Query: Overheats

I am on my second one of these and both had problems with overheating and all devices would then stop working. I have tried to create extra air space to keep it cool, but every couple of weeks it gets extremely hot to the touch and all my USB devices stop communicating. I would recommend looking for another USB hub. Running on an iMac with Snow Leopard.
