Cooling 4028 fan - 12 V

Connect the PWM wire to the negative pin (the one closest to the outside of the board) of the first connector on the board.

Connect the positive and negative wire to the referred slot where the 12V jumper was placed.

Check once again if the jumper is placed in the right position to supply 12V to the Fan - Step 3

On boards with fan voltage selection (such as the Octopus boards), the voltage doesn't matter. The selector only changes which source the positive pin is connected to. We don't use the positive pin, we use the negative, which is connected through a MOSFET.

Please read this carefully. You will fry your fan if you don't supply the correct voltage!

Route the cable accordingly.
