I installed the new driver. For around 15 minutes I had fan2 value=20 (about 1150 RPM). I did some changes in the sensors3.conf file, then sensors -s, was OK. After some try I have fan2 =3D 0 RPM. I did cold boot, reinstall driver,=20 reinstall lm-sensors, still 0 RPM. I can't find why it's not working any more. Any idea? TJunction and vocabulary: This term is for me as well the temperature of a PN/NP, etc junction in=20 a electronic component mainly used to calculate the radiator. In the CPU/motherboard environment it seems to be the temperature at the=20 junction between CPU and motherboard, at the pins. I had this info and I wrote the vocabulary list from the following link http://www.overclock.net/t/1128821/amd-temp-information-and-guide/70 in the post #73 These are mails from AMD support so I suppose the definitions are good=20 at least for AMD. However this other link is more like I use to know. http://www.alcpu.com/forums/viewtopic.php?fc&t=892 I will try to have again the fan value and let you know _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
