A heat sink and cooling fan must be in place whenever power is applied to the CPU. Either a
clip-on or stick-on type may be used. The fan must be a 5V type. Ball bearing models are
recommended for longevity. The fan connects to header J13 for power with the positive lead (red
wire) connected to pin 2 (the pin nearest to the CPU chip).
