I am using 18V DC motor with Continuous Current(A): 0.15A free-run , see specs here of motor

regarding power supply, i may be using eliminator with standard 2-3 Ampere...
As SCR needs to be ruled out of scene i am thinking of using BJT transistor with enough rating to start working with LM35 output being fed to its base.
Will it work?
If yes, then what rating of transistor should i choose and are there any other pheriferals(resistors,capacitors etc) required
OK , directly expressing the problem scenario .
I have a temperature sensor [IC LM 35], comparator [IV 741 opamp] , a fan [18V D.C fan], thyristor [SCR TYN612M].
Now, i want to use them over to form a circuit capable of controlling my fan speed in proportional to temperature.
Is there a way out...
