As sorbus points out, this is CPU temp, not the overall computer. The base was at around 45, I think. I guess it was an overheating damage, but could not know.

Since then, I've avoided CPU intensive things from happening on it, and the usual CPU temp is now around 60º. Which looks pretty high, but manageable. I considered buying a lower platform with cooling (they sell it in some computer stores, plates with fans on them) but gave up.
