I didn't mean to pour cold water on your idea, but all the power supply fans I've seen have been small and quiet things. The fan I put in was BIG and bloody noisy and blew a huge amount of air when I tested it before fitting it. (It also draws a lot of juice and flattened my battery pretty quick while I was trying it out) But once its in the bus and trying to push the air through all that convoluted ducting, there's not a whole lot of power left by the time it gets to the windshield. This is just my experience FWIW. The results were disappointing, although still a big improvement, so I'm going to try a different approach with two fans. Andy E. A.C.Erskine@lut.ac.uk
