Perhaps when the clutch isnt engaged the fan spins freely and when it does it spins faster !!!!
the way a clutch fan works, is that when theres no air flow coming through the rad(at a stop revving the engine) the fan will always spin, however, at speed the force on the fan causes the clutch to relase and slip, making the fan not spine and instead uses the rushing air through the radiator to keep it cool.....
