I've been googling up some info on these types of fans. Apparantly the regular fans that we all use draw more air from the center of the fan, and these blower fans supposedly pull air from the entire 80X80mm surface, not just a small 20X20mm patch in the middle (like the ones we use now apparantly). I'm not sure how much truth is in this, because the info I got is probably produced by a company who makes such fans. Either way I think that if one of these blowers could have larger fins, and run at a higher rpm they might be worth trying. As is I'm curious to test one out. Maybe when I get some mulah I'll get one.
