My case has 2 fans that are 4-pin and i connected them to my motherboard when i first built it. A couple days later i wanted to install another fan for some better airflow. It turns out the fan is a 3-pin connecter. My motherboard is the Asrock b450m pro4. There is one slot in my motherboard that has 4-pins on top and 3-pins on the bottom. Underneath that it says "Power LED and Speaker Header (SPK_PLED1). Can i still plug my rgb fan into it? Will it harm my motherboard in any way?
