some large electric fans can pull 30 amps. Might be a horse or two just to make that. For the money you can't go wrong with a standard thermal coupled mechanical fan and a proper shroud.May 17, 2009
When compared to an electric fan, fan clutches are quite inefficient. ... The benefits of a Thermatic Fan lay in its ability to provide constant air flow, improved fuel economy, better air-conditioning performance, cooler engine running and increased engine power.Mar 4, 2017
