okay so this is the setup so far,
120mm front fan Intake ( 80m^3/h )
120mm rear fan exhaust ( 80^3/h )
140mm top fan exhaust ( 106m^3/h )
still waiting for the hyper 212 and according to my understanding it should be pushing air outside i.e. onto the rear exhaust fan.
Right , but you can mount a 2nd fan on the 212 , one pushes the 2nd pulls air through , they still move air towards the rear exhaust fan , you just get a few degrees more cooling on the 212
