circulation fan placement?

my room is 6x10ft intake bottom on 1 side, out top on the other side diagonal,
where should my oscilating fans be ?

side walls ? or by the intake ? atm there over on the extraction wall, but i think they need to be blowing the intake air round,

do i side mount them? so blows across both ?
do i put them on the intakes end ?
what can i do,

current fan position is the green

should i move this fan to the orange or purple locations, or both ?

I use a pretty standard oscillating fan, mine is above the bottom intake. I like an oscillating fan because it stirs the air more.

Fan should be blowing gently over the top of the canopy and around the bottom of the plant
