Computer Power Supply and Switch Wiring Questions

[rawfuls]

I was looking at fan controllers, however, my current fans, Antec Tri-Cools, are controlled through a little switch which is already connected to the fan.
The only power it gets is from the molex.
Some have modded them for the RPM regulator, however it's more trouble than it's worth.
Plus, fan controllers don't have an "off" switch :p
Well, some do, but...some don't


I was also thinking about picking up some Rosewills that are RPM controlled, variable (I had a blue 120 before, and it was freaking awesome) which also come with their own PCI controller.
I was thinking of just cutting the PCI bracket up, and mounting it on a 5.25" bay drive cover... But, well, money doesn't grow on trees!

Got it, so any switch should be fine, as long as it's rated over 12V?
