Hey in the process of building my first PC. Can someone please help me out with connecting case fans to MB, i dont want to mess up.

Case: Corsair 200r ATX
MB: Asrock H97 Pro4

I got a upper back fan and a middle front one. The both have female 3 pin connectors. My MB fan options are: 3 pin PWR_FAN1, 4pin CHA_FAn1, 4 pin CHA_FAN2

Im stumped weather to connected both to the cha and forget the pwr, or should one go in the pwr? Thanks a lot guys waiting for responses

the PWR fan is to connect the fan from a PSU, so the fan can be controller from the motherboard. however. if you dont have a fan connector comming out of your PSU, you cant do that. in that case you can just use it as a CHA_fan. and controll the speed manually
