Pc case/fans conflict question?

bought a new pc recently, and one of teh options was advanced cpu cooling, brill i thought..i'll have that. thing is the pc only came with one fan which is attached to this advanced cpu cooler and is installed as such that it blows air out the back of the pc case (where a grid for a 120mm fan to be installed is) which is good thinking since as the heat rises up the thermal cooler the fan then blows it out the back through a convinient hole





My question is if i install a 120mm fan at the back of the pc ensuring it's extracting air, will it conflict with the air flow the 80mm fan is creating attached to the cpu cooler?





heres a link of the case i have just incase

note, the fans would be about 20cm apart if installed, if that makes any difference





thanks in advancePc case/fans conflict question?
no that would help...also, i see fins/holes at the front of the case by the drive bay...is there a mount for an intake fan there? If so, then putting an intake by the drives will help cool them and complete the system.Pc case/fans conflict question?
no it shouldn't. I have 4 fans in my pc and it helps stay cooler. especially in none a/c environment during the summer
