ASUS Z170-A LGA 1151 Intel Z170 HDMI SATA 6Gb/s USB 3.1 USB 3.0 ATX Intel Motherboard. i am using this mother board and i have 3 case fans but there is only 2 areas on the board to plug case fans into that are labeled for case fans, is there any other spots on the case i can plug a case fan onto? thanks.
