Overheating in silence


Many computers and electronic devices have a cooling fan. Most of these fans can run at different speeds, depending on the ambient temperature and how hard the innards of the device are working at any given time. But these same devices are really bad at warning you when they run into trouble, e.g. the room is too hot or something is making the processor stay at full load. When problems strike, they keep running the fan at full speed, or just shut down abruptly.

Obviously, the technology for monitoring and regulating the temperature is already there. Why not take this one step further, and actually let the user know when thermal problems are about to strike? That’s a lot better than the silent, almost pathetic way that most devices overheat and shut down today.
