Default At what vehicle speed do push/pull fans not help?
In a TT setup with push in front of the intercooler and a pull behind the radiator, is there a vehicular speed at which the fans no longer help passing airflow?

good question, i heard from a friend after about 30mph the fans don't really have an effect. it would be good to know for sure though.

Wouldn't it be along the lines of vehicle speed in feet per min x cubic feet of the radiator?

Thinking about dropping $200 for a complete fan set up to replace the weakening stock set up...I want to chill a Jack n Coke while driving.
