well i have a top mounted PSU which sucks air in from below and flushes it throught the back.

im currently using a stock cpu but going to upgrade it to evo 212.

and i have a rear fan just next to the cpu.

my gpu is 7870 with fans facing down. it is idling at 36-38C. (problem?)

how is the airflow pattern here? good? bad?
i do not have any front intake fans as my case does not support it.
do i need an intake fan?

i do have an extra fan which i can install on the side panel of the case (the side which is take off in the pic)
should i put that extra fan on the botton of the side panel or in the middle. And should i make it intake or exhaust?

the pic is here : =138500195&filters[recent]=1&sort=1&o=1]http://

If all your temps are fine , you should be ok.

No on the bottom.

Side intake won't hurt but not needed if your temps are good.

typically, intake fans are positioned at the front, side and/or bottom. Exhaust is usually at the rear and/or top. Since you have no front intake available, I would add the fan to the side panel and have it as an intake (blowing outside air into the case). As far as location (bottom/middle) it may depend on if either location would cause interference with existing or future components.

it is slightly on the higher side
like my gpu idles at 36-38C

should i give an intake to my gpu like i showed in the drawing? the downmost arrow.

and i was mostly worried about perpendicular kind of airflow with the psu cooler

here is a demonstration : =138500195&filters[recent]=1&sort=1&o=0]http://

If your hardware temps are good you should be ok.

Extra fans don't always mean better temps.

so that perpendicular airflow is fine? just worried about that.

The ideal airflow situation is the one I posted above , but you don't have all those options.
