Condenser Permanently with charge resistance???

Hi, I want to build a fan recirculation control for the fans of the power stage. In addition, my question: Can I leave the resistor to charge the capacitor in the line, or does someone like me build a charging electronics for the capacitor??? How much best for 6-10 fans, everyone probably needs about 2-3 watts. should so 1-2 minutes recirculation. Hope someone can help me.
