the PS im using has Gray (turn on) , black (common ground), yellow 12V, red 5v, orange (power good), blue (-12V), white (-5v)ill ground the gray wire, run the blacks to a Ground terminal, yellow to a 12v, red to 5v, and orange to a +5v
This is where im reffering to the 5v line.
If the fan is not running consistently turn the power off and temporarily connect "Power Good" to a +5 volt line. This should cause the fan to run consistently when the PS is turned on. If the fan is still not running you should look for the "PS-on" line and connect it to a "Common" line. The PS-on line is in fact a switch to turn on (or off) the PS. Use your VOM and identify the correct color pair of wires for +12 volts. This is fairly easy. Pick a set of wires that ends in a plug with only 4 wires. This probably went to a disk drive (either hard disk or floppy). There will be 2 center wires the same color (probably black) and the outside wires will be different colors (perhaps yellow and red). Use the VOM with one probe in a center wire and one probe in an outside wire. What you will find is that the center wires equate to a negative post on a battery and the outside wires are the positive posts. With enough trial and error you can identify most of the colors. There will be a lot of +12 volt wires, a lot of +5 volt wires, an awful lot of "Common" wires and only one or two -12 volt or -5 volt wires. Normally there is only one "Power Good" and one PS-on wire.
Make the connection from "Power Good" to +5 volts a permanent connection (solder it with a bit of heat shrink).
