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.
“FOC” includes the following functions:
(1) Simultaneous Signal Follow Ups: Before the system enters the O/S,
H/W will detect the signals of the CPU fan pins, get their
revolution information and send it to the BIOS.
(2) Auto Power Off System: If the BIOS gets the information of CPU
fan revolution, it goes on working normally. If not, it will
inform the system and have the power supply disconnected
immediately. Thus, the CPU is protected from over heating.
Note: The following must be observed to secure the normal functioning of
“Fan-Off Control”:
1. CPU fan with sensor pins must be used.
2. CPU fans approved by AMD are strongly recommended.
3. The “HOT KEY” function is provided for the CPU fans without
sensor pins, to avoid the power off. Users may press the “Insert”
key to jump over the “Power Off” mode; go to the BIOS and
disable “FOC”. Now system can be booted normally.
4. The power connector of the CPU fan must be connected to the
specified “CPU Fan Connector” on the motherboard to secure the
normal functioning of the system.
