How to change the case fans on my PowerSpec G715?

I have recently bought new Noctua 120mm x 25 case fans to replace the default Lian Li case fans to see if it is more quiet ( looking to see which one it is more quiet).

I have never changed a case fan and looking into the motherboard manual I am a bit confused . The only thing I have changed /upgraded in the past is the RAM, which I have also bought two additional sticks of 8gb.

I am a bit concerned about BIOS as I have never installed anything more than RAM. If I am that worried , should i just let the technicians at my local MicroCenter do it? I would be spending money but i really dont want to mess it up. I bought MicroCenter extended warranty but obviously dont want to use it unless it is absolutely necessary. Thank you so much.

    Should be pretty straight forward. You're going to have two cables coming off of each fan. One for the fan power and control and one for RGB. The latter will be daisy chained together. Installing the new fan should be simpler. Single fan cable only. Just connect that to one of the the available chassis fan header. The board has three total. The top mounted radiator fans use the CPU_FAN header. The pump goes to CHA_FAN3, we have this set to full speed. Connect your fans to CHA_FAN1 and 2. Should be all set. They're right next to each other on the bottom, middle part of the board.
