Need Help figuring this out. I changed the thermostat and the water pump for my 2006 Bmw 325i around 3 months ago and I drove it back then for like an hour with no issues and then parked it.  
Now 3 Months later, I try to drive it and fan is spinning fast and loud and after awhile the engine heats up according to the sensor , I check the coolant level and it was low so i waited for the car to cool down and i topped it off and started driving it but the fan is still running fast and the engine heated up again.  
I waited a couple of hours and tried driving it and the car drives fine with no issues.  
Do you think there is a problem with the sensor or WTH is going on ?  
Thanks

Have you checked to see if the coolant is still full?

Keep adding coolant until it stops needing it. You left air in the cooling system and it is taking a while to burp out.

IF you don’t have to stop adding coolant… you may have a bad head gasket and the coolant is going out the tailpipe
