I was wondering this, as each day perhaps once or twice my SP3 will heat up significantly, nearly to the point where I can not rest my hand on it's rear (lol) for any length of time. Does anyone know if this does any long-term type damage? Or has this been figured into the design of the thing? Should we be concerned when it heats up, or is this a normal sort of day-to-day operational normalcy for it? One would think if anything got that hot, it couldn't be good for it, (on some level). Thanks!
