BEST AIRFLOW PLAN FOR CM 430 ELITE BLACK

I have exactly that case, but I don't have a dedicated GPU (Running IGP) and I only have the intake 120 mm fan included with the case, and it's enough airflow to my case.

You should get a 140 mm fan in the front to intake more air, and a 120 mm in the side window to direct cooling to the 7950. That should be enough for the GPU, and leave that exhaust.
Also a good cable management improves airflow, but in that case is really difficult to do any type of cable management.

We kind of have the same case. Let me show you mine.

Photos dont do the wireing justice. The fan wire gets tucked in next to the power supply after i close it and all the wires from my power supply are really tucked behind the hardrive case. They popped out when i moved my computer out from the desk to open it up. should probably zip tie them to the cage.

Oh and some of the pictures are backwards xD

Thank you guys! I got a Seasonic X-650 and its a fully modular. Now my cable management is a bit better now. Used zips to hide the big ATX cable and 8pin cpu cable behind the hdd rack.. Much better now. I will buy two of the stock fans that came with the casing from ebay 'cause they are so silent, I have to open the case and bring my head very close to hear it. And then there is no noice to be heard..
