Best fan configuration [PIC Included]

So, I have 5 120mm fans in my case, (Antec P180B), and my core temps hover around 45C each (this isn't good or bad, it's good considering the 600mhz overclock) for my cpu, but when i push my gpu to 700/1050, the temperature rockets to 78C, (which, once again I know this isn't that bad for a gpu, but I want it lower).
Now, with the picture provided, can someone tell me if it would be better to switch fan A (the white, 110 CFM one) with fan B, (the one in the front of the case which is only 60cfm), or if my current configuration is good?

That's a pretty good configuration. I also have it that way (just without the front fan). One thing you can do to lower the graphics card temp is to get one of those PCI card fans, the ones that blow upwards at the graphics card (not the blower ones that exhausts).

messy, messy, messy
lol

Will the 110mm fan mount in the front on that model case? A second 110 or even slightly better 120mm front intake would work better there.

lol. They're all 120mm in size. The white one is 110cfm, and the front one is 60cfm. I just wanted to know whether to put the one that pushes more air in the front of the case or on the heatsink.

EDIT: and if you writing "110mm" was simply a typo and you meant 110cfm, do you mean that I should switch fans A and B (they're the same size, so yes, I can just switch them)

The intake is the one where you want to pull the cooler air into the case. The extra fan simply adds the exhaust in the one way air flow towards the rear and top exhaust fans. But like I mentioned earlier you could also grab a replacement fan seeing the same 110cfm for the front rather then reducing the method Antec put inplace there.

Although dont get a low quality PCI fan. Those are loud and dont help much.

buying another fan wasn't an option. I simply switched A and B and after temperature tests using orthos and atitool, my cpu and gpu temps dropped 5C under load and 8C idle.

buy those airduster things and hold it upside down so the cold liquide comes out and spray it all on the video card and oc it lol

Once you shutdown and played around moving fans you restarted in a different environment where time for cooling had pasted. Taking notes over an extended period of time is the only to actually see what changes in temps can be averaged.

Antec's method there was to add a strong fan right before the rear and top exhaust fans to force heated air into their intake flow. With that model since it lacks the twin 120s seen on the 900 that works like an assist there for drawing out the heated even with the front panel closed.
