Why don't you look at the datasheet that shows both darlington transistors?

They are both the same except the TIP120 has a very high breakdown voltage and the more expensive (costs one penny more) TIP122 has an extremely high breakdown voltage. But the voltage in this project is only 12V so either Mosfet  darlington will be fine.

 

We do not know how much current your motor uses so it might overload the darlington transistor.

Where are the Mosfets that I was thinking about?

DC FAN Motor Speed Controller Regulator Circuit Works ON Principle of Pulse Width Modulation (PWM) technique , By Using This Technique Controlling Of DC Motor

Speed is very Smoothly And Noise Free. Tested on 12v 1 A DC Motor

For Full detail with live demo click on http://www.circuitspedia.com/dc-fan-speed-regulator-circuit/

By This Method Smoothly Controlled The Speed Of DC Motor At Negligible Noise

BY using This Circuit You can control the speed of DC Fan by tunning the (Potentiometer) volume control variable resistance. These circuits are based on 555 Timer .
