It's been awhile since I have been here. I took a long hiatus to work my business, and my real job. But now I have time for my hobby, so I have a question…
I have a few PIC microcontrollers that are USB capable, and I want to use one of them to control the fan speed (individually) of the numerous fans in my PC, using software I create. Some fans will have speed reporting, some will not.
I was hoping that someone here has done this, and can help me pick the right semiconductor device to control the fans, the right mosfet, or whatever, and the way the speed is controlled. Either by voltage level, or something pulse-width modulated.
I just received my 5lb Mouser catalog and that pushed me to get back into developing with the PIC. I want to do something that I can send a command to my device and increase/decrease the speed of an addressed fan.
All I want is references to schematics, device reference numbers, et cetera, so I can make this happen.
Thanks!

EDIT: For sake of clarification, the fans are 12vdc, don't know the amperage, but I'm sure it can't be that high. They are either similar, or exactly like Panaflo fans. 80mm.
