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.

There is the answer, it was in the manual, what a wierd place to hide it
