[SOLVED] Case Fan Query.

[ron2456]

I am changing all the bundled sh***y case fans to something cheap and decent to cool in the coming 42C summer.
I will install two SickleFlow X 90cfm, 2000rpm in the front as intake and two SickleFlow X 90cfm, 2000rpm on top as exhaust. And another Coolermaster MasterFan MF120L Red, 1200Rpm,32cfm on back as exhaust.
So I have heard from @darkbreeze that more exhausts and less intake creates a negative pressure that gathers more dust but cools better.
And positive is complete opposite.
So is the current setup negative, positive or neutral since the front and tops are cancelling out.

Slightly negative, but I would not worry. It's the setup I'd use too. It should be enough for the interior of the case. If using a performant CPU cooler too, then no worries.
