buy cheap thermal take kit, it has a coolio metal dial which is sure to not fit in on any case! it works though , im using the heatsink fan included as the 1 case fan since it blows so much air, and im using the blower to pump air out, both which i can control from an outside console.. sadly you probably wont be able to control the existing case fans but if its really a big deal, just buy a kit with coolio dials no doubt
