Both mine are on a controller. I would forget to flick them on. They dont come on unless I spend 2+ minutes idling, they spin up for 30 seconds and cut off, and then another two minute period.

 

well ill be using 1 mark VIII fan which is supposed to be 2 speed fan and capable of a respectful 4800 cfm i was hearing. i dont want any switches but i do understan the benefits of them as just in case, i just hate trying to find a spot that looks smooth and flowing with the interior and would be looking like crazy for a switch with same look as all of the other switches that are factory. Raptor what controller r you using sounds like a good one, does it come on with a/c also?
