I have an iBook fan I salvaged from my Radeongated iBook. It is a laptop fan and it sucks in air from the top and blows it out the side. The air doesn't come straight out the side, it comes at an angle. It runs nicely at 3v, but at 5v (full speed) it is loud and whiney. You all know that regular desktop fans are quite useful. You can use them as a desk fan, laptop fooler, pc fan, etc. But I can't think of anything this small fan is good for. Any ideas?
