i have one cooler before.. it's a cheap and no brand cooler.
the design are nearly same. three fans located the same as yours..
but it's a plastic made.
when i do the same as you.. the air flow out front of me..
As specially, when i'm in air condition room.
one fan located left suck the hot air out, another two are actually sucking the cool air out..
so when the air flow come out to me, my hand actually freezing.. lolz..
when i off my aircon, it's end up body hot and hand cool..

this technique of turning around the cooler are very effective of cooling down the temp, but i face the problem of causing my hand/arms freezing..
i rather take out the cooler instead of using it. hehe..
