Case Airflow Question?

According to the specs. you can have 6-120mm fans and 2-140mm fans (top) I'm using a Centurion 541 Micro ATX case with 2 120mm Thermaltake A2018 variable speed fans (one in front one in back) an AMD 440 Rana triple core CPU with a zalman 9500 heat sink/fan. My video card is the Sapphire 5770 1GB GDDR5. I keep the fan speed under 2000RPM for the low noise level and my card runs about 38-40C when running COD MW2 at top settings.much less when idle. The 5000 series cards don't put out the heat older cards can generate so having one GOOD fan in front and one in back should be just fine. Side fans are a help..if they don't compete with total air flow. you just have to have good air flow. that does not mean you need to create a hurricane inside your case! good wire management, keeping air flowing over you equipment, will work in any case.
