Hi. I bought Gigabyte 970A-DS3P motherboard and connected everything properly but cpu fan just wont start. Any fan i tried just wont start. Other fan controlers on motherboard are working exept cpu fan ( sys fan1, sys fan2...). I tried changing settings in bios by swithcing fan control from auto to pwn or voltage but nothing helped. Does anyone know what can be issue since i tried everything. Maybe the motherboard is faulty?
