250D + H100i Fandirections

Hi,



completely new to the forum and my last built is years ago so apologies for the noob question.



I'm just waiting for my parts to arrive and I was wondering what Corsair recommends when it comes to fan direction in the 250D.



Should the 2 fans on the radiator of the H100i:

push air in / pull air in?

push air out / pull air out?



Thanks in advance,



M
