I would have thought idling for 15 minutes would cause a temperature increase if there is no flow through the radiator until the fan cuts in?
Is the problem the fan does not control the temperature after it cuts in initially...it should switch on and off as required to control the temperature.
If the fan can't bring the temperature down, the rad could be partially blocked internally, among other things.
