FOC (Fan-Off Control)
The newly designed SOYO “FOC” is based on the concept of total protection for the CPU, which is
very different from what is 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-up techniques
and Auto Power Off System are included to prevent possible damage caused by the malfunctioning
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:
Simultaneous Signal Follow Up
:
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.
Auto Power Off System: If the BIOS receives the information of CPU fan revolution, it continues to
function normally. If no signal is received, it will inform the system and disconnect the power supply
immediately to protect the CPU from overheating.
Note
: The following must be observed to secure the normal functioning of “Fan-Off Control”:
1. FOC only works on CPUFAN 1.
2. A CPU fan with sensor pin must be used.
3. CPU fans approved by AMD are strongly recommended.
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.
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. 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, provides the total protection to the CPU and allows it to maximize
its performance.
Note: FOC will only work during BOOT-up. Once the system enters the operating system,
FOC will be disabled.
