I have used 120v fans. First they are quite noisy when operated without a speed control. The put out a lot of air, most of which you really don't need, and the air flow causes noise. You will need to get a 120v 'fan' control (a light dimmer won't work) with a constantly varible speed control which includes 'off'. The you get some lamp cord. Attach the fan wires to a length of lamp cord. Terminate the lamp cord at the 'speed control unit'. Run some more lamp cord out of the 'speed control and terminate it with a plug. You can do this in an elaborate manner with a box to contain the speed control unit or just wire/tape it all to gether and hide it so long as you can easily reach the fan control. (I screwed it on tho the back of a cabinet I was using).
If you aren't handy, find an electrician to help.
