What is the best airflow with this setup

[nivra552]

Hi guys currently I have a Phanteks evolv ATX.. I was wondering what is the best airflow for it...I have 5 140mm fans in the case..2 in the front as intake, 1 at the back as exhaust and 2 in the top (radiator fans) as exhaust also do think this is optimal?I was thinking of changing the front with 3 120mm fans what do you suggest/recommend? Thanks for the time God bless!

Linus' video explains it pretty well

That sounds like negative air pressure which you don't want. Funnily enough Jay posted a good video on the topic today.

Thanks for linking me to the video...but what do you guys suggest me doing?

put your rad in the front as intake, with dual 140's and 1 exhaust 

[PolosElite23]

Personally, I would go with two 140s in the front. Larger fans spinning with bigger scoops. Extra points for ones that are pressure optimized, since they will force more air through. You also use less fan headers and such.

 

As for optimization, Linus' video basically states that the best config based on his findings were fans in the front and back. Front intake and rear exsaust. Adding fans to the top did not really affect temps as dramatically.

 

I'd go with an exhaust at the back. 140mm. You want to get more air in than out to prevent dust and such (positive air pressure is good). Radiator I would put in the front personally.

I can't speak for @PolosElite23 but it seems like we both wanted to point you in the right direction, so you could choose what works for you. If you want it easy, you could flip around the back exhaust as intake and that should make possitive air pressure in the case. There is more to consider though, like case restrictions, fan speed, stuff like that.

Great as it is, use the 140mm fans on the top of the case

I would remove rear fan. Top fans are more than enough to exhaust.

Having no fan at the rear to exhaust would leave it open for dust to come in due to the area of negative pressure from the top exhausts. The OP's currently setup seems good.

That could be useful but would otherwise bring in dust without a rear dust filter.

True, but still better than negative pressure. And you can always get 140 filter.

Negative pressure doesn't really matter if all intakes are filtered. Cases aren't airtight.

But the dust seeps in through all the little crevises and meshing. My old PC was dusty in a month, the new one I build is just fine meaning waaay less dust.

There's no open unfiltered meshing or crevices aside for exhausts with the case.

Umm, I don't want to argue for the sake of arguing, but the case has meshing on the left, meshing above the fan and holes in PCIe slot covers. All of these places turns pretty much into an intake with negative case pressure.

 

 

Check it out on about 6:14.

Huh, my memory of the case was a bit off. In either case, filtering the rear in general would be needed.

Oh well, it happens. I'm not mad or anything, just standing behind my opinion. Filter on the back would be reeeeally helpful, that's true.
