Hey guys! I just built a rig with the Cooler Master HAF 912. It came with two stock fans so what I need is one frontal 120mm, one 120mm on the side, and two 120mms on top OR a 200mm. Now by no means am I an expert as this is my first build, but I heard that getting good fans is very important, due to their life span, effectiveness, and bang for buck. I probably won't be overclocking like a mad man so there isn't a need to replace the stock fans, although I might if it ends up looking ugly :P So I just want to know what suggestions you guys have for what are good fans, and if I should go for two 120s up top or one 200 or what? Thanks!
