4. The fans power connector should be connected to CPUFAN1. 
Note: If the fan is defective or Power connector is not connected to CPUFAN1, the 
system will enable FOC function see below for more information on FOC 
function. 
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. “FOC”, designed by SOYO, gives    emphasis 
on the concept of total protection. 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.
