oh wow I'm an idiot, didn't even see that we have the same case :P
yeah, the phantom's airflow is pretty good but not top of the line anymore, it would be safer to go with blowers (which are loud and I honestly hate them).
to be honest, how hot does your CPU get on load? you have a really good cooler and you should be able to get away with after market axial coolers if you just add a few fans to your phantom
Currently I have my i7 875K overclocked to 4.13 Ghz and the load temps while running Prime95 are 80 degrees C max. While gaming the max I see is 65 degrees. I already have all the fan slots covered. Below is my setup:
140mm Front Intake (76 CFM)
120mm Bottom Intake (69 CFM)
120mm Front 5.25" Bay Intake (44 CFM)
2 x 200mm Top Fans Exchaust (166 CFM Each)
1 120mm Rear Exhaust (69 CFM)
So my exhaust is greater than Intake at the moment. Is there something that I could change?
