First "Micro Cooling Fan" on the wire material, a small motor (on the car demolished), water pipes (not soft to hard point), universal table, a small fan, six foot switch, as well as soldering pen. First, measuring six foot table with a universal connector switch, switch press down resistance is 0, not by Resistance lot on the line. The pipe cut, try size. The motor and "Micro Cooling Fan" even from the solder two wires on the motor, and then welded to one end of the switch, the other end of the iron plates, drilled a hole in the pipe opposite to iron insert. Cutting a big hole in the top, squeeze the switch (you can use hot solder pen), the "Micro Cooling Fan" small motor fixed, (note the connection end toward the inside), wrapped with tape. Switch the other end of the wire, the wire connected to the iron, solder weld.
