My Posts This: Topic Forum | Here is a trick. Stick both magnets together. Take a sharpie and mark the top magnet face. Now mark the bottom magnet "back side" still stuck together with a shapie. If you do it right you now have ID'd both polls of the magnets. Rough up the unmarked side of the magnets and rough up the two nice fan mounting holes a bit. Mix up some JB weld and apply the goo to the fan magnet mounting holes. Place the magents into the holes Sharpie side facing you, roughed side to the goo. I use a par of chopsticks to place the magnets into place. What you have done is install the magnets so you have both polls are presented to the sensor and your also balanced. The sensor will only see one magnet. When you mounting the sensor make sure you "strain relief" the wires.
 my two cents.
