Hey guys, I just got my new case haf 912 :P my question is : 

200mm megaflow fan in front Intake
120mm coolermaster that come with the case on top for exhaust
120mm coolermaster that come with the case in bakc exhaust 


thats good or I need more ? thx 

Here s my rig http://ca.pcpartpicker.com/p/AQUL 

should be quite enough if your not planning on going crazy overclock's ofcourse if you feel like you need more air you can always add 1 fan on the side and 2 on the top

 

im not overclocking at all so my setup is good ? :P

yeah
