You are still operating on negative pressure - you want positive pressure ie: more air being drawn in than being pushed out - and you're still overtaxing the aio by unnecessarily adding heat to it. Seriously, try it the way that has been suggested - flip the fans over (so u see their ugly backsides - which is why lian li make fans that look slick on both sides) and drawn air IN thru the side panel & radiator. this will cause POSITIVE pressure ie: now air WANTS to escape. So now you have 6 fans pulling room temp air in in an orderly fashion & *kind of* 5 fans (yes im *kind of* counting the gpu fans) exhausting the air that naturally WANTS to escape, & the gpu & ceiling fans are basically giant road signs to the air saying "this lane open, no speed limit, no toll" natural convection & positive pressure will do the rest. So unless there is a specific reason you can explain why you need a negative pressure case setup - pls just try flipping those aio fans over. If anyone else thinks im giving bad advice, pls feel free to chime in.
