That's the key question, right? Here's our advice: If you are looking for a performance upgrade then the electric fan is for you. Make sure the electric fan covers 70 percent of the radiator core and moves enough airflow for the engine size (a rule of thumb is at least 2,800 cfm for a 5.0L engine). The electric fan would be a cooling solution for vehicles that typically drive at low vehicle speeds with low engine rpm, such as cruising. If you have a 4-core radiator or towing heavy loads then we recommend you stick with a belt driven fan.

Electric fans now outperform mechanical fans in nearly every application, except towing and dirt oval track racing.

Flex fans are a poor design for performance applications. They move less air at higher RPM, and only consume a fraction less power than standard fixed pitch fans.

Clutch-style fans are inconsistent and we do not recommend their use for any application, if possible.
