glad i found this thread....im currently trying to learn about airflow in PC cases, and at the same time, lowering the temp in my rig...i used a CM Elite 360 casing which has 2x120mm fan slot (top and on CPU), and 3x80mm fan slot (2 exhaust at the back and one bottom)...there is also a free hole on top of the GC port...in my case, the only cooler that fit my case is CM GeminiiS, which im currently using, but this particular CPU cooler makes the air blow into the CPU and also to some mobo components, making heats dissipate through the sides...so currently my configuration is 2 intake fans for the CPU port and the bottom, while for the back exhaust and top are all exhaust fans...so now if anyone can advice me on this configuration or change it for better, it would be much appreciated...and also, suggestions for exccellent 80mm and 120mm fans...
