Cooling fan installation

[Gamerguy68]

I have a Chieftec Mini Dragon case, and need some advise on case fan installation. The situation is that I am getting temps up to 57c while playing games like Raven Shield and BFV.
My current system setup is : Shuttle AN35N Ultra, XP2800+, 9700 Pro, Arctic Cooler. At the moment, I have no case fans, and at idle, system is about 42c. I have bought 4 80mm fans, and wonder if I should install them to intake through front, and exhaust through rear?

I'd go 2 intake from the front, and 2 exhaust out the back. But get more opinions - I'm an admitted noobie.

Also, someone posted this link here somewhere - I think it's appropriate to re-post it for you:

You generally want an equal amount of intake and exhaust. However, if you can't achieve that, I would go with more intake than exhaust. This will create a positive pressure inside the case, which will force air out of all the cracks and holes in your case.

Were you to do the opposite, air would be sucked in, bringing in lots of dust with it, which will in time contribute to poor cooling.

Exhaust is more important than intake (as long as you have vents to pull air from. Put 2 80s as exhaust, and 1 80mm as a spot hdd cooler.

You dont need equal intake as exhaust unless you have a duct fitted inbetween the front and back that channel the air between the fans.

Exhaust fans help reduce the temperature better than the intake fans do. The comment about the dust collection in case of negative pressure inside the case is correct. But, you can clean the case frequently (once every two months) using a dust buster.
But, you definitely need case fans. You will have high temperatues if you have non!
