Noob question :( - which way to install fans?

Hey guys this is a very noob question so please excuse me its my first time building. How do I know which way to install the fans on my case and how do I know if it will be air out or blow air in? :confused:

I have 5 fans that need installing into my case:
x2 high static pressure fans on the underside of the top of the case in which the dual rad will sit on top of the case (NZXT 410) - do these fans need to be blowing air upwards or down wards?
1 fan at the back of the case - this would be best for blowing air out right?
1 side fan which should be blowing air out?
1 front case fan I would like air to be blown in

How do i find out which way the fan will blow? Please excuse the noobness

there is normally a arrow on the side of the fan which tells you which way the air flows,if they dont then hook them up and see which side is blowing out the air.

Basically you want more fans sucking in than blowing out, therefore creating a +ve airflow. Ideally you want the fans at the bottom and front to suck in & the back and top to blow out. This is because the coolest air is underneath because hot air rises. As for the side fan, i would get that to suck in to create the +ve flow. Hope this helps.
