I can't fit 3 120mm lian LI fans up top on this case, a Fractal Design Meshify 3, even though I thought PCpartpicker said it could. On top of that, the SL and CL series fans dont share the same touch points for transmitting power. So the one on the back would have no power to exhaust, and my reverse flow up at the front spot on the roof can't share with what would have been the other two fans. Clear oversights, oops. So now I have what is effectively two fans up top, and two fans I can't even use.

Well, not too sure how to fix this. Anyone have ideas on how I might salvage this or get the original idea to work? I uhh... I am not sure where to go from here. Not exactly urgent, one of the parts isn't here yet and I'm still waiting on things.

Also to clarify: I can't find the article or document anymore, but I was trying to emulate a fan setup that was supposedly ideal for hot components and environments (Florida.) Standard 7 fan config, but the front most top fan is intake not exhaust, supposedly it has a great effect on cooling as it wasn't just removing the fresh air from the highest front case fan.

Well, not too sure how to fix this.

Just have two fans on top...

It'll be fine with the gap, if you're super serious about airflow (you don't need to be, but this is a hobby) then you'd want to "blank out" that gap with something. Maybe 3d print a cover if you want it to look nice. That way it's airtight.

The exhaust fan in the back is the most important tho. If you got intake in front, you'd be much better off having an exhaust in back and nothing on top. But it sounds like you're saying there isn't enough fan plugins on the motherboard? Most fans have daisy chain adapters built in, if not by a super cheap fan cable that can plug multiple fans into one motherboard slot.

But again, airflow doesn't need to be absolutely perfect. Unless you're doing crazy over clocks and living in a place that's always hot ambient temp, you'll essentially never know the difference.

It's just an easy part of the process for hobbyists to geek out over. Like trying to squeeze an extra 0.5 HP out of a drag racing car, the only reason to mess with it, is because you enjoy messing with it. The results will never be "worth" your time from a performance aspect.
