I need something to adjust the voltage for a 12v 172mm nidec fan for the side of my computer. It uses about 2A at full load. It also dosen't change RPM from 10.5 to 18V, but runs down to 7V.
So my question is, do I have to get a rheostat rated at 12v, or does the voltage not matter? Same with wattage, should I get one as close to 24w as possible, or does that not matter? And finally, what should I get Ohm wise?
