Help for a new build

[Sarr_]

I'm planning to update my pc with an i7 9700k and an NZXT H500i, but i don't know what aio to choose.

What would be better:

An Nzxt Rl-Krx52 on the front that blow air inside,

or an NZXT RL-krx42 on the top that blow air directly outside?

Thanks for the help!

P.s. Any suggestion for another aio is accepted!

I think front > inside option is better. It will work with gpu fans blowing through back fins.

I'm not sure if it will work with aio tho, it just seems to give more natural flow

 

edit: also as i've seen in linus vids aio with under 2 blowies is basically useless
