On the contrary. Any loose sodder joint or connection of CPU or IC chip could be the culprit. As the machine cools down, connections can be reestablished. Perhaps the battery may have fully discharged and allowed the machine to reset. It's all speculation. -MrMasco

Messing with the fan settings could lead to a problem of overheating. Rather odd that it would run all the time, as they are only supposed to come on when needed. Unless the overheating was already going on and causing the fan to run more?
Try setting back to choose when it runs on its own and see if it improves. If so, then you know it something overheating.
