Part 3.19: ALINX Customized Fan

Because XCZU3EGB generates a lot of heat when it works normally, we
add a heat sink and fan to the chip on the board to prevent the chip from
overheating. The control of the fan is controlled by the ZYNQ chip. The control
pin is connected to the IO of the BANK43 (AA11). If the IO level output is high,
the MOSFET is turned on and the fan is working. If the IO level output is low,
the fan stops. The fan design on the board is shown in Figure 3-19-1.
The fan has been screwed to the AXU3EGB FPGA development board
before leaving the factory. The power of the fan is connected to the socket of
J24. The red is positive and the black is negative.
