I bought this fan, and it is very small but it does push a good amount of air for it's size. It is extremely quiet, versatile, and can be used in a variety of applications.
Coolerguys is an American based company that has been around since the 90s, and they seem to really care about providing quality cooling solutions. I would buy from Coolerguys again.
Tip for consumers:
I would highly recommend Coolerguys to any electronics hobbyist.
