These poor CPU companies are busy packing more power into their chips ignoring the heat that comes along. If you are on a Gentoo machine, I bet you know that your CPU has to take compiling stuff for granted. But what about overheating ? It had almost become a kind of common routine on my laptop. While compiling something or maybe just that many applications are running, the system would simply shutdown!
Reason: Critical temperature reached on one of the cores.
