I am going to use the speed controller (in attached image) for my 8-9 A 12V radiator motor. Is it better choice, if not, then which one would be better? Will it also cause to take less Amp from battery?
The 7555 has very low output current. The 2.2k output resistor can drive an N-channel Mosfet that can apply PWM speed control to the high current motor. PWM is an efficient way (very little current is wasted) to control the speed of a DC motor.
