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.
We provide the following User-Friendly protection features:
1.Fan-Off Control: The motherboard detects the status of the CPU fan and protects the CPU by
automatically disconnecting the power supply. The default value of this function is Enable. After
booting up, the user may disable it.
2.CPU Socket Sticker: Users will find a sticker on the CPU socket, which reminds them of the
correct usage of the K7 CPU.
3. Heat Dissipation Paste: Heat Dissipation Paste is included for all Socket-A motherboards, to
enhance the heat dissipation capability.
Furthermore, we strongly recommend our users to enable the function of H/W monitoring in the BIOS. This
function, together with the FOC, provide the total protection to the CPU and allow it to maximize its
performance.
