How to manage the airflow in this Rosewill R5

[SovietFred]

Hey everyone, quick question. This is my first build/upgrade and I'm upgrading most of the parts from my previous PC. A problem that I'm trying to figure out is how to configure my air flow. I know I should have more intake than exhaust to keep static pressue going but I'm not sure if I'll be able to accomplish that with my current fans. The case is a Rosewill R5 and it comes with 3 stock fans, 2 front, 1 exhaust and those are all 120mm. I purchased an extra 120mm and two 140mm fans to fill in the extra slots. Now I have to figure out how to manage exhaust and intake on this thing. One of the things I need help with is if I should orient the PSU fan exhaust into the case or down and out the case. The problem being if its into the case there's more heat in the case and if it's out the case, that fan slot that's right next to the PSU is going to be blowing warm air back in so that's not very efficient. The top has two slots that can fit two 140mm fans which is the diagram I have here: http://imgur.com/DMOkMu8 Sorry for the crude MS Paint drawing. Red arrows represent intake and green arrows exhaust.

Here there's an uneven intake/exhaust which may cause issues. The two 120mm fans in the front have no more clearance so I can't swap one out for a 140mm. All of the fans except the 120mm rear exhaust have removable filter panels in front of them so that will also restrict air flow. I'll go ahead an provide a clean picture here if anyone wants to draw their diagram: http://i.imgur.com/niGoieR.jpg

So yeah, I'd appreciate some help on this. If you need better pictures/information just let me know and I'll get back to you.

The panels of the case also have some air intake:

First, the PSU fan INTAKES air. The rear of the PSU is where the warm air vents out of. So have the PSU's fan face down to intake fresh air if your case sits on a flat surface, no burying it in a thick rug. The PSU is a self-contained cooling system.

I really don't put much stock in this positive case air flow theory for PC cases. Most cases are full of various size openings and holes. Just keep air moving into and out of the case. If you even have a vented opening in the top of a case, most of the heat in the case will escape via natural thermal dynamics, anyway. (hot air rises) All the extra fans can be just more noise. But yeah, they look cool.

The rig in my sig has a front 120mm intake and a top 120mm exhaust. The H60's fan (rear) intakes fresh air to cool the radiator and the top fans helps remove the heated exhaust. That's all I have. Nice and quite. No temp issues at even the most demanding CPU/GPU usage.

Wow that was definitely dumb of me about the PSU, my bad. Yeah I guess I'll just stick the 120mm on the bottom by the PSU and have the two 140mms on the top since the case has the 3 vent slots/areas/holes on the sides it should be getting plenty of intake. I suppose I'll just need to monitor the heat of the components for a while and see if there's any issues.
