I changed the pin both in the code and the arduino, and the fan did not move with modulation. I used pin 3

You may need the filtering circuit support Bill linked to a few post back so you get closer to true DC.

i dont have in hand a 0.1mF, the closest ones I have are 6800 uF and 1uf, which do you think will work best?

I'd give them both a try and see which one works better.
