Anyone have an Electric fan between rad and condensor?

[davepl]

I'd like to add an electric fan for "emergency stuck in traffic on a hot day" situations. However, the only place I have is between the radiator and the AC condensor, and that's only about 3" of space, if that.

I thought maybe someone else has already gone down that path and found something that fits, so:

Does anyone know of a fan that will fit in that space?

Thanks!
Dave
