The fan works well, not much flow considering it draws power from the USB port along with 3 ports. But in my experience, even a powerful fan doesn't do much for a closed gaming laptop under full load. I bought this docking station primarily to use as a USB hub, so I don't have much to complain about. (The hub works fine even without a power supply, better than 3 other hubs I've had). But I'm hoping they can include a power supply so I don't have to search and risk burning circuit boards.
