best way to keep MSI 7950 twin frozr iii crossfire cool using air

[beasty6]

hey guys,

decided i want to get two msi 7950 twin frozr cards and run them in crossfire

my case is a CM storm trooper and i have two corsair AF120 quiet edition fans at the front as intake
two CM storm 120mm fans in the roof as exhaust
two SP120 quiet editon fans in push/pull on my AIO

i have two spaces on my side panel for two 120mm fans, will i see improvement adding two AF120 fans here? if so should i have them intake or exhaust air from the GPU's
if any of you guys have this case and these cards in crossfire, please comment and let me know how it is

cheers guys

If the side fan positions are about level with, or just above the cards, then stick a couple of AF120's (or whatever) as exhausts.

..and ideally run then off the graphics card PWM signal so they are controlled automatically.
