Ok, if you want me to call it a "speed controller" rather than a rheostat then to make you happy I'll call it a "speed controller" :-)
Personally, I'd prefer potentiometer. I had to go lookup what a "rheostat" is :-)
Either is a physical device, that changes resistance. I doubt either would be used in a computer for controlling fan speed. Incidentally, a rheostat is a variable resistance, connected in series with a load to control current. A potentiometer is a variable tap on a resistor, usually used for adjusting a voltage level.
