Part 3.16: Fan

Because the FPGA chip generates a lot of heat when it works normally, we
add a heat sink and fan to the chip to prevent the chip from overheating. The
fan is controlled by the FPGA chip. The control pin is connected to the IO of the
BANK16. If the IO level output is low, the MOSFET is turned on, the fan
operates, and if the IO level output is high, the fan stops. The fan design on the
board is shown in Figure 3-16-1:
