So I have a case with room for 2 120mm fans in the front and top, one for the side panel and back and I also have a hyper evo 212 with a cheap nautical 20$ fan that is pretty old on the the pulling end and a cheap cooler master on the other end pushing the hot air away and so all those spots but the top have cheap coolermaster fans that came in a four pack combo and just a cooler master and nautical fan on the cpu cooler. So the question is I just got 4 of these courgar turbine 120mm fans and wanted to know what spots would be best to switch out for these fans all help is appreciated thanks
