Radiator fan runs at high speed on cold

Hello all. lately, when I start my x5 in the morning (from cold) I notice that the fan runs at a very high speed and is very loud. it stays like this for a while. This is with AC turned off. any idea what it could be? my understanding is the fan should only kick in when coolant temp is high (thermostat in open position) or if AC is switched on.

Thanks in advance.
