Thanks COcyclist, I have to admit that the fans are pretty loud at full speed
If you look at the comments on line that is one of the complaints about the Tornado fan. They come with a variable speed dial on the plug and if you only go about half speed, they are not too bad. The other thing I like about them is that they only draw 2 amps at high speed and only 1/2 amp at the lowest speed. This is important to me since I have a alternator delete in the car and need to manage my amp draw closely.
I have seen items like you describe that race car drivers use to stay cool, as I guess they also don't want any drag on the performance of their cars either.
