for different models to fit various machines the current standard computer fan 60 u00d7 60 u00d7 10 mm has been used as the basis for the fan blade and motor along with the existing circuit board this design has been improved to include a xh 2a male 2 pin power connector this has 2 pins that are designed to be soldered into a circuit board the current design is one sided and has the fan motor mounted on the back and one electronic component attached to the board in a way that takes up the least amount of height keeping the overall thickness down there are also three solder points where the exiting wires are attached this design has been improved where a xh 2a or other connector if deemed better is soldered directly to the board using a dual sided board so that the xh 2a connector can be soldered on the fan motor side and the fan motor can be soldered on the connector side of the board the other electronic components can be soldered on either side of the board whichever is more efficient for production and function the existing 3 wire solder points have been replaced with the on board soldering of the power connector the pins of the power connector are to be placed on the board as.
