What is generating those pop-ups? I have found that a lot of temperature monitoring programs are grossly inaccurate (and far too conservative) when it comes to processor temperatures. I always look at http://www.cpu-world.com for the processor in question first to see what is listed as the maximum operating temperature and, very often, double check this against the processor manufacturer's own website.
For example, the AMD-10 has a maximum operating temperature of 90° C, though you probably wouldn't want it there on a constant basis. I've seen some of the monitoring utilities go 20° below that, which is utterly ridiculous as a warning threshold. The databases used by a number of these utilities (and there are scads of them) are clearly not always kept up to date or may have had inaccurate information entered into them to begin with. You can generally tweak the values in the software to something that makes sense once you have the accurate maximum operating temperature in hand.
See this thread, entitled, Are My Temperature Settings Wrong?, in the Linux & Unix forum, because the topic and discussion is in no way Linux & Unix specific, but applies to how to find out what the temperature settings should be for processors in general.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
