Intake on front/outake on back. Or intake on back/outtake on front for my case?

So I was wondering, which fan combo is better for airflow/dust build up.

Is having a intake on the front and a outake on the back of your pc better than having a outake on the front and intake on the back?.

Edit: And I noticed that my case has a intake on the front and a outake on the back. I thought It was the otherway around at first.

Edit 2: Apologies I got them mixed up, I got a outake on the front and a intake on the back. [00_49.]

Depends entirely on the case and components and the location where computer is going to be setup. The most traditional, tried and true configuration is intake in the front and outtake in the back(most come with the fans preinstalled that way).

Dust filters are more commonly on the front.  No dust filters you’re kinda screwed either way. There are buyable magnetic dust filters that might fit better on the back though.

Not a pro, not even very good.  I’m just old and have time currently.  Assuming I know a lot about computers can be a mistake.

i have the P400S It has nothing but dust filters, except for the back where the motherboard cutout is.

 

And I noticed that my case has a intake on the front and a outake on the back. [21-12-2019_00_44.]

 

Edit: Sorry I meant the other way around. [00_49.]

So intake on the front and outake on the back is better?. Or is it better the other way around?. I been getting into PC building only since like August or September so this is confusing for me.

If you got no filter on the back it wants to be exhaust (outtake). Intake is better if there’s a filter because less dust.  You got filters so why not use em?

The standard is intake on the front and outtake in the back. The fans should come preinstalled in the correct configuration.

I have same case as you, I’ve done quite lot off testing with fans in here and best configuration which I found so far is two 140mm high pressure intake fans in front, one 120mm rear exhaust and one 120mm on top rear as exhaust as well. 
Imo if you want to swap the order (intakes at rear) you will also have to swap fans on cpu cooler (if you dont use stock cooler), it may improve temps for your cpu cos you gonna have intake right next to cpu cooler but it will significantly impact your gpu temps, cos gpu not gonna have much air coming through this intake in rear.

Hopefully all of that makes sense ?

You want to do intake through a filter if possible.  Keeps the crud off the parts.  Makes the filter dirty because it catches the stuff that would otherwise wind up stuck to your parts. Maybe reverse them to start.

Did you flip the stock fans? The come preinstalled the other way around.

In case you're mixing up the directions, the frame with the plastic supports are generally at the exhaust side of the fan and that holds true for the fan included on the P400S.
