The fan issue can be a symptom of so many different problems. From what you’ve said, it could be a thermostat problem, or even just an air lock.
It could also be a sensor problem, this is far from unknown in the RCZ.

Yes more likely a temp sensor or thermostat which both are encased in the housing.
