Computer fans are almost always brush-less, actually never seen a brushed one. Because the electrical noise is too high. She 3 pin motors are simply two power pins plus one tachometer pin, which you generally only want to determine if the fan is failing. I could be wrong about this part, but I expect that they are single voltage and reducing the voltage may or may not affect the speed much and possibly could damage the fan over long use. However, I seem to remember some schemes to make 3 wire fans speed controlled. it's worth a look online I suppose.
