No, after some time when the speed of fan reaches to maximum it becomes constant.
The reasons behind it is given as..
Every fan has an induction motor which has a limit up to certain rpm. When it reaches maximum no further increase in rpm can be obtained.
If you want a scientific explanation then read below..
When fan starts to rotate , a frictional drag force of air acts against it. The mechanical (power) force produced by fan has a certain limit due to its motor's capacity. When drag force and force applied by the fan becomes equal fan gets it maximum speed and no more further increment in rpm or speed occurs because there is no more force to increase the speed or rpm, all is consumed to overcome drag.
