I have

an i3 2100 cpu stock cooler fan.
One rear fan
One psu fan
Two gpu fans.
Tell me which one is exhaust and which ones are intake. I m planning to place a side fan so i neef to know the current wind flow.
 
Solution
One rear fan won't get the job done. In a proper case airflow, rear is used as exhaust, and front as intake. The GPU fans don't matter much for airflow, and the PSU fan is usually exhaust, since it draws air through the PSU back out of it. So definitely get a front fan for intake, use your rear fan for exhaust, and use a side fan if you feel like you aren't having good enough airflow.
