Hi Jean-Marc, Thanks for your comments.

They can be correct, but the fact is that we can't be certain (that's more or less the definition of a heuristic.) Maybe these machines had working diodes and were in a very cool environment. Or maybe these machines had broken diodes and were in a very hot environment. > So it's important > to give the user a way to force the sensor activation or adjust the > temperatures level for the heuristic.

This was part of my original proposal :) Either that of a boolean option to simply force the driver to bind. > Also, since in all examples the average temperature is lower than 15 > degrees C (-4,75; -15,25; -6,25; 3; 5,75) I will recommand to put it > closer to 10 degrees C. You forgot the first entry in the list: k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +17 C Core0 Temp: +3 C Core1 Temp: +21 C Core1 Temp: +5 C That one has an average temperature of 11.5 degrees C, so a limit of 10 degrees C would consider it good - which it clearly isn't. That being said, there's no perfect limit, so maybe it is OK if the above is considered OK by the driver even if I'm certain it isn't. OTOH, the above is an interesting case. What strikes me here is not the temperature values themselves but the difference between them which is pretty unrealistic. So maybe this can be another check in the heuristic. -- Jean Delvare
