Hi dudes, man do i love asking question 
anyway, I'm thinking of getting the Enermax CS-527 Case Black because i think it looks mint, and also because its nice and cheap, anyway.
My question is how do people ventilate their cases so well, as i know there is space for 3 fans in this case (correct me if im wrong), so i would buy 3 case fans. But im not the best at keeping a case ventilated as my current setup keeps dying
would you just simply have one blowing air in and 2 blowing air out? if so do you then need extractor fans, or do you just turn the case fan around the other way (how dense i know)
thanks in advance
