So I have a Phanteks P400 case, obviously.

I have 4 fans, with two more coming in that I will probably not use. The front of the case can fit two 120mm, the top can fit two 120, and there is one rear 120. I'm saying only 120mm, cause those are the 4 fans that I have.

Right now I have it with two intake on the front, one on the top-front, and one exhaust in the rear.

Would it be more efficient to run two intake on the front, one rear exhaust, and one top-rear exhaust?

Technically the front can fit 3 intake fans, BUT, you have to remove the case divider and that requires re-doing the LED strip and I don't feel like doing that. I will eventually, sooner rather than later, be swapping out the 120s for 140s all the way around, but both case fans died and I needed something in there and a pack of 4 120s was cheap, lol.

You have it set up just fine. You do want most of the air going from front to back. Feeding your CPU and GPU heatsinks is most important. Having the top front set to low is good because it'll help kick out any residual hot air that rises. Personally I would have the back top occupied instead because it's over your CPU cooler.

How's your CPU cooling?
 


Well, right now the computer is down for a couple days so I have time to get it set up how I wanted, within financial respect, at least.
I decided to not be a lazy bitch and I took off the plate to let me put in three fans on the front, so now it is set up for 3 intake, one exhaust on the rear. I may order another 140 and put it top-rear for a secondary exhaust fan.

I'm just rocking a FX6300 that I doubt I'm doing to OC cause I have a crappy mobo that can't really handle it, and I always have my AC on when I game so ambient is fairly low.

I don't want to add on the fans I have coming tomorrow because they have LEDs in them, so I'll be pretty much stuck leaving my case LEDs on white or purple (fans LEDs are purple). But I will see, I might end up throwing the rear-top exhaust fan on just because air flow is good.

Then again I may just wait till the thing is up and running and the GPU is OC'd, then stress test it and see how temps are.

Ugh I dunno I'm so indecisive. lolol But thank you for your help!!

Edit: I think that'll be the plan. Leave it how it is now, stress test it, if it gets too hot I'll order up a 140mm and add a rear-top exhaust fan.
 


Sounds good:) I think we all like our PC's just a little better so we never really ever finish a build so the indecisiveness is to be expected but your plan is solid.
