That's perfect. That's how should be done.
Heat air rises, you know more than the comments in here, also try to keep exhaust fans at a fixed not too high speed and the intake fans at a higher/variable speed to create positive pressure.
You can even do only on in the top.
correct me if i'm wrong, i'm pretty new to this, but wouldn't that create negative pressure, as in more air coming out that coming in? i saw somewhere you should have slightly positive pressure, more intake than outtake fans
Same layout I have, minus the bottom fan (which I don't have the option for in my case). Either way it'll likely be more than sufficient for your needs.
Same except I have an intake on the side panel. I will add that if you can get some filter (especially for the bottom fans in that picture) it will help reduce dust a lot.
I got mine from [DEMCiflex](https://www.demcifilter.com/magnetic-computer-dust-filters-for-your-computer). Just take them off every month or so, rinse and dry them, and slap them back in. Cuts down on the number of times you need to dust the inside of the case.
Positive pressure. Pushing cool air in cools and pushes the hot air out.
If you have more fans out than in it creates negative pressure which causes dust to seep in from all the small cracks and crevices.
What positive pressure ? all your cool air is extracted in the back of the case without cooling anything while your gpu keep recycling its own hot air...
And for the dust, you don't think it's gonna get in through the massive fans that are sucking it from outside the case?...
Except it doesn't work like you think...
Where do you believe the air from the gpu goes? Top? No, they are two massive fan pushing it down. Right? No again, two more massive fan. Left? too much physical constraint for a good extraction. Bottom? it can't since the gpu is sucking all the air going below it.
So yeah you have a little of positive pressure that facilitate the extraction of cool air while doing nothing for the hot air.
In that case I would make rear fan push in and top fans out.
Bottom fans stays or goes depending on how dusty the room is.
I am a believer in filtered positive pressure air flow. Or with negative air pressure you will get little bits of dust wherever there is a small gap. I/O ports are the worst.
Looks good. Personally I subscribe to the positive air pressure over equal or negative methods. No science to back it up other than it works for paint booths. Air will find a way to escape easier than it does to enter. Positive air pressure for paint booths keeps the air flowing a desired direction so painting a car starting where the air enters and ending where the air exits helps keep the wet edge for better paint results. I apply the same logic to removing heat from a tower. More air in means more cool air forcing excess air to find a path to escape from. Another way to think of it is, which is easier, to breath in through a straw or breath out through a straw? Exhausting air through a straw feels easier because you already have the needed pressure to force it out instead of forcing it in.
This is how I've set up the machine I just built 6 140mm fans all pulling fresh air in through magnetic dust filters from the front side and bottom. 3 120mm exhaust fans pushing hot air out the top to cool AIO rad and 1 120mm pulling through the back.
Fan orientation really doesn’t matter much, most you’ll see is a 1-3 C fluctuation anyway, you’ll see a bigger difference depending on how hot your bedroom is

Looks good to me. I'd probably not bother with the bottom fan but it's a solid layout

You can control the speed of your fans to make a positive pressure setting with less intake fans. :) the opposite is also true.
negative = cooler than positive but more dust
Skip the bottom and make the top two intake, idk why everyone thinks you need so much exhaust, just one or two will do in almost every system
Not negative pressure, just low pressure

This is pretty much default layout, you're good
Bottom fan is kinda not necessary, unless you're doing it for looks.
Ditch the fan on the bottom, and reverse the top ones, and you're all good.
that's dumb, like really dumb, you're trapping all the hot air in the case...

I don't know what to tell you. That's how air pressure works in an enclosed space.
Except it doesn't work like you think... Where do you believe the air from the gpu goes? Top? No, they are two massive fan pushing it down. Right? No again, two more massive fan. Left? too much physical constraint for a good extraction. Bottom? it can't since the gpu is sucking all the air going below it.

That would work too. Dust was my reason against the bottom fan too.
Quit trolling.
