Noob question :( - which way to install fans?

[lewiswongy]

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?
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

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.

Thanks buddy you are a great help!
