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.
