Push/Pull or Push/Push?

[dg9nym]

I've decided to buy a hyper 212 cooler. Would it be better to use a push/pull fan air flow configuration or a push/push configuration? I'm leaning to push/push because I like the idea of air flow from both sides. My case is very well ventilated and has plenty of air holes from all sides.

always push/pull, otherwise the fans are fighting each other.

Really? I was thinking push/push would be better due to the double amount of airflow from both sides.

OK, maybe I mistook your post. What is pushing and what would be pulling ? case fans ? nothing to do with the 212 ? Front and back pushing in ? and what pulls out ?
The whole story here.

I was thinking that both fans on the cpu cooler would blow on the metal parts. Air intake wont be a problem as my case has airholes all over. Im just worried about outtake

the two on the 212 should be push/pull. Any case fans should exhaust air.

push pull gives you more tubulance though the fins.
push push, gives you more static though the fins.

Turbulance > static to some degree (unless you got a very restrictive air path), because turbulance allows heat exchange by agitating the surface area more.
Static is required when you have restrictions, and you need to work out those restrictions which can cause turbulance.

In a heat sink, unless you got a dense rabbit field, of dust bunnies, the required static pressure can easily be generated by push + pull, that you would probably want the additional tubulance.
