aio AIO installed on the front: How to point the fans?

[nitynote]

I am having some questions regarding my first PC I am building.
 

I have an AIO that I need to place in the front of the case and I need to place also the fans in front. My case is an NZXT H510 Flow.

 

How do I point them? I read online Intake or Exhaust but I did not quite got how should I actually point them.
 

My case has already 2 Fans pre installed, one on top and one on the back.
 

Both of them are facing the inside of the case, I think. I can see the NZXT logo. But how do I know if they are Intake or Exhaust?

I am following this video and he actually has the same setup I have:
 

Prep: https://youtu.be/Az-XrAtX5XY?t=2498

Installation: https://youtu.be/Az-XrAtX5XY?t=3062
 

The Fan positioned like that means they are Exhaust right? So I should not do it, as far I understood ...

Many many thanks for your help!

The bit with the "grille" is the exhaust part of the fan, that's where air comes out. In that video the AiO fans are set up as intakes.
