Still amazed that people worry about temps. Why does it matter? If the notebook gets too hot then it will shut itself down as a safety mechanism to prevent any damage. There is really no need for a user to monitor it.
Maybe people are worried that the computer will shut itself down as a safety mechanism at an inopportune time. Or maybe they're worried that a CPU running at a within-spec 80C all day will shorten its life, and will die just as AppleCare coverage ends. There's no reason to not want a computer that runs nice and cool.
CPU's are designed to run to a certain level all day, every day. They can run hot without any issue, it's in their design to do so.
Some people need to focus on their work instead of wasting time monitoring things that don't need to be monitored.
