Get yourself the HD fan connector off a broken mobo.
Most Thinkpads all use the same connector.
Hook it up to a 5V power supply and test all you like.
Put a potentiometer in the + wire to be able to vary speed.
Looking at the plug, the red wire = +5V, black or blue (middle wire) = GND, orange (or other color) is RPM control
You only need +5 and GND for testing.
