Some special features---

CPU Thermal Throttling/CPU Smart Fan 

in this motherboard are designed 

for power user to use the over-clocking function in more flexible ways. But please be caution that the 
over-clocking maybe causes the fails in system reliabilities. This motherboard provides the guaranteed 
performance and meets the demands of the next generation computing. But if you insist to gain more 
system performance with variety possibilities of the components you choose, please be careful and 
make sure to read the detailed descriptions of these value added product features, please get them in 
the coming section.     

 

1-1.1   Special Features of Motherboard 

CPU Thermal Throttling Technology

--- (The CPU Overheat Protection 

Technology)  
To prevent the increasing heat from damage of CPU or accidental shutdown while at high 
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle 
mode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40

 to 90

). When the system senses the CPU operating temperature reaching the preset 

value, the CPU operating bandwidth will be decreased to the preset idle percentage to cool 
down the processor. When at throttling mode the beeper sound can be optionally selected to 
indicate it is in working.

   

 

CPU Smart Fan

---( The Noise Management System

Only support 4-pin CPU cooler

 )  

It’s never been a good idea to gain the performance of your system by sacrificing its acoustics. 
CPU Smart Fan Noise Management System is the answer to control the noise level needed for 
now-a-day’s high performance computing system. The system will automatically increase the 
fan speed when CPU operating loading is high, after the CPU is in normal operating condition, 
the system will low down the fan speed for the silent operating environment. The system can 
provide the much longer life cycle for both CPU and the system fans for game use and 
business requirements.
