thanks that was a good read... While I was driving I kinda though it out a little bit and estimated that once I hit 50 the fans were either hurting more than helping or it was just a pointless waste of electricity because air would be pushing the fans faster...then once I got home and thought about it I realized I had nothing to base my estimate off of..lol.I just want a fan controller though...lol....but atleast the LED's in the switches are mad tyte jdm amber...lol
