So you don't have the motor driven fan? Just the electric? If your radiator works sufficiently you may never need the electric. Who knows. Time will tell.
Not to be disrespectful but how hot did you expect the 230 to get? Now the electric fan is just blocking your radiator
You better wait til summer before making any rash changes.
