How much horsepower do you gain with electric fan?
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.
Where did the electric fan come from?
The first electric fan was made in 1886 by Schuyler Wheeler. Early fans were all DC powered. After the 1890s fans with AC motors were produced. In the late 1920s GE released a design which had overlapping blades, which made fans much more quiet.
Are electric fans worth it?
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.
What size is a box fan?

Higher pressure air has higher density. When you push, the air in the duct will have higher pressure than if you were pulling form the other end. This means that for a given unit of time, more air flows though a pushed duct than a pulled one (again- assuming all other things equal).
Are Flex fans better than clutch fans?
