I've noticed that my Kindle Fire (fittingly, maybe) feels very hot when I am using it sometimes. Obviously, common sense would dictate that picking the device up off of the surface it's sitting on is an effective way to have air flow over the surface of the rear of the device.
Even with this quick fix, I still worry about the device overheating. Is there an active technique for cooling the device down so that it won't sustain damage? (I had thought about a laptop sized cooling mat, but this may be overkill)
Obviously, shutting down the system and walking away will help it to cool off, but I'm looking for something that works while the reader is in operation.
