Wood stove top fan in smoker?

Has anyone tried one of these wood stove top fans in their smoker?

It says that it starts at 230 but I would be curious to see if you could get any movement at say 145-165 where we usually smoke our sausage.

I am looking for an option to get a more even smoke in the smoker. Its starting to look like a convection oven fan is going to be the solution but thought this looked like a cool idea for a lot of operations. :yahoo:

Those rely on a temperature differential to work. So the base sits on a wood stove at 250 deg or whatever and the air temp is 70 and you've got 170 deg of temp difference. Unless I don't understand how you intend to use it, I'm not sure how you get that difference.

Most of them use a stirling engine. pretty cool how they work.
