Primary fan is the passenger side fan and will do most of the work. The secondary fan (driver side) is rarely in use, or used. As long as the primary fan comes on when the temp reaches around 235 degrees (or close to the red). Then you are fine.

relax. these things act like they are getting super hot, when in reality, they are fine. My primary doesnt come on until the needle in the instrument cluster touches the red. When it does kick on, the thing cools off super fast.
