Is my water cooling system properly installed?

Hi, this is my first time "building" my own computer set and I've also never had a water cooling system for the cpu so I'm not sure if it is correctly installed (for best air flow performance).
I've got a noctis 450 case, it has 3 fans at front and one on the back. Plus the corsair h100i gtx on top of the case, I've installed it this way:

The blue arrows is the air flowing direction. Both of the radiator fans are upsided (air flowing inside-out) , and I've seen that some people puts one up and the other down, but I don't know if I need to do that. Or do I need to put the fans below the radiator.
In case you don't notice this is a side view:

The fans are of course below the upper plastic lid.
Ps: it was easier for me to draw the situation rather than taking a photo so please don't ask for one I'll have to unmount everything.

Youre drawings are sufficient lol
I recommend putting the fan on the inside of the case, attached to the bottom of the radiator, blowing air the same direction.
It is much easier on the fans to blow the air through the rad than it is for them to pull it.

That being said, I have my fans like yours. Despite (2 years ago) when I got recommendations saying it would fit internally, it didnt. So my fans are outside because thats the only place they go.

That is actually my problem, I think that it may not fit inside. But I'll try to do that if it is possible. Thanks
