Make your own fan controller

Fan controllers give you a great way to exercise iron-fisted control over your PC's noisy fans, but they're often bulky or just plain ugly. You can spend days smoothing the front of your case, only to have your work bungled by a shiny bit of plastic with big chrome dials and a flashy display. Cheap fan controllers are often gaudy, while good-looking ones are too expensive; such is life.

Of course, the solution for those of you who don't want to pay over the odds for a shiny fan controller is to make a simple one to your own design. In this guide, we'll show you how to make a fan controller that allows for adjustment via resistors that restrict the voltage to your fan. This fan controller is on the simple side, but it works well if you want a quiet PC during office hours, but prefer the fans on full blast while you're mid-deathmatch. This controller does just that at the flick of a switch.
