I'm in the market for 6 case fans. I've been looking around and am thinking of going with Scythe SY1225SL12SH 120mm "Slipstream" for all 6. Is this a bit overkill? I was initially going to get just 2 for my cpu cooler but i feel like i could use more fans in my case. Should I go with a little less for the 4 that are not CPU fans? I'm also looking for a decent fan controller if I even need one. I don't know much about cooling so help would be awesome!
