This DC fan material is high quality and special (for example, it has copper inside leaves,  so it works very stable and slience...), and it has a brain---programme chip on PCB, controls DC fan's work: the air flow will be bigger and bigger when temperature increases, 
and when it cooler, the speed will slow down --- this way to protect machine and save 

Spec information 
DC diagonal compact fan (sickled blades)
