i have a modified aopen hx-08 with various intakes and a blowhole on top, now i noticed that the pass-through section that divides the top half from the bottom half is rather small, and i plan on breaking out the dremel to increase size thus increasing airflow, but my question i am asking is that if i place a spare 92mm sunon fan over that pass-through hole, will that provide good suction, taking the heat out of the bottom of the case passing it up to the top blowhole and out of the case? or is it just overkill?.....i guess it is sort of like ducting the air inot the top
