I started reexamining my case airflow setup after my motherboard died a week ago prematurely (replacement on the way). PSU metered fine w/ normal acceptable fluctuation. There was neglected case cleaning that led to built up dust on certain fan blades, cpu & gpu sinks, along with some webs in corners inside the case. Cables were routed properly.

I read other Coolermaster HAF airflow setups on Tom's HW and I still have some unanswered questions...but first here are my specs and push/pull setup.


MY SETUP

Case: Coolermaster HAF 912
Mobo: Asrock's Z75 Pro3
CPU: i5 3570K
CPU Cooler: EVO 212 (in push to rear) (horizontal mounting)
GPU: XFX Double D HD Radeon 7870
PSU: OCZ Fata1ity 550W w/ 135mm fan

FANS (in push)

200mm Front: Coolermaster Megaflow (110cfm) (this is stock 200mm and im assuming its a megaflow)
140mm Bottom: Coolermaster http://www.newegg.com/Product/Product.aspx?Item=N82E16835103078 (60.9cfm)
200mm Side: Coolermaster Megaflow (110cfm)
CPU Cooler (120mm): EVO 212 w/ the stock Coolermaster fan

FANS (in pull)

200mm Top: Coolermaster Megaflow (110cfm)
120mm Rear: Coolermaster (i think its a stock case 120mm) (maybe 45-50cfm?) (the blades dont look like Sickleflow or Blademaster coolermaster fans)
Bottom Mounted PSU (135mm fan): OCZ Fatal1ty 550W (not sure cfm or rpm)


Here are some of my unanswered concerns...

Too much push?
Positive v. negative v. neutral air pressure?
Side push fan interrupting the "S" snake airflow pattern thus creating hot air pockets around the GPU area?
Both a bottom push fan and a front push fan?

Thank you very much in advance for any advice, opinions, insults, etc..
:)

Ensure the fan setup looks like the image below and you'll be fine.
