automatically controls fan speed depending on the current CPU temperature and to 
keep  it  with  a  specific  operating  speed.  When  the  current  CPU  temperature  is  over/ 
under the setting temperature, the CPU/ system fan will run at the corresponding speed. 
In  this  field,  you  can  set  the  CPU/  system  fan  speed  and  the  target  temperatures  by 
moving the square.
 Important
The changed settings will become effective after you save the changes and reboot the  system.
