So I took the advice of installing SpeedFan (also because download.com has Editor's recommendation), and see that the temperature of my notebook's CPU (Intel Core2Duo) is about 60C and jumps up to about 69 C max for a few seconds (by looking at the chart).
So is this near the high range? What if it is 75 C or 80 C, is that too high? (come to think about it, boiling water is 100C, so 70 C is not a low temperature.
How about if it is for a desktop, is that the same values for determining whether a CPU is too hot?
