Hi!
I want to change the fan in my XBox (not a 360) to a more silent one.
Problem is that the current fan runs from 6v whereas the commonly available silent fans are 12v models.
The fan is controlled from the motherboard which outputs the driving 6V
but the hard discs run at 12v so I can get a 12v supply.
I'm wondering if I can run this through a transistor in some way.
Whereby the base is fed the 6v from the motherboard and the fan is in series with the collector/emitter.
I'm ok making circuits from diagrams but knowing what sort/power of transistor I would need in this scenario and whether a resistor would be needed from the 6v to base.
Could it be as simple as one small transistor and a resistor - or am I getting my hopes up (again)?
I'm assuming that if I get 3v at the base I want 6v across the fan (1v->2v, 5v->10v, 6v->12v etc)
So maybe I should be looking at some sort of voltage booster?
Cheers
