2 CPU fans Push/Pull or both pull?

[Gimpymoo]

Am getting a Xigmatek Gaia and installing a second fan.

Now, do I set them as a push/pull config, or can I have them both as pull?

If using a Push/Pull, which one is at the top of the case, which one is the bottom?

My head tells me pull from the bottom?

Thanks.

You'd want it pulling air through the bottom and pushing it out the top

Depending on the direction, You'd want it pulling cold air from the front/bottom (depending on direction) of the case and pushing hot air out the back/top.
