side air hmm...that one should be use only when u have too many add in cards (pcie), otherwise if u have just gpu, u shouldnt use it, it will just mess up your airflow
as for your front intake...a single fan covered with radiator...not really much of an airflow
put it on back of your case (exhaust)
in front put some intake fans

here example of how airflow is usualy done
BUT u have aio, u will also need to change fan at top to intake (not exhaust) to cool your VRM as those gets usualy cooled by CPU fan which u technically do not have
i have myself at front big radiator, but there are 4x 14cm fans so there actually is airflow from it
