If you like rrdtool graphs, you might also look into Cacti -
http://www.cacti.net/ - it's a GPL (free, as in beer) web front end to this,
and has some interesting abilities, such as the ability to install an add-on
that will monitor any of your datapoints and take threshold-based actions.
In your case, you might have your CPU temp graph, and then set a threshold
alert that emails you when the temp crosses 70F, for example.

The Cacti User community is pretty decent, as well. People have contributed
(for example...) add-ons that query the datafeed used by Weatherbug, which
provides pseudo-real-time weather data info from a variety of weather
stations, giving you the ability to create RRD-type graphs of temperature,
humidity, dewpoint, wind speed, wind direction, etc., etc. 

I'm a pretty big fan of Cacti.
