Hello, I have a Antec three Hundred, and a corsair h55, I want to put 2 Antec 75003 79 CFM fans on it, and mount it on the rear of my case, also I have 2 front green LED fans that have a max CFM of 50 (but I can adjust cause they are 3-pin) I am wondering what speed I should run the front ones at in order to get good flow, also , I have an EVGA 760 with ACX ( dual fan) and I am wondeirng if I should get a side or top mounted to dispurse air from that. Thanks!
