Note: If the fan is defective or Power connector is not connected to
CPUFAN1, the system will enable FOC function see below for more

FOC ( Fan-Off Control )
The newly designed SOYO "FOC" is based on the concept of total
protection for CPU, which is very different from currently seen on the
market. The H/W control function is used to see a passive security system of
monitoring and warning. S/W Simultaneous Signal Follow-ups techniques
and Auto Power Off System are included to prevent all possible damage
caused by the MAL-functioning of the CPU fan. With the help of "O/S On
Time Monitoring And Warning" function, provided by the H/W monitoring
system, the double-protection purpose is achieved.
