How would i wire two (2) 120 mm Y.S. Tech fans to rheostat(s)?
Would i use 2 rheostats, or just one?
I have the 4 pin connector for my PSU instead of my motherboard. Can anyone help me out with what wires to use and all that?

If you have a rheostat that can cope with the power of both the fans then paralell link them and connect to the rheo.
Otherwise Stereo Hi/Fi amps use two layer rheos for volume and balance control. basically two rheos with one knob.

check radio shack or other favourite electronnic supply store place =) and see if they have one of those, that can cope with a certain number of watts.

You have to see what your fans are marked at. if they are marked with an ampere (A) reading, just multiply that with the voltage they run on (I assume 12v) and you get the watt they draw. get a rheo that can cope with some more than that to be on the safe side.
