I would encourage you to take this up with Dell at once. Yes, I will. They have exchanged a lot of components already though (including the whole laptop) and so far, nothing has helped. > While it's certainly possible that newer FreeBSD releases are failing > to control the temperature as well as older ones due to some change, > that does not mean that this is a FreeBSD problem - these temperatures > are so far out of line that anything FreeBSD managed to do before > should be viewed as an unexpectedly successful workaround. This box has been running FreeBSD 8 since day one. It always had trouble with high temperatures. But now that summer is coming and ambient temperatures are rising, the issue keeps getting worse. > Apart from your immediate problems, in my past experience this range > of CPU temperatures is likely to lead to early failure of the CPU, very > likely within a year or less. Yes, I am afraid that may happen. Then again, Intel's data sheet clearly states that this CPU is designed to operate at up to 100°C. - Bartosz
