So I'm still pretty green to circuits and the like so when I did the calculations and came to my answer it seamed way to easy...
Ohms Law: I=V/R or in my case R=V/I
So my power supply pumps out 45v @ 3A and I want 12v so I don't fry my little heat sink fans. That being said the voltage difference is 33v
Thus, R=33/3 and R=11 Ohm
So I need 11 Ohms of resistance to get 45v@3A down to 12v@3A; right?
Mmmmm, circuits (nuts)
