It seems to me that the biggest issue is the case... I don't think such a small fan can make that much noise just by itself. I'm wondering if when it's opened, you get that much noise
I totally agree. I think the case is the root of all the heat problems. They keep trying to cram everything into that little case but it just doesn't work out well as it's designed. Personally I could care less about the tiny size of the case but it increases the wow factor in the marketing - as long as they don't turn it on

It's all the other features of the GP that I bought it for. The fan is only about 1mm behind the usb ports and most of it is covered by the ports so a lot of the noise may be due to very poor airflow. There's also no venting on the other end of the case so the air can't escape efficiently. The solution is obviously just a quick fix rather than fixing it properly. Too bad - nice product otherwise.
