I just built a new PC for Christmas and everything works beautifully except for the front case fan. I have a MSI B450M Gaming Plus Motherboard and a Rosewill 120mm fan in the front. Everything else runs as expected in the computer including the rear fan that came installed in the case. The only issue is the front fan that runs for a few seconds on start up and then comes to a stop. I have even tested different fans plugged into the same pins on the motherboard and each does the same thing. What could be wrong here?
