I do have a nice AC fan I could use. I was going to use it in another
project but it vibrated too much in the tower case I was using. It was
very noisey, mainly because of fan speed I think..... It's a very fast
many bladed fan.

If I could slow it down a bit, it may be just the thing to use, However.
  Can you tell me exactly what to look for in a capacitor? My
experience is much when it comes to this type of thing.

I'm not to worried about using a temperature controlled setup.
