Phantom 820 + Swiftech H320 Fan Help

[yash6153]

Hey,

I'm currently using a Phantom 820 by NZXT and for liquid cooling a Swiftech H320. My problem here arises with fans. 

For those of you who don't know the fan layout for this case. I'm using a 360mm radiator on top for my processor and it's in a pull configuration (Pulls air). At the side panel I'm using one of there's 200mm fan for cooling my 780Ti and at the front I have another 200mm fan provided by NZXT to cool down my set of WD Blacks. Other than that I still have a 140mm fan behind which I don't know to put it into a intake or exhaust fan. 

The problem is here, this is my first build and well I don't know much about airflow and stuff. I was thinking that since all fans couldn't be intake I have to put a exhaust fan there somewhere. My question was would a back 140mm fan be enough for this humongous case or should I even use them bottom slots for it? And forgive me but science isn't my strong suit but isn't the thing that hot air is light and therefore flows up?

Thank You

Do the fans on the H320 pull air through the radiator from outside the case or inside? I didn't quite get that part.

all fans can be air intake as long as they are filtered. the case is large enough

to support all intake. rear i/o exhaust rest filtered intake.

 

remember, filtered intakes usually knock half the rated spec of that fan. it almost

takes a 4:1 ratio (if same rated fans) to make a balanced "pressured" scenario.

 

convection principle is correct, but with as much turbulence inside the case, the flow

pattern is directed with fan flow, not convection. if no flow, then yes, convection

could occur.

from outside the case so fresh air comes in
