Having issues with air cooling in a CM ATCS-840 (w/ PICS)

I hate to post this twice, but it wasn't getting any views buried in the overclocking section. Mods: maybe delete the other one if it's a problem.

I’m having some issues with air cooling in my new Cooler Master ATCS-840 case and was hoping there may be some people with ideas that may help me in this forum. I wasn’t getting much help in the Steam forums where I usually post.
Sorry for the long post; I really appreciate anyone taking the time to read it and any advice that is offered.

So I replaced my Antec 900 mid tower with a beautiful black ATSC-840. Although the 900 cooled everything very well, I was sick of jamming my big hands into tiny places, plus I never really liked the appearance of the case either. Looks were somewhat important because this PC doubles as my gaming rig and a HTPC, so it is quite visible in my hyper-masculine man cave. Quite simply, the ATCS-840 looks awesome and I love it.

The problem is that just about all my temps are 5-15 deg. C higher than with the 900.

All of the goods inside the case are identical to what was in the old one:
CPU: AMD Phenom II X4 955 @ 3.8 GHz (211 x 18; 1.5v)
Mobo: Asus Crosshair III Formula – AMD 790FX / SB750
GPU: (2) Sapphire HD4870’s (1 Gb ea.) in CrossfireX
RAM: G.Skill 4x2 Gb - DDR3 1600 MHz
HDD: WD Caviar Black
PSU: Corsair HX750W
Case: Cooler Master ATCS-840
Mobo/Fan Controller: Asus OC Station
CPU Cooler: Corsair H50
RAM Cooler: G.Skill Turbulence

Here is a description of my fan setup:
INTAKE:
Front panel: 230mm CM fan @ 750 rpm
Bottom panel: 120mm Delta fan @ up to 3000 rpm (usually @2200 rpm)
Back panel: 120mm Corsair fan w/ H50 @1700 rpm + 120mm Rosewill fan @1750 rpm in a push/pull configuration

EXHAUST:
Top panel: (2) 230mm CM fans @ 750 rpm ea.
Back panel: 120mm CM fan @ 1250 rpm (GPU exhaust)

INTERIOR FANS:
(2) 120mm Scythe S-Flex fans @ up to 1900 rpm ea. (usually @ 1200 rpm) in this position
Antec Spotcool aimed across the north bridge and up a bit to try and direct the warm air from the H50 upwards and out the top
G.Skill Turbulence RAM cooler fan

Eleven fans inside this case now, not including GPU fans. (I do plan on replacing the stock GPU coolers next week with Arctic Cooling ACCELS1 Rev 2 passive coolers, so 2 less fans then.) I'm thinking I'm either still not equalizing the air pressure, or there is just a mess of air currents blowing around in there. I realize that more is often not better when it comes to number of fans, so I’m definitely open to removing some of them.

As of now, the only other thing I can think of to do is add a 250mm fan into the side panel. That's the one thing I think I'm missing from the 900 case. It was only a 120mm on the 900, but it blew right on the mobo, so I think that made a big difference.

Here's some pics of the build, although some of the fans are in different spots since I took the pics.
