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. S/W Simultaneous Signal Follow-ups techniques and Auto Power Off
System are included to prevent all 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:
(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 receives the information of CPU fan revolution, it continues
to function normally. If no signal is received, it will inform the system and disconnects 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. CPU fan with sensor pins 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
disable.
