@ShahadatHossain 

 

Each fan has a sensor which controls its speed and depending on the heat of THAT area the sensor will "tell" the fan to run slower or faster.

 

I worked on hardware from different platform over 30 years and I believe our designers on notebooks do the same. For notebooks, we don't want to spin the fan where do not need to, specially when running on battery.

 

Hope this makes sense.

 

Regards.
