340 coolant temperature
I built a similar setup for my big block. running duel 14" fans. the fans are sealed to the radiator and i have holes for air to pass thru during high speed cruising. when my fan controller was working the first fan would come on at 175 and 2nd fan come on at 185. it would cool the engine down to 170 instantly and cycle off. my set up worked very well in bumper to bumper traffic for over an hour in 80* temps.
