1999 Cadillac DeVille Question: what causes the motor to overheat

on the freeway cruising 62mph, the car runs fine, however when I slow down the all hell breaks loose and the car overheats. In the the city, the car overheats after 30 minutes driving. -
Answer 1
Best guess : radiator cooling fans are not working. Ram air at speed will cool rad. but at slower speed fans have to do it. -
Answer 2
most likely the cooling fans or its circuit...this vehicle has a complicated cooling fan electric circuit. -
