Optimal Fan Placement in Antec SX-830?

I have 2 Sunon 80mm 45cfm and 2 Antec 80mm (27cfm?)that came with the Antec SX-830 case. I have the Sunons mounted in the front of the case with the top front Sunon blowing out and the bottom front Sunon blowing in. I have the Antecs mounted in the rear of the case with the top rear Antec blowing in at the HD Drive Cage and the bottom rear Antec blowing out. I placed them this way to get some airflow onto the 7200rpm 75GXP. My question is, does this seem optimal? Or would it be best to have two in front blowing in and two in the rear blowing out. What do you guys think?😎
 
I think you're best off putting the two front fans as intake, and the two back fans as exhaust. The way you have it, you're probably disrupting a lot of the airflow.

I have the SX830 and I put the two Antec fans that came with it in the front both as intakes and then put two Sunon high output fans in the back as exhaust fans. With this arrangment my case temp is the same as ambeint room temp. The way you have it I would think that it would disrupt air flow in the case.
 
how bout having an antec/sunon fan in front, and antec/sunon fan in back? it'd be almost even, the power supply would be exhausting a little more air 🙂
 
I'm unfamiliar with that case, but you're wasting most of the fans' effort if the fans are adjacent and blowing opposite directions. It's like having adjacent bedroom windows with one fan blowing out and another blowing in: most air-flow is between the windows, not across the room. This only "works" if what you need to cool is dead-between the fans!

Front-in/back-out is a better in general, 'though we can cook up exceptions if we want to get tedious about this.

 
What all of these guys said is true. I don't see any need in bumping this message up anymore. Take their advice. 🙂
