Hardware Monitor Setup

There is a LM78 chip on your board which can monitor on board
system voltage and fan speed. The voltage monitoring will
cover +5V,+12V,-12V,and –5V.
Note: Normal CPU Fan RPM is over than 5000 RPM. If your
CPU Fan RPM is less than that figure, something is
wrong and the CPU will be in overheat condition. Make
sure that the connection at CN12/CN13 is correct.
