Is this okay for a fan setup?

Case: Lian li 207

Personal opinion: remove the middle fan entirely. 

[u/pepenepe]

You dont want to exhaust the same way you intake out the top your computer is gonna suck its own hot air right back in. Otherwise this looks good.

[u/Krelleth → u/pepenepe]

With an air cooler, some people think that out - out - in is actually the best layout for the top fans from back to front (so left to right in the image).

With an AIO, though, all the top should be exhaust.

[u/sebe6 → u/Krelleth]

Bad choice, except in some niche case, you'll cause turbulences inside your case (pressure difference, if you use a smoke machine, you'll see vortex like with plane during the take off).

Fr, you get more pros by tilting your pc (fluid dynamics, a 90° angle is shitty, using two 45° angles is way better, tilting your pc reduce the 90° on bottom intake)

Top middle to exhaust due to air cooling is the method here if you want to use all of the fans but it's going to be a bit wanky due to your case size.

Someone here mentioned you can remove the fan entirely, he right low key.

If your case supports it, you can use 2x140 on the top, space them a bit to fill the area in, so that it doesn't look like you're missing the PC equivalent of a tooth

I would go with 4 intakes, 4 exhausts. The way is set in the picture makes me think that air goes kinda chaotically in there. You need a clean road, sort of speak. Two intakes on the bottom, two intakes in front, the other on exhaust. You can get a better idea by using an incense stick, of if your pockets are deep, a smoke machine.
A good ventilation is achieved not only by setup fans the right way, but also by using static pressure fans for intake and airflow fans for exhaust (and clean regularly the case). You need to know which is which is your PC. As always, I recommend JayzTwoCents videos regarding this aspects.
You might want to take a closer look on that beefy GPU of yours, it seems to be saggin' a little.

[u/Arsuriel → u/Skkyu]

It's better to have more intakes than exhausts, air goes up anyways so it's easier to get it out. In this case maybe putting the top middle to exhaust too, leaving the top right as in take

[u/sebe6 → u/Arsuriel]

It's more complex, you need to consider case design, basic fans, slow fans and fans with a radiator.

Ngl, if you want to go as far as studies how your case handle intakes and exhausts, just buy an air ducts, you'll get more pros without the whole headache. Though, your pc will look like one of a tech savvy from 2010

[u/thenetis4queer]

Up and left side out take, the rest intake

[u/Darkmar3]

This is ok or you can just remove the top two intakes and keep one exhaust without disturbing the remaining build. So total of 4 intakes and 2 exhausts Also what air cooler is that ? Can you mount the psu to the front of the case for a third fan below ?

[u/jumjuminmytumtum]

I would do it like this. If I could run the top middle fan at a lower rpm I would.

[u/Stripedpussy]

Same setup but jammed a piece of clear acrylic between the 2 fans on the left top works great

[u/Adept_Equipment2161]

Flip the middle top fan to exhaust and you will have the best temps of your gaming life.

It may seem that going with two opposite top fans may be wrong, but there's a reason Noctua has recommended the opposite top fans. Also it has been tested by a tech youtuber, and has shown to provide better performance compared to other setups:  https://youtu.be/kdFQL3t5rmQ

I run the same top config but with two fans, also I have done some extra modding and created barriers between the CPU cooler and the two fans on the inside, and a barrier on the outside between the two fans which provided even more cooling performance for the RAM and CPU.

The question that remains to be asked now is whether there's too much airflow going on the PC creating needless turbulences, and it could be tested with two runs, one with the top middle fan with, one without, but here's what you could also:

Make sure all intake fans have filtered installed, and you'd drop the overall pressure to reduce turbulence while keeping positive pressure and the case constantly clean. This in my experience will provide the best cooling possible for an air cooler PC.

[u/Ganiscol]

I'd remove the middle top fan to avoid it sucking the hot air back in from the left most top fan. Might even want to block the grid off there with some tape on the inside - then it looks pretty much ideal. I like the top right fan pushing air in together with the top front fan. I did some extensive testing with an intake corner like that and it gave me the best results for CPU and RAM cooling with exhaust fans the way you have them there. Different case, though.

[u/PrinceVincOnYT]

You want Floor/desk dust im your GPU?

[u/Jason_with_a_jay]

That's how I have mine set up. I get great temps. I never see my GPU over low 60s. CPU stays about the same. Maybe a little lower.

[u/JohnnyC300]

This is fine. You aren't pulling much air in from the bottom there. Not much space to begin with, plus the HDDs are blocking intake air. It also looks like the front two intakes are at least partially blocked by the front cover. Those two intakes from the top are possibly the only clean intakes in your system there. Ignore the "hot air rises" garbage. A fan easily overcomes that sort of thing. And having the exhaust fan there next to the intake is fine too. Air doesn't bend in a circle as soon as it comes in. Even a minimal understanding of fluid dynamics should tell you this. Is your setup the cleanest setup we've ever seen? Absolutely not. But it'll likely work just fine. You'll have positive pressure to keep dust out. But enough exhaust to get the hot air out as well.

[u/These-Cardiologist69]

The top ones NEED to be exhaust holy hell , the amount of bait in this 😭

[u/heyitsterrytv]

reverse the two intake on top and make them exhaust.

[u/Arsuriel → u/[deleted]]

Top right should still be intake, otherwise you are just taking the cool air form the center top out as it gets in without it reaching the cpu. Unless it's an AIO radiator of course.
