Need advice on cooling configuration

[Dawelio]

Heya guys,

I have a question for you guys, even though I'm aware that the SFF (Small Form Factor) segment isn't that large on this forum... However, I'd still like to ask for your guys opinions on this.

How much, if any, difference would you guys say it would be between these push/pull configurations on these images?
As I'm having a bit of a hard time deciding wether to go for the thicker fan, since it has as quite significantly higher cfm rating than the slimmer fan.

But I also know that a lot of times people, such as myself, get caught on things like this. When in reality and in the real world, they won't actually have that big of an impact on performance or the cooling, such as in this case (no pun intended).

Hence many people who own the Dan Case A4 SFX case and this small AIO, only can use this AIO with the slimmer fan. So not sure if "bigger is better" actually applies in this case/scenario. Obviously saying anything with guarantees is impossible, as there's simply too many factors that plays in, such as components, ambient temps etc.

But just wondering in general here, what would you guys opt for?...

Thanks everyone,
Dawelio

TBH I think you might benefit more from a higher CFM fan that you can turn down a bit when you want silence yet if you need to crank it up a bit you can, I found that with push pull the difference is minimal but the noise from the chop is much more noticeable
