4.8 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
Vtt, Vcore, Vio, +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 CN3/CN4 is correct. Anyway, the above RPM
figure is for reference only. Different brand may give different
figure.
