Concept 30 did the chicken dance!
Joe K: The fan is a standard 486 computer fan. You should be able to pick one up for free or really cheap at any computer store. If you don't have a computer store local, you can get one at Radio Shack, but they are a bit pricier.
I'd say it would work great on your 110. You would probably have to rig a small battery pack to power it. It needs 12 volts, but of course mine is running on a standard 7 cell Nicd, so you can be under that cap quite a bit. A small lithium 123 or 234 pack should work great and add very little weight.
