Hey, I'm interested in making my own fan controller and was looking for a little advice. I have a 92 in the back and an 80 in the front, both of which I plan on wiring up seperate. My question to you all is what I should use to control them. I'm trying to decide between using switches to change them from 12V - 7V - 5V (high, med, low), or a simply just using a rheostat. Can anyone point out any dis/advantages with each? Any suggestions to make this go easier? Thanks in advance!
