Cooling fan on max speed when car is started

The weather is changing here. The low this morning was 41 degrees.
This should not matter becausein Feb of this year I was driving the car in Germany when it was -15.

The fan will turn on as soon as I start the motor and it will remain on while driving. This just started this morning but I aleardy called my SA.

What could be the issue?
Thermostat (no way, motor was cold)
Relay?
some electical component?
